玉米植株色泽的遗传是比较复杂的,但是玉米植株的日光红性状对绿色是显性,在日光照射下,这一性状的显著差异就会表现出来。正因为这一性状的表现比较稳定,人们常用它来作为衡量玉米自交系繁殖田鉴别纯度的指标。出苗后,到自交系繁殖田调查非种植自交系芽鞘色的植株率,由此可估算该自交系的混杂程度。如特征是红芽鞘的自交系隔离区,出现绿芽鞘株率为2.25%,而另一特征是绿芽鞘的自交系隔离
The inheritance of maize plant color is more complicated, but the red sun trait of maize plant is dominant to the green, and under the sunlight, the significant difference of this trait will be revealed. Precisely because of the relatively stable performance of this trait, it is often used as an indicator of purity in maize inbred lines. After emergence, inbred lines of inbred fields were surveyed non-planting inbred line bud sheath color plant rate, which can be estimated in the hybrid of inbreds. For example, in the inbred isolate of the red bud sheath, the rate of green shoot sheath is 2.25%, while the other feature is the green shoot sheath inbred isolate
