    ABSTRACT: In this study, Chinese upland rice cultivars including Handao297 and Handao502 were transformed with the anti-herbicide bar gene in order to achieve efficient weed control. PCR amplification, Southern blot analysis and field Basta resistance identification in early T0, T1, and late generation T6 and T11-T13 illustrated that the exogenous bar gene had been integrated into the genome of the upland rice varieties with stable expression in successive generations. Different transformants had a different gene copy numbers, which was not related to Basta resistance. Some of the transgenic lines showed gene silencing, whereas multiple copies of the bar gene were observed in other late generation transgenic lines. Basta resistance can thus be inherited stably among generations, and an optimal Basta concentration and selective pressure are suitable for resistance segregation and breeding of homozygous progenies with high resistance. After three generations of successive Basta resistance selection in 207 T0 plants, we obtained 555 T3 lines. Comprehensive identification and selection for Basta resistance, drought resistance, yield, and other agronomic traits in nine generations yielded two promising transgenic lines, HD297T-31 and HD297T-523. Although both varieties were resistant to 0.1 % Basta, HD297T-31 possessed high (100 %) resistance to Basta while HD297T-523 showed moderate (95 %) resistance. Moreover, during the reproductive stage, the stems, sheaths, leaves, and panicles of HD297T-31 were immune-highly resistant to highly-moderately resistant to 0.5 % Basta, whereas, they were highly resistant-moderately resistant to 1 % Basta. HD297T-523 was immune-highly resistant and immune-highly resistant to 0.5 and 1 % Basta respectively. The plant and stem percentage sensitive to 0.5 % Basta was lower than 1 and 3 % respectively. Since HD297T-31 showed isozygosity, it could be used as a new variety in production.

    ABSTRACT: The degree of inbreeding should ideally be determined across the entire genome, but is instead widely measured using the pedigree-based coefficients of kinship (f) for pairs of individuals and of inbreeding (F) for individuals. For fruit trees, this biases the estimates for pairs of cross-parents and crossbred accessions, because f and F do not account for any latent kinship among the parents, particularly when these are local cultivars. Local cultivars are often important genetic resources but usually have an unknown pedigree. Several estimators have been developed for estimating kinship and inbreeding from DNA marker data. Among these, we selected the kinship estimator of Wang (Genet Res 89: 135; 2007) and the inbreeding estimator of Leutenegger et al. (Am J Hum Genet 73: 516; 2003), using 207 simple sequence repeat markers in 73 Japanese pear (Pyrus pyrifolia Nakai) and 3 Chinese pear (Pyrus ussuriensis Maxim.) accessions with high potential as cross-parents in breeding of Japanese pear. Pedigree-based coefficients calculated from accessions with all known great-grandparents were used to compare the performance (measured by root mean square errors and correlations) of the estimators. Most marker kinship estimates matched the expected values for parent-offspring and full-sibling pairs, and indicated latent inbreeding, especially among accessions with f = 0, including local cultivars. Marker estimators highlighted latent inbreeding early in the breeding program. The data presented here will help breeders identify the degree of inbreeding in breeding populations and avoid inbreeding during crossbreeding of Japanese pear.

    ABSTRACT: Micronutrient malnutrition especially iron (Fe) and zinc (Zn) has disastrous consequences for the more vulnerable members of the human society, especially poor women and pre-school children in developing countries. The common bean (Phaseolus vulgaris L.), an important grain legume directly consumed by humans provides cheap and important quantities of protein and calories and is an excellent source of some minerals (Fe and Zn) and vitamins which qualify it as perfect food. Unfortunately, many of the adapted bean market class varieties are low in these nutrients. Therefore there is need for biofortification of these varieties with Fe and Zn through plant breeding and genetic engineering in order to contribute to improved health of bean consumers. The objective of this study was to determine the mode of inheritance of high Fe and Zn concentration in selected bean varieties. Six parents high and low in Fe and Zn were crossed following a full diallel crossing design. Populations were advanced from F1 to F2. F3 seed were analyzed for Fe and Zn concentration using X-ray fluorescence. The study showed that both additive and non-additive gene effects are important in determining the expression of high Zn and Fe concentration even though additive gene effects contributed more. Narrow sense heritability of Fe and Zn was high estimated at 71 % for Fe and 83 % for Zn. Significant maternal and reciprocal effects suggest also that cytoplasmic inheritance is involved in Zn and Fe concentration. Strong positive correlation between Fe and Zn concentrations (r = 0.75) was observed suggesting that these micronutrients are not independently inherited. The positive relationship between Fe and Zn plus the negative relationship observed between Zn and seed size (r = 56) suggest that Zn and Fe accumulation is controlled multigenically or oligogenically with some genes affecting the concentration of both minerals. The variability in seed mineral concentration among crosses was larger for Fe (47–77 ppm) than for Zn (28–38 ppm).

