Genetic Divergence and Selection of Genitors Aiming to Generate Variability in Common Bean Lines

The objective of this work was to evaluate the genetic divergence between common bean strains from breeding program Agricultural Research Institute Mozambique (IIAM)-Zonal Centre (CZC) and identify potential genitors generate segregating populations with high average wide variability. Five lines were evaluated in a randomized block design three repetitions. quantitative traits leaf area index, days 50% flowering, maturity, several pods per plant, 100 seed weight, yield, while qualitative growth habit, epicotyl colour, colour intensity, roughness, fresh pod grain size, flower colour. data obtained submitted variance analysis grouping means by Scott-Knott test. relative importance characters Singh. Clustering performed Tocher optimization method distance projection 2D plane, using generalized Mahalanobis as measure dissimilarity. degree preservation distances plane assessed Cohenetic Correlation Coefficient, distortion, stress. LPA54 Bonus highlighted direct selection based on performance se their characteristics. Genetic variability checked for trait’s flowering 100-seed weight separated into two groups. crosses (G19833, LPA54, Manteiga, Bonus) strain DOR364 there is obtaining hybrids higher heterotic effect size most important discrimination
