摘　　要：为提高育种预见性和选择效率,对小麦粒叶比的概念、遗传特性、与产量因素及产量的关系等问题进行了探讨。认为粒叶比不仅是衡量小麦群体库源流协调和单位叶面积光合生产力的指标,而且与群体产量呈极显著的正相关,能在高水平上实现产量因素的协调增长。粒叶比遗传力高,测定方法简单,是一个较好的有实用价值的选择指标。In order to improve breeding foreseeability and selection efficiency, the conception, genetw characters, and the relationship with yield components and yield of grain-leaf ratio were discussed. We thought that grain-leaf ratio was not only an index to measure the coordination ability of sink,, resource and stream of wheat population and the photosynthetic productivity per unit leaf area, but showed significantly positive correlation with wheat grain yield. The high grain-leaf ratio could realize the yield factors coordinated growth in high level. The grain-leaf ratio had high heritability and easy to measure, so it could be a practical index applied to wheat breeding.
