Abstract
The present investigation was conducted at Agricultural College and
Research Institute, Madurai, under nitrogen-starved conditions. The
experimental material comprised 245 recombinant inbred populations (RILs) of
ASD 16 X Basmati 370 cross, which were laid out in randomized complete block
design with two replications. Observations were recorded for eighteen
quantitative characters including grain yield per plant. Correlation studies
revealed that grain yield per plant was positively and significantly correlated
with grain nitrogen uptake, total nitrogen uptake, dry matter production,
productive tillers per plant, productive tillers per plant, tillers per plant,
straw nitrogen uptake, straw nitrogen content, nitrogen translocation
efficiency, 100 grain weight, grains per panicle and plant height. Whereas,
negatively and significantly correlated with days to 50% flowering. These
results indicated the inherent relationship of these characteristics with grain
yield per plant. Hence these characters are best considered for yield
improvement of recombinant inbred population of rice.
