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, straw
nitrogen uptake, productive tillers per plant, tillers per plant, nitrogen
translocation efficiency, nitrogen use 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.
