对4种杂交模式62个组合杂交后代抗寒力及果实经济性状的遗传进行了研究。统计结果表明:在露地越冬条件下,4种杂交模式后代抗寒力依次为:(AA×BB)×(AA×BB)>(AA×BB)×AA>(AA×BB)>(AA×BB)×BB。在果稳重量、果粒重量、果实含糖量、含酸量等经济性状遗传上,4种杂交模式后代倾向山葡萄,耶德小、粒小、糖低、酸高。从选育酿造品种看:AA×BB后代为中间型;(AA×BB)×AA后代抗寒性好,可酿红葡萄酒;(AA×BB)×(AA×BB)和(AA×BB)×BB后代可选出酿造白葡萄酒品种。
The inheritance of cold resistance and economic traits of 62 combinations of 4 cross hybrids were studied. The statistical results showed that the cold resistance of the four hybridization progenies was (AA × BB) × (AA × BB)> (AA × BB) × AA> (AA × BB)> (AA × BB) × BB. In the genetic stability of fruit weight, fruit weight, fruit sugar content, acid content and other economic traits, the four hybrid progenies tend to grape, small, small size, low sugar, high acid. From the selection of brewing varieties: AA × BB offspring is intermediate; (AA × BB) × AA descendants have good cold resistance and can brew red wine; (AA × BB) × (AA × BB) and (AA × BB) × BB offspring can choose to brew white wine varieties.
