Abstract:
An experiment was carried out in the experimental field located at Regional Agricultural Research station, Lam, Acharya N G Ranga Agricultural University, Lam, A.P. Study was conducted on Genetic variability, character association and path analysis between yield and its contributing traits with seventeen Pigeonpea [Cajanus cajan (L.) Mill sp.] genotypes. Analysis of variance revealed that existence of significant differences among genotypes for all characters studied. The magnitude of PCV and GCV was moderate to high for number of pods per plant, number of primary branches per plant and yield. High heritability was recorded for test weight, days to maturity, days to 50% flowering, and number of pods per plant. High heritability combined with high genetic advance was recorded for test weight, yield and days to 50% flowering, indicating that these characters are controlled by additive gene effect and phenotypic selection of these characters would be effective for further breeding purpose. Yield was positively correlated with Plant height, number of primary branches per plant and number of pods per plant.
