    ABSTRACT: The main objective of this study was to dissect the genetic basis of rice flowering regulated by temperature. We used two indica varieties Zhenshan 97 and Zhongzao 18, and 168 recombinant inbred lines (RILs) derived from them to estimate temperature effects on heading date (HD). Tests under four different photoperiod and temperature conditions in growth chambers showed that HD of both parents was accelerated at high temperatures, indicating that both parents were strongly thermo-sensitive. The averaged effective cumulative temperatures (ECTs), 1,120 and 1,263 °C necessary for Zhenshan 97 and Zhongzao 18 respectively, could be the prerequisite in a given condition before heading. QTL analysis was conducted with the RILs grown in both long day and short day conditions in 2 years. A total of 4 ECT QTLs corresponding to 4 HD QTLs were mapped. The major ECT QTL, qEHD10, was repeatedly identified on chromosome 10, which could explain 42.2–57.0 % of ECT variation and 39.8–59.4 % of HD variation in four environments. Overall these novel findings would improve the knowledge of temperature on rice flowering.

    ABSTRACT: The objective of this study was to propose a methodology using a factor analysis associated with genotypic and genotype × environment interaction effects (FGGE) and to accomplish, simultaneously, analyses of environmental stratification and the adaptability of maize cultivars indicated for planting in Paraná State. The analysis of adaptability based on the factor analysis was accomplished graphically by scoring in relation to the factors with separation in the adaptability quadrants. The analysis of environmental stratification were accomplished beginning with the magnitude of the final factor loadings obtained after rotations through the varimax method. The FGGE method is efficient for processing the environmental stratification and adaptability analysis. More than 70 % of the retained variation in the first eigenvalues represents the expressive part of the sum of the genotypic and genotype × environment interaction (G × E) interaction effects for this data set. The cultivars with wide adaptation and high yield in the group of the tested environments were P30F35, P30F53, P30K64, P30R50 and AS 1570.

    ABSTRACT: Drought is among sweetpotato production constraints in sub-Saharan Africa. Two studies were conducted on 15 F1 sweetpotato families (G1-G15) generated using a half-diallel mating scheme of six parents. The first experiment was conducted at Kenya Agricultural Research Institute (KARI), Kiboko, using split plot design under drought stress and no drought stress replicated twice and repeated thrice between January 2012 and June 2013. The second study was conducted in the screen house at KARI, Muguga using randomized complete block design. General combining ability (GCA) and specific combining ability (SCA) effects for storage root yield (FSR), total biomass (BIO), harvest index (HI), marketable number of storage roots (MNR) and root dry matter (%RDM) were significant (P ≤ 0.05) under both conditions. GCA/SCA ratio for FSR, HI, and %RDM under both conditions, ranged 0.51–0.76, thus, additive gene effects were more important than non-additive genes effects. G15, G5 and G7 had the highest significant (P ≤ 0.05) FSR SCA effects under drought stress while G15, G7, and G12 had the highest under no drought stress. Progenies G8-8, G15-5 and G15-8, had the highest FSR mid and best parent heterosis ranging 117.8–269.6 % under drought. Drought susceptible parents P3, P4 and P5 had the highest yielding crosses under drought,which were also high yielding under no drought [G15 (P3 × P5) and G5 (P4 × P5)]. Thus, these parents probably were carriers of the drought tolerant genes (heterozygous recessive). This suggests that the drought tolerance alleles could be homozygous recessive, which may be confirmed in further studies.

    ABSTRACT: BS20-T is a thermo-sensitive genic male sterile (TGMS) wheat line (Triticum aestivum L.) used in hybrid wheat breeding in northern China. BS20-T was crossed with common wheat variety ZN7. F1 plants were highly fertile. The segregation ratio of male fertile and male sterile individuals in F2 and BC1F1 plants were close to 3:1 and 1:1, respectively. Other crosses of BS20-T also segregated for a single gene. Bulked sergeant analysis with SSR markers indicated the sterility gene was located on chromosome 2BL. It was named tmsBS20T. Screening of 162 extremely sterile and 30 extremely fertile F2 plants with linked markers indicated flanking by gwm403 and gwm374 with genetic distances of 2.2 and 4.5 cM, respectively. tmsBS20T was transferred into several common wheat varieties by using traditional hybridization combined with marker assisted selection with these two markers. Further identification of derived TGMS lines is ongoing.

    ABSTRACT: Verticillium wilt, caused by Verticillium dahliae, is a soil-borne disease of the cultivated eggplant (Solanum melongena). The accession PI388846 from a wild species S. linnaeanum, shows resistance to Verticillium wilt. The introgression of its disease resistance gene into cultivated eggplants would allow for breeding disease resistant eggplants. In this study, interspecific hybridization and subsequent backcrossing between PI388846 and cultivated eggplants were performed. The results showed that Verticillium wilt resistance was successfully introduced into the cultivated eggplants, and the agronomic traits of the interspecific hybrid progeny were improved by continuous backcrossing with the cultivated eggplants. In addition, a gene specific marker for the Ve homolog in PI388846 was developed to detect Verticillium wilt resistance in the backcross population. The results represent a positive beginning for the genetic enhancement of cultivated eggplants for Verticillium wilt resistance.

