A Study on Leaf Character and Spike Grain-Leaf Ratio in Wheat

This study was conducted with 10 genotypes of winter wheat. There were significantly negative correlation between leaf area and per unit spike, and significantly positive correlations between leaf area and per spike grain, and grain weight per spike. There was significantly positive correlation between spike grain/flag leaf area ratio and grain yield, and were not significant correlations between spike grain/flag leaf area ratio and all yield components. The spike grain/flag leaf area ratio can be regarded as important criteria of selection in high-yield wheat breeding.
