Abstract:

Genetic parameters for yield and its attributes in pigeon pea were estimated in a trial conducted during Kharif 2019 with 23 genotypes of pigeon pea. Genotypes were obtained from S.D.A.U., Sardarkrushinagar, JAU, Junagadh, NAU, Navsari and AAU, Vadodara for evaluation of nine characters related to yield. Low, moderate, and high genotypic and phenotypic coefficients of variations were observed. High genotypic and phenotypic coefficients of variations were expressed by seed yield kg/ha, the number of seeds per pod, pod length, and the number of pods per plant. High heritability coupled with high genetic advancement was observed in the traits such as days to flowering, the number of seeds per pod, pod length, seed yield kg/ha, test weight, and plant height. Based on the obtained results, the selection may be effective for these variable characters. Character association for studied traits indicated that the number of pods per plant, days to flowering, and days to maturity are strongly associated with the seed yield. Hence, due emphasis should be given to the number of pods per plant for the improvement of seed yield in pigeon pea.
