Experiment was carried out to bring out the genotypic variations from a broad genetic base and to utilise the best attribute in achieving higher grain yields. The results indicated significant genotypic differences in yield attributes and yield. The association analysis showed a significant positive relationship of grain yield with productive tillers, filled grain number per panicle, 1000 grain weight and harvest index. Among the yield attributes productive tillers, filled grain number per panicle and harvest index contributed to a greater extent in achieving the productivity. This indicates, the selection of numerically high value for each yield attribute and incorporating in a single genotype may boost the grain yields significantly to a higher level. However, grain size is not a preferable character in consumer point of view. Therefore, selection of genotypes with large number of productive tillers and filled grain per panicle may be worthwhile.
