【摘要】 通过田间自然鉴定、室内离体接种鉴定和田间接种鉴定，研究了原产我国的葡萄属野生种与欧洲葡萄种间杂交７ 个组合的亲本和后代对炭疽病的抗性及其遗传。结果表明，后代组合群体的抗病性呈连续性分布，表现出数量性状遗传的特征。野生种中主要存在主效抗性基因，其遗传效应占优势，欧洲品种中存在微效抗性基因，子代的抗病性是这两类基因共同作用的结果。更多还原

【Abstract】 Resistance to grape rot [ Glomerella cingulata (Ston.) spauld et schrenk] of both the parents and hybrids of 7 interspecific cross combinations is studied through field natural evaluation,labaratory isolated inoculation and field inoculation evaluation.The results are as follows:the hybrids display the characteristic of the quantitative inheritance with the traits of continuous distribution.The major resistant genes exist in the wild species which reveal the dominant effect.While the minor resistant genes exist in Vitis vinifere parents.The resistance of hybrids to the disease is controlled by both of them.更多还原
