Abstract
Hundred Genotypes of fababean were evaluated for eight yield and its component
traits at research area of MAUUP (Medicinal Aromatic and Under Utillized Plants) section,
Department of Plant Breeding, CCS Haryana Agricultural University, Hisar. All the
genotypes have significant genetic variability. Characters seed yield per plant, pods per plant,
pods per plant, clusters per plant and plant height traits exhibited high variability, while other
traits exhibited moderate variability. Seed yield per plant exhibited positive and significant
correlation with plant height, branches per plant, clusters per plant, pods per plant and
100-seed weight. Path coefficient analysis revealed that pods per plant followed by clusters
per plant, branches per plant, plant height, 100-seed weight and pod length were main
contributor towards seed yield per plant.
Following non-hierarchical Euclidean cluster analysis all the 100 genotypes were
grouped into 8 clusters with variable number of genotypes. On the basis of data on genetic
divergence and mean performance of metric traits, nine diverse and superior genotypes
namely RED MUTANT-2, HB-7, IC-331571, IC-243634, HB-45, EC-5873, EC-251014,
HB-38 were identified as promising for most of the traits traits. Therefore, these genotypes
may be involved in a multiple crossing programme to recover transgressive segregants for the
further improvement of fababean.
