Genetic parameters and selection of black bean lines for resistance to fusarium wilt and yield
Abstract The objective of this work was to estimate genetic and phenotypic parameters of black bean (Phaseolus vulgaris) lines for reaction to fusarium wilt (RFW), yield, and 100-seed weight (100SW) under conditions of a field naturally infested by Fusarium oxysporum f. sp. phaseoli, as well as to s...

| description | Abstract The objective of this work was to estimate genetic and phenotypic parameters of black bean (Phaseolus vulgaris) lines for reaction to fusarium wilt (RFW), yield, and 100-seed weight (100SW) under conditions of a field naturally infested by Fusarium oxysporum f. sp. phaseoli, as well as to select lines that combine the desirable phenotypes for the three traits simultaneously. For this, 116 lines obtained from two segregating populations and five check cultivars were evaluated using an 11×11 triple lattice experimental design, in the winter crop seasons of 2015 and 2016, with sowing in May. The obtained heritability estimates were high: 91, 75, and 92% for RFW, yield, and 100SW, respectively. Significant genetic correlations of -0.93 were detected between RFW and yield and of -0.28 between RFW and 100SW, indicating that more resistant lines have a higher yield and a larger grain size. Direct selection for each trait led to increases of 34% in resistance to FW, 11% in yield, and 9.0% in 100SW. Simultaneous selection for the three traits led to high gains of 22.1% for RFW, 6.6% for yield, and 7.7% for 100SW. Therefore, there is genetic variability and a high possibility of success from selection. Five lines – CNFP 19237, CNFP 19346, CNFP 19320, CNFP 19291, and CNFP 19306 – show a higher genetic potential. |
