Abstract

A total of 10 mungbean (Vigna radiata (L.) Wilczek) genotipes including check variety (Vima) were evaluated on rainfed after rice at Ngale Experimental Farm, Ngawi, East Java during early dry season of 2010. The experiment was conducted in randomized complete block design with three replications. Plot size was 4 m x 5 m, plant spacing was 40 cm x 20 cm, each hill contained two plants. A correlated and path coefficient analyses were used in order to determine the association among characters and quantify the direct and indirect effects of agronomy traits on seed yield. The study has identified 2 promising lines, i.e. MMC342d-3-4 and MMC342d-kp-3-3 produced the highest yield of 2.2 t and 2.0 t/ha respectively and had good adaptation on rainfed. Two varieties (Kutilang and Kenari) having large seed size (>7.5g/100 seed). Therefore, these varieties can be used as source of parents on breeding program. Among the agronomic characters, number of pods per plant, number of seeds per pod and seed size were positively and significantly correlated with grain yield. The direct effect of number of pods per plant, number of seed per pod and seed size to grain yield as indicated by path coefficient were the highest, while other causal effects to grain yield were small or negative. Based on both analyses, mungbean genotipes with high grain yield should have high number of pods per plant, number of seeds per pod and large seed size. Therefore, number of pods per plant, number of seeds per pod and seed size can be suggested for selection criteria in selecting high yield mungbean genotipes on rainfed.

Abstract

The F2 progenies of two crosses among three mungbean varieties were evaluated with their parents (Varsha, Park it and Local Belu)at Muara Experimental Station, Bogor during dry season of 2007. The experiment was conducted in a randomized complete block design with three replications. The seed of each F2 progenies and parents were planted in four rows of four meters long.Plant spacing was 40 x 20 cm, each will contained one plant. Among the character studies, days to maturity, seed yield per plant and plant height had the highest coefficient of variability, with the mean of 51.3%, 49.8%, and 49.2% respectively.Number of branches, pod length and number of seed per pod had the lowest coefficient of variability, and the mean were 19.1%, 18.8%, and 17.6%.The heritability estimates of nine agronomic characters studied ranged from IS.6 to 65.2%. Plant height and number of pods per planthad the highest heritability estimates with mean of 65.2% and 58.6% respectively for the two crosses. The mean heritabilityestimate for seeds yield per plant, pod length and number of seeds per pod were the lowest of 19.4%, 18.3% and 15.6% respectively. Based on the F2 data, selection of plant height and days to maturity had the highest expected genetic advance of 45.8 and 41.0%.The mean expected genetic advance for pod length and number of seeds per pod were the lowest of 19.4 and 17.4%.Correlation coefficient between grain yield with plant height, number of pods per plant and seed size were positively significant (r = 0.404, 0.613 and 0.422 respectively). Correlation coefficient between grain yield with other agronomic characters were small or negative. Therefore, plant height, number of pods per plant and seed size can be used as the selection criteria in selecting mungbean genotypes for high yield.

Abstract

A total of 27 soybean {Glycine max (L.) Merrill} genotypes including check variety (Kawi) were evaluated on dry land at Ngale Experimental Farm, Ngawi, East Java during early rainy season of 2009/2010. The experiment was conducted in a randomized complete block design with three replications. Plot size was 4 m x 5 m, plant spacing was 40cmx20cm, each hill contained two plants. A correlation and path coefficient analyses were used in order to determine the association among characters and quantify the direct and indirect effects of agronomic traits on seed yield. The study has identified 3 varieties, i.e. Kaba, Wilis and Tanggamus produced the highest yield (>1.6 t/ha) and had good adaptation on dry land. Two varieties (Grobogan and Argomulyo) having large seed size (>15 g/100 seeds), and four varieties,i.e. Tidar, Grobogan, Gepak Ijo and SHR-W60 had early maturity (81days). Therefore, these varieties can be used as source of parents on breeding program. Among the agronomic characters, plant height, number of pods per plant and harvest index were positively and significantly correlated with grain yield. The direct effect of plant height, number of pods per plant and harvest index to grain yield as indicated by path coefficient were the highest, while other causal effects to grain yield were small or negative. Based on both analyses, soybean genotypes with high grain yield should have sufficient plant height, high number of pods per plant and high harvest index. Therefore, plant height, number of pods per plant and harvest index can be suggested for selection criteria in selecting high yield soybean genotypes on dry land.
