米丘林在实践工作中告诉我们:嫁接能使一个有机体接受另一个有机体的营养,使新陈代谢的型式改变,影响其遗传性,可能产生无性杂种。一般现有的新品种小麦的传遗性都很容易动摇,由品种间杂交所获得的杂种,既具有杂种优势,而且又不易分离。利用生态上相差大的类型进行杂交,在后代方面就可能有很大的分离现象,并且具有特别强的可塑性,因而更容易定向地培育杂种,培育出理想的新品种。这个试验是以徐州438小麦为接穗,白玉皮小麦为砧木作嫁接的,通过替换胚乳,理想能进一步提高徐州438小麦的产量。因为:徐州438小麦的优点是分蘖力强、越冬性强、早熟、产量高而稳定。特征为有芒、白穗、白籽、硬粒、千粒重27克、籽粒品质与面粉品质均好。但
In practice, Michurin tells us that grafting allows one organism to receive nutrition from another organism, change its metabolic patterns, affect its heredity, and possibly produce clonal hybrids. Generally, the inheritance of the existing new varieties of wheat is easily shaken. The hybrids obtained from the cross between varieties have both heterosis and are not easily separated. The use of ecologically different types of crosses can have a great deal of segregation in the offspring and have a particularly strong plasticity that makes it easier to grow hybrids in a targeted manner and to develop desirable new varieties. This experiment is based on Xuzhou 438 wheat as the scion, white jade wheat as the rootstock for grafting, by replacing the endosperm, the ideal can further improve Xuzhou 438 wheat yield. Because: Xuzhou 438 wheat has the advantage of strong tillering ability, strong winter, early maturity, high yield and stability. Characteristics are Mans, white spike, white seeds, hard particles, grain weight 27 grams, grain quality and flour quality are good. but
