从大量的杂种后代材料中,可以看到冬小麦叶色变异是丰富的。正确认识这些性状将有助于在育种工作中进行正确的选择。1978—1980年我们对冬小麦品种的叶片颜色做了观察研究。试验材料是本校冬小麦育种试验地原始材料圃中原始材料及 F_3——F_6代家系材料,采用 x~2法检验叶色与性状的相互关系。分析结果,冬小麦叶片颜色与品种抗逆性、适应性有密切关系,是选种育种的一个有实践意义的重要指标。据对我校原始材料圃原始材料的观察,我国长江流域、黄河流
From a large number of hybrid progeny materials, we can see that winter wheat leaf color variation is rich. Correct understanding of these traits will help to make the right choice in breeding work. From 1978 to 1980 we observed the leaf color of winter wheat varieties. The experimental materials were the original materials and F_3 - F_6 generation family materials in the original wheat nursery and breeding field in our university. The correlations between leaf color and traits were tested by x ~ 2 method. As a result, the color of winter wheat leaves is closely related to the resistance and adaptability of varieties, which is an important and practical indicator of breeding. According to the original material of our school nursery stock observations, the Yangtze River in China, the Yellow River
