复合杂交能丰富后代遗传基础,可能选出优点突出或突破性品种,但方向难测,规模和选择难度较大。利用优良基因结合体进行阶梯式杂交的方法(E.G.S.C育种方法)可以把单交和各种复交有机融合在一起,能够极大地缩小育种规模,集中选择目标,减少选择难度,集中多个亲本优良性状,造出遗传基础相当丰富的基因型,从而使选育适应各种需要的突破性品种变得比较容易和有把握。应用模式3,经过20余年研究,已陆续培育出高蛋白高赖氨酸、白皮大粒、商品性好、高产优质及高产大穗、抗倒广适等特性各异的5个系列品种。应用模式1和模式2在积累优良基因上会有更好的效果,但是复杂程度更高。
Complex hybrids can enrich the genetic basis of offspring, may choose to highlight the advantages or breakthrough breeds, but difficult to detect the direction of the scale and the choice of more difficult. The step-by-step hybridization method (EGSC breeding method) using excellent gene combinations can organically combine single cross and multiple crossbreds, greatly reducing the breeding scale, selecting targets centrally, reducing the difficulty of selection, and concentrating the superior traits of multiple parents , Resulting in a genetically rich genotype, making it easier and more secure to breed breeds that meet a variety of needs. Application mode 3, after more than 20 years of research, have successively cultivated five series of varieties with high protein and high lysine, white big grain, good commercial quality, high yield, high quality and large spike, lodging resistance and wide adaptability. Applying patterns 1 and 2 yields better results in accumulating good genes, but with more complexity.
