Abstract

                                An investigation was carried out on variability, correlation and path analysis for ten characters of pigeonpea germplasm lines raised during kharif 2010-11. Days to 50 per cent flowering, days to maturity and plant height showed low coefficient of variation and low genetic advance as percent of mean. Number of secondary branches per plant and number of pods per pant showed high coefficient of variation along with high heritability estimates. Days to 50 per cent flowering, days to maturity, number of primary branches per plant and number of secondary branches per plant showed positive and significant correlation with number of pods per plant both at phenotypic and genotypic levels. Number of primary branches per plant showed positive significant association while, plant height and pod damage percentage showed negative significant association with seed yield. Path analysis revealed that days to 50 per cent flowering, number of primary branches per plant and number of pods per plant exerted positive direct effect on seed yield.
