Combining ability for resistance to Fusarium wilt and yield in black bean

Abstract The objective of this work was to investigate the genetic control black bean (Phaseolus vulgaris) and select parents segregating populations with high resistance Fusarium wilt, yield, greater 100-seed weight (100SW), using a partial diallel cross. Twenty-five were obtained from two groups – first five resistant second susceptible wilt. evaluated in experiments three years/generations for reaction 100SW an area naturally infested pathogen. analysis showed additive nonadditive effects studied traits, predominance effects. CNFP 15194, 15207, 'BRS Esplendor' are genotypes negative general combining ability estimates (gi = -0.59, -0.76, -0.13, respectively), being recommended use as Among them, 15194 also forms 0.69). BRS FP403 cultivar is parent increase yield 218) 1.46). Six selected obtain lines that combine 100SW.