    ABSTRACT: The melon aphid Aphis gossypii Glover is one of the most serious pests in cucumber production, often causing severe damage in commercial fields. Identifying and deploying resistant germplasm and understanding the inheritance of melon aphid resistance are required for cucumber geneticists to develop an effective breeding strategy. In this study, resistance of 30 cucumber selections to melon aphid was evaluated at the seedling stage. Six generations, P1, P2, F1, BC1, BC2 and F2 derived from the cross of JY30 (susceptible) × EP6392 (resistant), were used as genetic populations to study the inheritance of melon aphid resistance in cucumber with the mixed major gene plus polygene inheritance model with the joint analysis method of multiple generations. Eight of the 30 tested selections displayed resistance to the melon aphid. The resistance of cucumber to melon aphids was controlled by one additive and dominant major gene plus additive and dominant polygenes, and was affected by environment as well. The additive effect and the dominant effect of the major gene were greater than the additive effect and the dominant effect of the polygenes. The heritabilities of the major gene in BC1, BC2 and F2 were 63.62 %, 0 % and 70.39 %, respectively. The polygenic heritabilities were 22.62 %, 37.0 % and 9.32 %, and the ratios of the environmental variance to phenotype variance were 58.54 %, 63.16 % and 30.77 %. We conclude that selections of cucumber with high resistance to melon aphid could be screened in advanced generations.

    ABSTRACT: Progeny of certain peach crosses include plants with slow ripening (SR) fruits that do not mature and remain on the tree after leaf fall. This character is determined by a single gene (Sr/sr) that segregated in the F1 population of the cross between ‘Belbinette’ and ‘Nectalady’ (Bb × Nl). Heterozygous (Srsr) in both parents, the recessive srsr homozygote resulted in SR individuals. This gene mapped to linkage group 4 in a map constructed with SSRs in BbxNl, at the same genomic region previously found to contain a gene for maturity date (MD). An allele of a SCAR marker (PSR2) developed from the candidate gene for MD (ppa008301m), and with high sequence similarity to NAC transcription factors, was diagnostic for the sr allele in the Bb × Nl progeny, a collection of 135 normally-ripening cultivars and breeding lines, and 467 offspring of different lines segregating for this character. We developed an SSR marker, CPP15636, at this location (39 kb from PSR2), which had one allele associated with the character although a few recombinant individuals were identified. Both PSR2 and CPP15636 can be used for early identification and selection of normally-ripening genotypes in breeding programs. Data of MD in the population studied indicates that sr could be an allele of the MD gene. Given that the MD locus is partly responsible for the variability of the maturity date, we suggest that the sr allele in heterozygosis could confer desirable properties of postharvest behavior or specific maturity dates and would be preferentially selected in peach breeding.

    ABSTRACT: A dissection of the genetic regulation of protein, oil and starch contents in maize (Zea mays L.) kernels will enhance high-quality breeding. The objective of the present research was to detect the quantitative trait loci (QTL) controlling protein, oil, starch and lysine contents in maize kernels and to dissect their inheritable relationships and basis. A population of 498 recombinant inbred lines derived from a biparental cross of two elite inbred lines were grown in six environments. All individuals were genotyped with 151 pairs of simple sequence repeat markers to construct a genetic linkage map. Using composite interval mapping, we detected total 25, 13, 31 and 15 QTLs for protein, oil, starch and lysine contents, respectively, in six environments. 32 QTLs at bins 2.03-2.04, 2.05-2.07, 5.05-5.07, 6.01-6.04, 8.03-8.05 and 10.03-10.05 were stably expressed across multiple environments. Co-localizations of QTLs for the four traits were found on chromosomes 1, 2, 5, 6, 8, and 10. Part of the co-localized QTLs, the direction of QTL effects coincided with the sign of their phenotypic correlations, which likely indicates the presence of pleiotropic QTL or tight linkage among them. Additionally, seven pairs of QTLs with significant additive × additive epistatic interaction effects were identified based on single-environment QTL analysis. The results obtained from the present investigation may hold great promise for further studies of improving kernel quality in maize.

