Genetic variability studies in pigeonpea

Abstract

Fourty two genotypes were evaluated for variability, heritability and genetic advance during 2023 at College of Agriculture, Badnapur. The analysis of variance showed significant differences among the genotypes for all the characters studied, indicating that there was high variability among the genotypes. Grain yield (t ha-1) has exhibited high genotypic and phenotypic coefficient of variation, thus indicates that this character is governed by genetic factors and possible improvement through selection. Whereas, 100 seed weight (g), Number of pods/ Plant, Number of secondary branches/ Plant and Number of primary branches/ Plant obtained moderate estimate at both level. High heritability showed at character and high genetic advance showed at characters Number of pods/ Plant, Seed yield /Plant, 100 seed weight (g), Number of secondary branches/ Plant and Plant Height (cm). This indicates that the heritability was due to additive gene effects and selection would be promising for these characters.
