Abstract
The present study was conducted at the College of Agriculture Raipur, IGKVV, and Chhattisgarh. The experimental materials used 103 local landraces of pigeonpea, including three popular standard checks during Kharif 2019-20 in an augmented RBD Design for 15 qualitative and 20 qualitative characters observations recorded and analysis of variance for showed differences for different characters. High magnitude of the coefficient of variation GCV % and PC V% (more than 20 %) in some genotypes was observed for Duration of flowering (20.96, 21.41), Harvest Index (22.21, 22.82), Maruca vitrata larvae population (22.58, 22.77), No of Secondary branches (23.17, 23.33) while shelling percentages are low 8.64 and 9.11, respectively, rest all traits are in a medium value. Result of major pigeonpea insect's incidence 103 genotypes tested against different insect pests, 10 genotypes recorded most promising entries against key pest and 10 genotypes were recorded most susceptible entries against insect pest. A high coefficient of variation in the entire genotypes was observed for some traits.