    ABSTRACT: Cassava green mite (CGM) Mononychellus tanajoa (Bondar) (Acari: Tetranychidae) is a major arthropod pest causing significant loss in the yields of storage roots and planting materials of cassava in Zambia. Its control has been mainly based on the use of exotic predatory mites as biological control agents, which unfortunately, have not established well in Zambia due to the lack of suitable host genotypes and harsh weather conditions. The current study was aimed at breeding cassava for improvement of morphological traits that are associated with resistance to CGM, which can also enable cassava genotypes to provide shelter and ensure continuous survival of natural enemies of CGM, and to determine the inheritance of these traits by assessing combining ability and therefore the type of gene action involved in their expression. Using a 5 × 5 half diallel mating design, full-sib cassava genotypes were generated out of which 300 were selected and evaluated in the field. Data were collected for CGM density, CGM leaf damage and cassava mosaic disease severity, plant growth habit, leaf morphological traits, storage root yield and root dry mass. Both general and specific combining ability effects were significant (P < 0.01) for the reaction of the F1 progeny to CGM, and for the various plant morphological traits that were measured, suggesting that both additive and non-additive gene effects play a role in the expression of the traits.

    ABSTRACT: Chlorophyll a fluorescence parameters, derived from its induction, known as the OJIP rise, are often used to characterize the structure and function of photosystem II (PSII). Under field conditions, structure and function of photosystems of crops can be affected by various environmental factors. This study was conducted to identify quantitative trait loci (QTLs) associated with chlorophyll fluorescence parameters in field-grown maize. During three growing seasons, a recombinant inbred line population, consisting of 228 lines, was evaluated for five chlorophyll fluorescence parameters, which indirectly measure: absorbed photon flux per cross section of leaf (ABS/CSo), maximum trapped exciton flux per cross section of leaf (TRo/CSo), electron transport flux from QA to QB per cross section of leaf (ETo/CSo), number of active PSII reaction centers (RCs) per cross section of leaf (RC/CSo), and the performance index on a cross section of leaf (PICS). Significant correlations were frequently observed among these chlorophyll fluorescence parameters. Three major genomic regions dispersed across chromosomes 1, 5, and 9 were detected to be associated with chlorophyll fluorescence parameters. The genomic region in chromosome bins 9.06-9.07 contained QTLs that not only showed pleiotropy for multiple chlorophyll fluorescence parameters but also showed stable expression and explained a large proportion of the phenotypic variation. Additionally, a QTL for grain yield was also detected in this important genomic region. The identified QTLs for chlorophyll fluorescence parameters in the present study may help elucidate plants’ responses to environmental cues and assist in developing marker-assisted selection breeding programs in maize.

    ABSTRACT: The stalk sugar content in silage maize plays an important role in improving its forage quality and palatability. In this study, we reported a dynamic quantitative trait loci (QTL) analysis of stalk sugar content at different growth stages in maize. A recombinant inbred line (RIL) population with 202 lines derived from a cross of YXD053 × Y6-1 was used to identify the dynamic QTL for stalk sugar content (Brix) in maize. The Brix of RILs were measured at four stages in two environments. Twenty-two QTLs affecting maize stalk sugar content (Brix) were detected by unconditional mapping method. Fifteen QTLs were identified using conditional mapping approach. No QTL was detected at all sampling stages. Six QTL, qSSC-2.1, qSSC-2.2, qSSC-2.3, qSSC-5.1, qSSC-9.1 and qSSC-9.4, were detected by both unconditional and conditional mapping. One major QTL qSSC-2.1 flanked by markers bnlg1909 and umc1635 on chromosome 2 had a relatively high net effects of gene expression from anthesis stage to 20 days after anthesis. A total of six pairs of QTL with significant epistatic effects were identified at different developmental stages. No significant QTL × environment interactions were observed. Stalk sugar content is controlled by a complex genetic mechanism, and the QTL detected at different development stages might be important contributors to stalk sugar content in maize.

