Abstract:
In the present study, correlation and path coefficient analysis carried out for eleven yield and yield contributing traits in 30 germplasm accession of grain amaranth received from NBPGR-New Delhi raised in RBD with 2 replications at experimental research farm, Department of Agril. Botany, VNMKV, Parbhani. during rabi 2022-23. In present investigation grain yield per plant has recorded the significant and positive association with days to 50% flowering, days to maturity, plant height, number of spikelets per inflorescence, inflorescence length (cm), inflorescence girth (cm), stem girth (cm), and leaf area per plant (cm2) at both genotypic and phenotypic level. However, negative significant association with 50 ml volume weight (g) and harvest index (%). While, in path analysis, the trait inflorescence girth (0.712) have exerted highest positive direct effect on grain yield followed by inflorescence length (0.213), days to 50 percent flowering (0.156), plant height (0.115), number of spikelets per inflorescence (0.105) and 50 ml volume wt. (0.064) at genotypic level. Whereas, days to maturity (-0.067) exerted highest negative direct effect on grain yield at genotypic level. At phenotypic level, the result of path analysis shown that, the trait inflorescence girth (0.568) have contributed highest positive direct effect on grain yield followed by plant height (0.183), inflorescence length (0.146), days to 50 percent flowering (0.135), leaf area per plant (0.130) and number of spikelets per inflorescence (0.087). Itclearly indicates that direct selection would be fruitful based on these characters to increase in grain yield per plant.
