Abstract:

Seventy genotypes of rice (Oryza sativa L.) were evaluated during Kharif 2014 to study the nature and extent of correlation among yield and yield attributing characters, number of tillers per plant, number of effective tillers per plant, plant height, panicle length, number of filled grains per panicle, 1000-grain weight, days to 50 per cent flowering, days to maturity, grain yield per plant. Character association studies revealed that the characters grain yield per plant showed significant positive association with plant height, number of tillers per plant, number of productive tillers per plant, number of filled grains per panicle and 1000 grain weight. This indicated that simultaneous selection of all these characters was important for yield improvement.
