Association between yield and yield attributes in short duration pigeonpea hybrids

摘要

Significant differences were observed among pigeonpea hybrids for all the traits except number of seeds pod~(-1) in both the years of experiment. Significant genotypic correlations of seed yield plot~(-1) with days to initial flowering and maturity,height of the plant at initial flowering and at maturity, number of primary branches and pods plant~(-1) and seeds pod~(-1) Phenotypic correlations of seed yield plot~(-1) with days to maturity were found significant in the first year experiment, whereas, in the second year experiment seed yield plot~(-1) showed significant genotypic correlations with days to initial flowering, plant height at maturity, number of primary branches and pods plant~(-1). However, none of the characters showed significant phenotypic correlations with seed yield plot~(-1). Harvest index showed significant and negative genotypic correlations with days to initial flowering and maturity, primary branches and pods plant~(-1), seeds pod~(-1) and 100-seed mass.
