国内外一致认为小麦、大豆等自交作物的原原种是育种者的种子。但是育种者的种子来源在认识上以及所产生其原原种的方法上却有较大的分歧。为了阐述这个问题,首先从自交作物的育种途径和方法谈起。 Domestic and foreign unanimously agreed that the original seed of self-transcribed crops such as wheat and soybean is the seed of the breeder. However, the breeders’ sources of seeds are quite different in their understanding of the origin of the seeds they produce. In order to elaborate this question, we begin with the breeding ways and methods of self-cross crop.
