| Abstract: | The grain-leaf area ratio and its correlation with the yield trait of 12 high-yield wheat cultivars with different spike types broadly planted in Henan province were measured under close planting conditions in this study.The results showed that there was significant difference in the grain-leaf ratio among multi-spike wheat cultivars,mid-spike wheat cultivars and big-spike wheat cultivars.The ratio of spike grain weight to flag leaf area(SGW/FLA) and grain number per spike to flag leaf area(GNPS/FLA) were p... |