    ABSTRACT: Soil waterlogging is a primary constraint to crop yield both globally and in the United States, yet little is known about the genetic control of waterlogging tolerance in wheat. The objective of this study was to characterize genetic variation for key adaptive traits influencing waterlogging tolerance at the vegetative stage and to identify associated quantitative trait loci (QTL). Traits measured included shoot and root biomass, root length, tiller number, seedling height, stem elongation, and chlorophyll content. Waterlogging reduced traits means by 8–58 % in the greenhouse and by 22–32 % in the field, with the largest reduction observed for root length. Both root biomass and root length showed significant genotype by treatment interaction indicating an adaptive growth response in waterlogged versus non-waterlogged soils and a possible mechanism of tolerance. A positive correlation was observed between chlorophyll content and shoot biomass, and between root and shoot biomass under waterlogging, which may make indirect selection possible. QTL analysis identified 48 individual QTL that clustered into 10 genomic regions consistently detected in both the greenhouse and field experiments. While most clusters were constitutively expressed, regions on chromosomes 1B and 6D were found to be adaptive to conditions of soil waterlogging, with no QTL detected in the non-waterlogged controls. A QTL region on chromosome 1D specific for chlorophyll content was significant across environments and repeated measurements, explaining up to 24 % of the phenotypic variation. This study provides the first reported QTL for waterlogging tolerance in wheat identified under both field and greenhouse conditions. The QTL can be targeted by breeders for future genetic improvement.

    ABSTRACT: The QTL analysis of dead leaf rate (DLR) and dead seedling rate (DSR) during the seedling stage under salt or alkaline stress were conducted, in order to provide the scientific basis for the fine mapping and cloning of QTLs associated with salt or alkaline tolerance, and for the salt or alkaline tolerance of SSR marker assisted rice breeding. The recombinant inbred line (RIL) population F8 including 200 lines derived from the cross “Yiai 1 × Lishuinuo” were used in the study. The DLR and DSR of RIL and its parents were evaluated under 1.5 % NaCl of salt stress and pH8.7 to pH8.9 of alkaline stress, respectively. The results showed that DLR was a quantitative trait controlled by multiple genes, and DSR was a quantitative trait controlled by a few major genes and many other minor genes together under salt stress; DLR and DSR under alkaline stress were quantitative trait controlled by multiple genes. The genetic linkage map with 155 SSR markers which overlay the whole rice genome of 1541.5 cM and with the average distance of 9.95 cM between each two markers was constructed. Seven additive QTLs and three pairs of AA epistatic QTLs associated with DLR and DSR under salt or alkaline stress were identified, Of them, qDSRs8 - 1 with LOD of 6.54 and observed phenotypic variance of 15.96 % under salt stress, and qDLRa5 - 3 with LOD of 3.51 and observed phenotypic variance of 8.32 % under alkaline stress were new detected QTLs, which can be used in the breeding program in rice to get salt or alkaline tolerance rice cultivars in the future. The results also showed that excellent gene resource could be detected from any one rice germplasm; mechanisms for salt tolerance and alkaline tolerance in rice was different; additive QTLs were closely related with the resistance to salt injured in rice but epistatic effects of AA were closely related with the resistance to alkaline injured in rice.

    ABSTRACT: Cytoplasmic male sterility is an important biological tool which is now available to pigeonpea breeders to exploit heterosis/hybrid vigor. A variety of CMS systems have been developed when wild relatives of pigeonpea from different gene pools were crossed as the female parent with cultivated types as the male parent. This paper reports a second source of CMS developed by using the cultivated pigeonpea as the female parent and one of its wild relative Cajanus lanceolatus (WV Fitgz) van der Maesen as the pollen donor, as such the A5 CMS system derived from C. acutifolius. All the F1 hybrids were evaluated to confirm hybridity using 27 simple sequence repeat (SSR) markers. SSR marker analysis of parents provided 17 polymorphic markers from a total of 27 SSR markers used. Subsequently polymorphic SSRs were used to confirm the hybridity of the F1 plants. F1 hybrid plants were crossed with a range of pigeonpea cultivars to identify maintainers of male sterility. Morphology of the F1 and backcross generations, cytology of the sterile as well as fertile floral buds derived from the crosses between sterile F1 hybrids and unrelated pigeonpea cultivars were studied. An important observation made was that male sterility was a post meiotic process. Microsporogenesis was normal until the tetrad stage, but none of them formed pollen grains. Instead, they grouped together within the pollen mother cell wall and the tetrads did not separate into individual pollen grains.
