采用数量遗传方法，选用两个保绿性强的玉米自交系(齐319、178)和两个保绿性差的自交系(Mo17、BM)组配4套F1、F2和回交群体，研究保绿性的遗传规律，分析保绿性的基因效应。4套组合6个世代的保绿鉴定结果表明，玉米叶片保绿基因的加性、显性和互作效应普遍存在。玉米保绿性状广义遗传力变化范围为59.93%～76.82%，加性方差占遗传方差的比值变化范围为40.70%～60.10%。以齐319为保绿亲本的组合至少存在两对保绿基因，而以178为保绿亲本的组合至少由一对基因控制。

The inheritance of stay-green was studied in progenies derived from four crosses between two stay-green lines, Q319 and 178, and two non-stay-green lines, Mo17 and BM. The results showed that additive and dominant gene effect as well as gene interactions could be found in the inheritance of stay-green. The broad heritabil-ity for stay-green ranged from 59.93%to 76.82%and the ratio of narrow heritability to genetic heritability ranged from 40.70%to 60.10%. Q319 and 178 were estimated to contain at least two and one stay-green genes, respectively.
