小麦有性远缘杂交是创造新物种,选育新品种或新类型的重要途径与方法。国内外研究表明,小麦与天兰冰草通过一次有性属间杂交,一次自交或回交,多次个体选择的方法是选育新品种行之有效的成功经验。我所自1957年开展小麦——天兰冰草有性远缘杂交的研究以来,先后曾配制百余个杂交组合,选育出“小冰1号”、“龙麦1号”、“龙麦2号”等良种,用于生产。为了减少野生天兰冰草等不良性状对其杂种后代的影响,更有目的地把天兰冰草的
Wheat sexual sexual hybridization is to create new species, breeding new varieties or new types of important ways and methods. Domestic and foreign studies have shown that wheat and Celastrus glaucum through a sexual intercross, a self-self or backcross, multiple individual selection method is successful breeding new breed of successful experience. Since 1957, when we carried out the research on the sexual crossbreeding of wheat-tannin, we have formulated more than 100 hybrid combinations to produce “Xiaobing 1”, “Longmai 1” and “Dragon Wheat 2 ”and other seeds for production. In order to reduce the adverse effects of the tragacanth and other undesirable traits on their hybrid offspring,
