摘要
通过田间自然鉴定 ,研究了 9个欧亚种葡萄品种及其 1 0个杂交组合 4 1 2株杂种对黑痘病的抗性及其遗传。结果表明 ,不同组合后代群体的抗性呈连续性分布 ,表现出多基因控制的数量性状遗传特征。欧亚种葡萄品种中存在黑痘病的微效抗性基因 ,品种间杂交后代出现了一定比例的抗性单株。
The Inheritance of Resistance to anthracnose ( Spheceloma ampelinum de Bary ) in 412 hybrids of 9 cultivars of Vitis Vinifera L. was studied by natural infection in field conditions.The results showed that the disease resistance of F 1 hybrids was continual and had quantitative character inheritance that was controlled by multiple gene.There was minor gene of the disease resistance in the Vitis Vinifera L. And there were some disease resistance plants in F 1 generation.Effects of the disease resistance gene were additive.
