Abstract:
During kharif 2018, one hundred thirty (Oryza sativa L.) RILs derived from a cross between Basmati 370 and Pusa basmati1121 were evaluated for fifteen quantitative traits related to grain quality and yield to examine the nature and magnitude of genetic variability, correlation coefficient analysis and genetic advance. Estimates of correlation coefficient, genetic variability, heritability and genetic advance in per cent of mean were also obtained for the above fifteen traits. Analysis of variance revealed that significant amount of genetic variability was present in the entire characters studied. The highest positive correlation was observed between PL and PH (r=0.33), ET and PH (r=0.21) followed by GW and GPP (r=0.20). Some of the traits showed then significant negative correlation with each other like YPP and PL (r=-0.25), KE and GW(r=-0.02) and KE and YPP (r=-0.11). High phenotypic variation was observed for yield per plant (40.25%), effective tillers per plant (42.28%) and amylose content (37.41%), Moderate phenotypic variations was recorded in plant height (12.23%), panicle length (11.99%) and so many other traits. Therefore, the present study was undertaken to find the genetic variability, correlation coefficient analysis, genetic advance through RIL population for the Selection criteria of fine rice lines.
