Abstract

The objective of the research was to evaluate morpho-agronomic of genetic diversity in common bean landraces based in predicted genotypic values, to identify divergent genotypes with agronomic potential in several traits for selection activities and crosses in the breeding program. Traits evaluated were plant height, branches per plant, days to flowering, days to maturity, pods per plant, seeds per pod, seeds mass and grain yield at Nampula Research Station, Mozambique, in an augmented design with four blocks, 27 genotypes (24 landraces and 3 checks). Data were subjected to analysis of deviance, variance components and genetic parameters. The genotypic values were estimated by REML/BLUP mixed model and were used in heat map clustering, pairwise distances and constellation plot. The results indicated genetic variability for all traits except branches per plant and showed six clusters of divergent genotypes. Days to flowering, pods per plant and plant height, had the highest contribution to genetic divergence. The morpho-agronomic analysis of genetic diversity in common bean landraces based in predicted genotypic values allowed to identify divergent genotypes with agronomic potential in several traits for selection activities and crosses in the breeding program
