Genetic Variability on Seed Yield and Related Traits of Elite Faba Bean (Vicia faba L.) Genotypes

Million Fikreselassie and Habtamu Seboka

Abstract:
Faba bean is one of the most important cool season crops in the highlands of Ethiopia and the country is considered as the secondary center of diversity. This study was conducted at Haramaya, Boreda and Hirna districts of Eastern Hararghe from 2006 to 2008 cropping season using twenty five elite genotypes of faba bean to determine the extent and pattern of genetic diversity for seed yield and related traits. The treatments were arranged in a randomized complete block design with three replications. The data were subjected to the analyses of variance using the SAS program. The mean squares due to genotypes were highly significant for seed yield (p<0.01) indicating the existence of sufficient genetic variability for seed yield. Mean squares due to the interaction between year and location were highly significant for all the traits studied (p<0.01). High genotypic coefficient of variation (10093.53%) was observed for seed yield followed by number of seeds per plant (325.45%). The estimated values of phenotypic variances were in the range of 0.60 for number of seeds per pods to 196564.64 for seed yield. Genetic gains that expected from selecting the top 5% of the genotypes, as a percent of the mean, varied from 12.32% for number of seeds per plant to 35.46% for seed yield. The average linkage technique of clustering produced a more understandable portrayal of the 25 faba bean genotypes by grouping them into five clusters. The maximum distance was found between cluster three and five (D2 = 691.47). Thus, the materials tested in the entire experiment will be maintained for further breeding program.
