Abstract

A study conducted with twenty one diverse genotypes of grain amaranth indicated that grain yield/plant (0.546) exhibited highest positive direct effect on protein content followed by days to flowering (0.478), days to maturity (0.397), grain weight/panicle (0.388), plant height (0.377) and number of panicles/plant (0.294) whereas panicle width (−0.346), number of leaves/plant (−0.152),1000-seed weight (−0.096) and panicle length (−0.089) had negative but significant direct effect on protein content. Therefore the traits grain yield/plant, days to flowering, days to maturity, grain weight/panicle, plant height and number of panicles/plant could be selected for increasing protein content in grain amaranth.
