Genetic parameters and association analysis for grain yield and yield attributing traits in rice (Oryza sativa L.) germplasm lines

The intensity of trait association and genetic variability yield attributing variables in 217 rice genotypes was investigated during kharif 2018. existence among the demonstrated by analysis variance, which recorded significant differences for all seven studied parameters. estimation indicated that full grain number per panicle (37.2 % 34.1 %) & single plant (24.7 20.55 had highest phenotypic coefficients variation (PCV) genotypic ( GCV), High heritability along with high advance as a cent mean (GAM) found Plant height (98.9 20.8 %), (95.4 36 length(96.8 35.9 panicle(99.5 61.6 thousand seed weight (98.1 40.25 (69.2 35.2 , depicting additive gene action inheritance these A simple selection procedure can help to enhance characteristics even further. Correlation regression coefficient findings (0.193**) (0.177**) impact on yield. (0.265**), followed (0.194**) (0.110**), maximum direct positive effect yield, path analysis. As result, accessions higher panicle, would be suitable enhancement programme.
