Abstract
The present study aims to estimate the genetic parameters of seven yield-attributing traits to assess genetic variability and correlation of yield and yield-related traits in land races of rice. High heritability estimates coupled with high genetic advance were recorded for plant height, ear bearing tillers per plant, number of f illed grains per panicle and test weight indicating that direct selection of these characters would be more accurate for yield improvement. The results of correlation and path coefficient analysis revealed that the traits viz., days to 50 % flowering, number of filled grains per panicle and test weight exhibited positive association along with high positive direct effects both at genotypic and phenotypic levels. Hence direct selection for these traits will simultaneously improve both the traits.
