were
positively correlated with grain yield. All the parameters showed a positive correlation with economic yield under red light
condition. Under low light condition, HI (0.991*) had a significant positive correlation with grain yield. Panicle length(0.466), spikelet per panicle (0.377), well filled grain per panicle (0.478), HD grain weight (0.255) and TDMP (0.412) had
positive correlation with grain yield. Low light maintained negative correlation of Panicle/m2
area (-0.314) with grain yield.
