The varieties differed and dry weight in the leaf area and dry weight of fully expanded flag leaf, total leaf area of plants at 50% anthesis, number of total tillers (m-2), number of fertile tillers (m-2), number of spikelets per spike, 1000-grain weight, grain yield, straw yield and harvest index. There was significant positive correlation (r= 0.712), between flag leaf area and flag leaf weight. Flag leaf area showed negative correlation (-0.556) with the number of spikelets per spike. Flag leaf area showed positive correlation (0.570) with the 1000-grain weight. Flag leaf area had no significant effect on grain yield. Plant leaf area showed positive correlation with the total number of tillers (m-2) and the spike length r = 0.518 and r = 0.552, respectively. Positive correlation (0.671) was observed between the total number of fertile tillers as (m-2) and he grain yield (r = 0.700). The number of grains per spike showed a correlation (r = .546) with he straw yield.
