利用杂种优势大幅度提高农作物产量,国内外研究和实践证明,小麦杂种优势也很明显,一般杂交种可比常规品种增产15%～30%,我国小麦杂种优势利用研究经过30多年探索研究,目前在化杀杂种、“三系”杂种及光温敏核不育杂种小麦选育方面已有了较大的进展,特别是化杀制种技术的新突破为杂种小麦在“九五”期间逐步走向生产应用展示了广阔的前景。普遍认为,化杀体系操作简单、去雄彻底、便于亲本组配、选
Heterosis advantage of greatly increase the yield of crops, domestic and foreign research and practice proved that wheat heterosis is also obvious, general hybrids yield 15% ~ 30% more than conventional varieties, wheat heterosis utilization research in China after 30 years of exploration and research, at present in There has been a great progress in the breeding of hybrids, “three lines” hybrids and the thermo-sensitive genic male sterile hybrid wheat. In particular, "During the gradual application of production and application of the broad prospects. It is generally believed that the killing system is simple and easy to remove, which makes it easy for parents to mix and choose
