ABSTRACT
The present study was undertaken with the objective to determine the degree of association between yield and it`s component characters in rice (Oryza sativaL.). Forty F1 crosses of rice were evaluated during Kharif 2015 to study the nature and extent of correlation among yield and yield attributing characters, days to 50 per cent flowering, days to maturity, plant height, number of total tillers per plant, number of productive tillers per plant, panicle length, number of filled grains per panicle, spikelet fertility, biomass, harvest index, 1000-grain weight, grain yield per plant. The results revealed that grain yield per plant to be positively and significantly associated with days to maturity, number of productive tillers per plant, plant height and kernel length indicating importance of these traits as selection criteria in yield improvement programmes.
Key words: Rice (Oryza sativa L.), Yield components and Correlation.
