Identification of superior progenies between common bean gene groups for root system obtained by recurrent selection

Genetic variability is essential for gains in breeding programs. The cyclic process of progeny recombination a strategy to raise the chances selecting better genotype combinations. objective this study was identify superior progenies between common bean genes groups first recurrent selection cycle root system traits. Parents Andean and Middle American gene were hybridized complete diallel scheme. Thereafter, parents F1 F2 populations planted field. To establish base population (C0), seven segregating (F2) with performance selected intercrossed, resulting recombinant (C1). estimate gain, C0 C1 genotypes compared regard following variables: total length (TRL, cm), projected area (PRA, cm2), volume (VOL, cm3) number tips (RT). difference combinations indicates presence genetic effectiveness selection. mean progress system-related traits 12.9% (TRL), 12.6% (PRA), 12% (VOL) 11.5% (RT) cycle. phenotypic exceeded that their all These are promising as next
