葡萄杂交育种是一项周期性较长的工作。由于杂种实生苗的童期较长,由播种至第一次开花结果一般需要3—5年时间,所以育成一个新品种往往需要10—15年的时间。而且葡萄和其它无性繁殖的木本果树一样,遗传上杂合程度高杂种后代分离幅度大,所需性状出现的频率较低,给育种工作带来很大的困难,需要花费较长时间和较大的人力、物力和财力。杂交育种成败的关键在于根据性状遗传规律科学的选配亲本,而目前国内外均是在杂交育种中附带总结性状遗传规律,没有系统进行性状遗传研究工作,这样也给杂交育种中亲本选配带来一定的盲目性。本研究在国内首次科学地设计若干组合,专门进行葡萄性状遗传研究,期望能总结出葡萄性状遗传特点和规律,丰富葡萄性状遗传理论,为更有效地开展葡萄杂交育种及合理选配亲本提供理论依据。
Grape hybridization breeding is a longer period of work. Since hybrid seedlings have a longer childhood, it takes about 3-5 years from sowing to first flowering, so breeding a new variety often takes 10-15 years. And grapes and other asexual woody fruit trees, the genetic heterozygosity of a high degree of segregation of hybrid progeny, the required frequency of occurrence of the lower characters, breeding work has brought great difficulties, it takes a longer time and more Large manpower, material and financial resources. The key to the success or failure of crossbred breeding lies in the scientific matching of parents according to the genetic laws of traits. At present, the inheritance laws of traits in hybrid breeding are attached both at home and abroad, and the genetic research of traits is not systematically carried out. Thus, To a certain degree of blindness. In this study, we first scientifically designed several combinations in China for the first time to study the inheritance of grape traits. We hope to summarize the genetic traits and laws of grape traits, enrich the genetic theory of grape traits, provide theory for more effective hybridization breeding and rational selection of parents in accordance with.
