野生毛葡萄及其远缘杂交后代栽培性状调查和评价

Investigation & Evaluation on Culture Character of Wild Species of V. quinquangularis Rehd and Hybrids of V. vinifera-V.quinquangularis

采用田间调查和室内分析相结合的方法,对7个不同野生毛葡萄株系及5个选育的毛葡萄远缘杂交后代196、296、B2、741、213的栽培性状以及果实品质进行调查分析研究。结果表明,5个毛葡萄远缘杂交后代的物候期均要早于野生株系,杂交后代的果实品质优于野生株系;对黑痘病的抗性方面,野生毛葡萄表现为免疫,远缘杂交后代遗传了毛葡萄对黑痘病的高抗病性,表现为高抗和抗病。

The present survey was carried out to determine the culture character and berry quality by applying field investigation coupled with lab analysis to assay 7 various wild species of V.quinquangularis Rehd and five hybrids of V.vinifera V.quinquangularis： 196,296,B2,741,213.The results showed that among the tested varieties,main phenological phases of hybrids were earlier than the wild species of V.quinquangularis Rehd,furthermore the berry quality of hybrids was superior to that of the species of V.quinquangularis Rehd.In terms of the Anthracnose disease resistance,the hybrids of V.quinquangularis Rehd V.vinifera was highly resistible to it,while the wild species of V.quinquangularis Rehd was immune to it.
