远缘杂交是创造新物种新类型的一个重要手段。小黑麦就是由小麦和黑麦人工合成的新作物。这种兼有小麦与黑麦遗传特性的双二倍体(包括六倍体和八倍体),具有穗大、粒多、粒重、抗锈、耐渍、抗逆性强和营养品质好等优点,不仅是生产上有推广前途的新作物,同时也是改良小麦品种的好材料。1965年苏联А.Ф.舒雷金教授指出:这种双倍体对于育种具有重要意义。我们试图采用小黑麦与小麦杂交,培育出早熟、大穗、丰产性强、抗病的小麦新品种,把早熟
Distant hybridization is an important tool for creating new types of new species. Triticale is the new crop artificially synthesized from wheat and rye. This double diploid (including hexaploid and octaploid) inheritance of both wheat and rye has the characteristics of large spike, large grain size, grain weight, rust resistance, stain resistance, strong resistance and good nutritional quality Etc., is not only a new crop with promotion prospects in production, but also a good material for improving wheat varieties. 1965 Soviet Union А.Ф. Professor Shu Lei Jin pointed out: This diploid is of great significance for breeding. We tried to use the cross between Triticum and wheat to breed a new variety of early-maturing, big-spike, high yield and disease-resistant wheat.
