为适应贵州生态条件对小麦特早熟与高产的需要,在遗传研究的基础上,同时育成了一些在贵阳为特早熟、特大粒、特大穗的小麦新种质,并育成几个有希望为生产直接利用的特早熟、特大粒丰产新品种。特早熟新种质比早熟对照种早15~20天,特大粒新种千粒重64克,特大穗新种质每穗有29~32个小穗。实践证明,为稀特种质选育提供理论指导的遗传研究,应特别重视对超亲极端型个体的研究分析。特早熟育种的亲本选配,要重视个体生育阶段的互辅性。选育半冬性特早熟,是解决高产与早熟矛盾的有效途径。
In order to meet the need of special precocious and high-yielding wheat in Guizhou, on the basis of genetic research, some new germplasms of wheat with special precocious, extra-large and extra-large spikes were bred and several promising germplasms were produced Direct use of the special precocious, extra-large grain yield new varieties. The special precocious germplasm is 15 to 20 days earlier than the precocious control species, the extra-granular new species has a grain weight of 64 grams, and the extra-large new germplasm has 29 to 32 spikelets per spike. Practice has proved that, for the rare germplasm selection and breeding to provide theoretical guidance for genetic research, special attention should be paid to the study of super-polar extremist individuals. Premature breeding of the parent matching, we must pay attention to the individual childbearing phase of complementary. It is an effective way to solve the contradiction between high yield and precocious puberty.
