Assessment of genetic variability, heritability and genetic gain for agro-morphological traits in lentil (Lens culinaris Medik.)

Abstract

This study was conducted at the N.E. Borlaug Crop Research Centre, G.B. Pant University of Agriculture and Technology, Pantnagar, India, during the rabi seasons of 2024-2025, to study the agro-morphological, genetic variability, heritability, expected genetic advance and inter-relationship of ten yield attributing traits for 50 genotypes. The genotypes showed highly significant (p75%) was recorded for seed yield, harvest index, and seeds per pod. Traits such as seed yield, harvest index, and biological yield exhibited both high heritability and high genetic advance as a percentage of mean. These results point towards the presence of additive gene effects influencing the inheritance of these traits, highlighting the efficacy of simple selection methods for yield enhancing focusing on these essential agronomic characteristics.
