Abstract

In order to evaluate heritability and gene action for resistance to Bean common mosaic virus (BCMV) four crosses were established among bean genotypes with various resistance to BCMV. All four crosses were extended by other generations-F1, F2, backcrosses- to establish four families. Four separate experiments were conducted in RCB design with 3 replications in greenhouse conditions. Inoculation was accomplished 2 weeks after sowing and sampling for ELISA test were performed 3 weeks after inoculation. Studies on the inheritance of resistance to BCMV using generation mean analysis and generation variance analysis indicated that additive components and epistasis([i], [l]) play a major role in these crosses. Also, average broadsense and narrowsense heritabilities were 0.77 and 0.64 respectively. These data were showed importance of additive components for this trait. Therefore, selection for high resistance in breeding projects about this trait could be effective.

Key words: Bean, Bean common mosaic virus, Generation mean analysis.
