Study about Correlation and Path Analysis in Grain Amaranth (Amaranthus hypochondriacus L.)

Twenty six genotypes of grain amaranth were evaluated during rabi 2017-18 for assessing the correlation and path coefficient analysis for grain yield and its components. The grain yield per plant was found to be positively and significantly associated with plant height, panicle length, dry weight of leaves, dry weight of panicles, biological yield/plant and harvest index. Dry weight of panicles had highest path towards grain yield per plant, dry weight of leaves directly associated with days to maturity and plant height. This indicates that these characters played an important role in higher grain yield in grain amaranth.
