Article: Segregation and selection of observed yardlong bean (Vigna sesquipedalis L. fruwirth) to get expected lines of purple pod[show abstract] [hide abstract]
ABSTRACT: The previous practical breeding on yardlong bean was gotten potential lines in purple pod, namely UBPU1, UBPU2 and UBPU, respectively. This purple colour, indicated anthocyanine compound in fresh pod, and it was role-play as antioxidant in human life. These lines had potential properties to be developed as prospective and new varieties. The segregated or expected lines had 1200 ones and it had gotten from previous practical segregation. These lines had a high variability in purple colour and quantitative characters. Mass selection method had applied to evaluate pod colour, length, surface and taste. Purple colour of pod was identified by RHS colour chart. There was high variability on observed qualitative and quantitative characters. All of them described a genetic variability. Variability of pod purple colour distributed from Deep Purplish Red (colour code: 95B), Dark Purple (colour code: 79A), Dark Purple Green Strip (colour code: 79B), Strong Red (colour code: 46A), Deep Red (colour code: 53A), and Dark Red (colour code: 59A), respectively. Although pod and stem were purple, but had variability of purple colour. This breeding had gotten 90 expected lines of purple yardlong bean and was evaluated their yield potential. It was gotten 15 candidates of new varieties. Keywords: Yardlong bean, purple pod, selection, linesInternational Research Journal of Agricultural Science and Soil Science. 03/2013; 3(3):88-92.

ABSTRACT: The research objective was to select wheat genotypes that can adapt on the medium and low plains. Twenty-seven genotypes and three varieties of wheat were grown in four locations in the medium and low plains since June-October 2009. The experiments were arranged using a randomized complete block design repeated three times. Analysis of variance performed at each location followed by a test of homogeneity of error range, the combined analysis of variance and yields stability analysis. Genotype x environment interaction significantly affecting yield. Stable genotypes and widely adaptable across locations were G-1 (1.94 t.ha-1), G-20 (1.24 t.ha-1), H-14 (1.85 t.ha-1), H-19 (1.59 t.ha-1), H-20 (1.69 t.ha-1), H-21 (1.48 t.ha-1), 162 (1.62 t.ha-1), 80 (1.63 t.ha-1), 82 (1.78 t.ha-1), 91 (1.49 t.ha-1), and 142 (1.45 t.ha-1). Genotypes adapted in productive environment were G-18 (1.23 t.ha-1), G-19 (1.63 t.ha-1), 185 (1.30 t.ha-1), 40 (1.33 t.ha-1) and 42 (1.52 t.ha-1). Genotypes adapted in marginal environments were 28 (2,22 t.ha-1), H-1 (1.61 t.ha- 1), H-8 (1.65 t.ha-1) and H-16 (1.68 t.ha-1). Genotype was selected as an improvement material in the wheat breeding in medium and lowland of tropical regions.

ABSTRACT: The adaptation trial was applied to determine the benefits of genotype-environmental inter-action, adaptability and stability of lines. The previous research successfully obtained 8 UB lines which had high yield and tolerant to aphids. These lines belong to plant breeding laboratory of Brawijaya University, which had stability and a high potential can be immediately released to the public. Research was conducted in 2010, dry and rainy season, on 3 locations of yardlong bean, namely Malang, Kediri and Jombang. Randomized Block Design was applied in these locations.Genotype-environment interaction was analyzed with combined analysis of nested design.The adaptability and stability were known from regression analysis based on the stability of Eberhart and Russel. There were 6 stabile lines, namely UB7070P1, UB24089X1, UB606572, UB61318, UB7023J44, and UB715, respectively. They were recommended to be released as new varieties which had pest tolerance and high yield. The UBPU was suitable to be developed in marginal land. The 6 new varieties had registered to Agriculture Department Republic of Indonesia, namely, Brawijaya 1, Brawijaya 3, Brawijaya 4, Bagong 2, Bagong 3 dan Bagong Ungu, respectively.

ABSTRACT: Open pollinated maize and two check varieties were evaluated in four locations, i.e. Malang, Jombang, Kediri, and Trenggalek regencies for two seasons from March to November 2009. The research objective was to determine stability and adaptability of the open pollinated maize. The experiment was conducted using a randomized complete block design. The treatment had nine lines, i.e. UB4101, UB3101, UB4201, UB7201, UB4202, UB3301, UB4301, UB7301, UB3302 and two check varieties, Bisma and Arjuna. The treatment was repeated three times. Percentage point of variance ratio was applied to determine homogeneity error. Variance analysis of combined experiment was conducted to determine genotype x environment interaction. Yield stability and adaptability were analyzed using Eberhart and Russell linear models. There was genotype x season x location interactions on maize yield. It mean that there were population yield performance changes at different environments. There were four populations have stability point, i.e. UB4101 (5.5 t ha -1), UB3301 (5.7 t ha -1), UB7301 (5.7 t ha -1), and UB3302 (5.4 t ha -1). Population UB4201 (5.1 t ha -1) was adaptable to productive environment, and UB4301 (5.8 t ha -1) was adaptable to marginal ones.

ABSTRACT: Yardlong bean breeding at Plant Breeding Laboratory, Faculty of Agriculture, University of Brawijaya has been successfully establishing yardlong bean lines tolerant to aphid. The Yardlong bean lines is still need to be tested for yield. The experiment was conducted with a total of one hundred and twenty yardlong bean lines and three checks yardlong bean cultivars. Since the high number of test entries and limited amount of seed available in early stage breeding program, the test entries lines were planted without replication while checks cultivars were replicated in all blocks adopting the augmented experimental design. The field plot consist of eight blocks. In every blocks was sown differ randomized fifthteen lines and three cultivars. The susceptible genotype to aphid is planting two weeks before research to attract aphid as borders. The data were subjected to statistical analysis for augmented experimental design. Observations made to aphids attack intensityy, flowering day, pod number, pod length, pod diameter, number of seeds per pod, weight per pod, pod weight per plant and 100 seed weight. There was genetic variability among the yardlong bean lines, so that the selection can be done. Multivariate analysis based on yield and yield component the lines can be grouped into three different genetic groups. The trial obtained 12 lines that have the potential to adaptation trial, namely UB7070, UB7064, UB7022, UB7023, UB7068, UB7074, UB7073, UB7037, UB7017, UB7055, UB7054, UB7109.
