Study of resistance inheritance to BCMNV virus in common bean by generation mean analysis

This research was conducted to study the resistance inheritance of common bean to BCMNV virus. The Cross used in the experiment was between cultivars Goli (the resistant parent) and Derakhshan (the sensitive parent). Six generation seed obtain from Khomain bean national station and as randomized complete block design with four replications, planting and inoculate in plastic pot. Evaluation of plants performed with Elisa test and IC-RT-PCR 21 day after planting, and by observation at 45 day after planting. Resistance inheritance study with use of generation mean analysis, indicate that additive and dominant component have important role in control of infection rate. And simple model of additive – dominant can explain for genetic changes. Also determined that, for all traits under study, traits reduce genes are dominant and also this traits controlling genes with according to symptom and largeness are at different place. Means of broad-sense and narrow-sense heritability account 74 and 54 percent respectively. Thus selection for highest resistance can be effective. Accounting of effective factors number (genes) indicate that a great effect gene have role to genetic resistance control (probably I gene) and seem one or some small effect gene assistant to I gene for resistance induction.
