Grain Zinc and Iron Association Studies in Swarna X Type 3 RIL Population of Rice

The present study was undertaken with the objective to determine the degree of association between yield, yield attributing traits and grain Zinc and Iron concentration in Swarna x Type 3 RIL population of rice. 100 RIL population were evaluated for identifying their efficiency with respect to ten characters. The correlation studies revealed that grain yield per plant showed strong positive significant association with plant height and 1000- seed weight. Positive non- significant association of grain yield per plant was observed with days to 50 per cent flowering, panicle length, number of filled grains per panicle and significant negative correlation was observed for grain iron and zinc concentration
