Abstract:
Nitrogen deficiency is more pronounced in rice especially in the upland aerobic soils. Compensating rice cultivars with Nitrogen Use Efficiency traits would require identifying the component traits involved and the level of dependence between these traits, in the present study 204 Bengal Assam Aus Panel rice lines were used for studying their response under low nitrogen soil status. It was found that the traits like chlorophyll index and days to 50% flowering were the most influenced trait under low nitrogen. There was high correlation of grain yield per plant with flag leaf width, panicle number and days to 50% flowering. The highest contribution was from the trait flag leaf width and panicle length.