    ABSTRACT: Cold stress is a significant factor influencing global rice production and quality. In the present study, two strong rice cold tolerance introgression lines (ILs) (IL5335 and IL5243) derived from Oryza sativa L. mating with O. rufipogon Griff. were used to evaluate the relationship between the alteration of DNA methylation and phenotypic stability using methylation sensitive amplification polymorphism. Compared to the recurrent parent, the level of total methylation in IL5243 was slightly increased (30.94 %) and that of IL5335 was significantly decreased (24.17 %). There were 109 (10.35 %) and 56 (5.52 %) loci showed demethylation in IL5335 and IL5243, respectively. And meanwhile, there were 28 loci (2.66 %) in IL5335 and 30 (2.96 %) loci in IL5243 showed hyper-methylation. Analysis of 17 differentially methylated sequences indicated that nine sequences had high similarity to some functional genes (e.g. CHY1, MAPK et al.), and some others were similar to retrotransposon or rice genome sequence. Further analysis indicated that CHY1 and MAPK in IL5335 and IL5243 underwent demethylation process and their expression level tested by RT-qPCR was higher than that of their parents, which suggested that the alteration of methylation modification might influence some genes expression. These results provide useful information for efficiently exploiting and using interesting wild genes for rice enhancement.

    ABSTRACT: Canopy architecture improvements are a major focus in modern maize (Zea mays L.) breeding because appropriate canopy architecture could allow for the adaptation to high-density planting and high utilisation efficiency of solar energy. Therefore, understanding the genetic basis of canopy architecture-related traits is important for maize breeding. In this study, an F2:3 population derived from a cross between R08 (representing a breeding pattern of lower planting density with large ears breeding pattern) × Ye478 (representing a breeding pattern of high planting density) was evaluated for nine canopy architecture-related traits in six environments, including Nanning, Ya’an, and Jinghong, in 2012 and 2013. Mixed linear model-based composite interval mapping was used to dissect the genetic basis of canopy architecture-related traits. Sixty-five quantitative trait loci (QTL) were identified for all nine traits through a joint analysis across all environments. More than 80 % of the QTL in this study did not show significant QTL × environment interactions, but epistasis played an important role in architecture-related trait inheritance. Nine chromosome segments were identified that affected multiple canopy architecture-related traits.

    ABSTRACT: Much research has identified quantitative trait loci (QTL) for resistance to Sclerotinia sclerotiorum in Brassica. However, the real-world applicability of these QTL for gene discovery and resistance breeding has been hampered by poor inter-study integration. This is due to the use of different mapping populations, environments and diverse markers. In this study, a physical map was constructed based on the recent Brassica napus genome release and used link QTL for resistance to S. sclerotiorum. In total, 353 markers, divided into 146 and 207 on the A and C genomes respectively, were used. This enabled integration of 35 QTLs, including 8 leaf resistance (LR) and 27 stem resistance (SR) QTLs. SR QTLs that were conserved across studies were found on A9 (from 22.5 to 27.5 Mb) and on C6 (from 29.5 to 36.1 Mb). Clusters of nucleotide-binding-site, leucine-rich-repeat-containing candidate resistance genes were identified, which provide key targets for identification of genes for resistance to S. sclerotiorum in B. napus.

    ABSTRACT: Southern corn rust, a devastating fungal disease of maize, can cause significant loss of grain yield during intermittent outbreak. Growing resistant varieties is the most cost-effective way to manage southern rust in field corn. However, the prevalence of incomplete resistance owing to rapid evolution of pathogen warrants the necessities of discovering new resistant resources. To this end, the disease occurrence of 15 maize inbred lines in response to southern rust was examined in fields located in tropical, subtropical and temperate regions respectively. Overall, the character of resistance or susceptibility was rather steady among locations for most of inbred lines although infrequent variations existed. A tropical inbred line, SCML205, displayed fully resistant response in all the locations tested. By contrast, Jing24, W1636, Zheng58, W541 and G10-2426 exhibited completely susceptible response. A 3:1 segregation ratio of resistance to susceptibility was identified in the progeny of F2 population generated from the cross of SCML205 × Jing24, demonstrating SCML205 harbors a single dominant resistant gene. Allelism test was performed to confirm the resistance conferred by a novel locus, which was designated as RppS. Genetic mapping were conducted to locate RppS to the distal arm of chromosome 10S, a region close to other resistant genes known so far. Together, our survey of the resistance to southern rust in numerous inbred lines leads to the identification of a novel resistant gene, which would be tremendously valuable for plant breeding.
