Abstract:
A study was conducted to evaluate the genetic variability parameters, correlation and path coefficient analysis for yield and yield related, floral and grain quality traits in twenty- nine rice maintainer lines at Rice Research Centre, ARI, Hyderabad during rabi, 2020-21. The results indicated that stigma length, number of grains per panicle, gel consistency, 1000-grain and grain yield per plant showed high PCV and GCV. High heritability coupled with high genetic advance as per cent of mean was observed for days to 50% flowering, stigma length, stigma exsertion, plant height, number of grains per panicle, 1000-grain weight, kernel length, kernel breadth, kernel L/B, amylose content, gel consistency and kernel length after cooking which indicates simple selection would be effective for enhancement of these traits. Correlation studies indicated that grain yield per plant showed significant and positive association with amylose content, plant height, panicle length, number of grains per panicle, number of productive tillers per plant and angle of flower opening. High positive direct effect on grain yield per plant was recorded by kernel breadth, amylose content, plant height, number of productive tillers per plant and stigma length.
