生态远缘杂交在小麦育种中起着重要的作用。在亲本材料中具有育种目标所要求的优良性状并且其遗传传递力强的前提下,应用这一亲本选配原则,国内外育成许多适应性广、产量高的优良品种。近年来,我国更多的育种单位用冬小麦与春小麦杂交选育冬小麦或者春小麦品种,取得了一定的成绩,在实践中也提出一些有关冬、春性小麦间杂交性状遗传的问题。 Eco-distant hybridization plays an important role in wheat breeding. Under the premise that the parent material has excellent traits required by breeding objectives and its genetic transmission ability is strong, a number of excellent varieties with high adaptability and high yield have been bred domestically and internationally under the principle of matching parents. In recent years, more breeders in our country have used winter wheat and spring wheat to breed winter wheat or spring wheat. Some achievements have been made. Some problems about the inheritance of the hybrid traits in winter and spring wheat have also been put forward in practice.
