Association coefficient analysis in grain amaranth (Amaranthus hypochondriacus L.)

Abstract

18 germplasm accessions of grain amaranth (Amaranthus hypochondriacus L.) were carried out to estimate the estimate the association analysis among traits during rabi 2015-16 at research farm of IGKV, Raipur (C.G.) Seed yield / plant showed the highest significant positive association with panicle width, number of leaves /plant and number of panicles / plant. Grain weight /panicle was found to significant but negative association with number of leaves/ plant. Hence, direct selection for these traits may be advantageous for selecting the high yielding genotypes in the available germplasm accessions of grain amaranth.
