Genetic divergence for yield and its component traits in cultivated Microsperma lentils (Lens culinaris med.)
Abstract
Forty one genotypes of lentil belonging to microsperma group of Lens culinaris were grouped into six clusters following non-hierarchical Euclidean cluster analysis utilizing data on a set of eleven characters related to yield and its contributing traits, Number of pods and seeds and leaves per plant, grain yield and biological yields per plant and harvest index were mainly responsible for the genetic divergence. Based on statistical distance and cluster mean values, five genotypes namely LL-19, LL-61, LL-117 and PL-7712 (from cluster IV) and K80 (from cluster V) were found to be most promising and hence, these genotypes may be used in future hybridization programmes to evolve desirable segregants.
