Variability, character association and path analysis for yield and yield attributes in pigeonpea
The present investigation was undertaken with an objective to study the variability, heritability, character association and path analysis in 49 genotypes of pigeonpea. Number of secondary branches per plant, number of pods per plant, seed yield per plant, phenol content, 100 seed weight and number...

| description | The present investigation was undertaken with an objective to study the variability, heritability, character association and path analysis in 49 genotypes of pigeonpea. Number of secondary branches per plant, number of pods per plant, seed yield per plant, phenol content, 100 seed weight and number of primary branches per plant showed higher estimates of phenotypic and genotypic coefficient of variation. High heritability with high genetic advance as per cent of mean recorded for all the characters except protein content, days to 50 per cent flowering and days to maturity. Character association studies revealed the strong positive association of seed yield with number of pods per plant, number of secondary branches per plant, number of primary branches per plant and plant height. Path analysis indicated high positive direct effect of pods per plant on seed yield. |
