摘要
利用配对设计方法,田间自然鉴定及室内离体叶圆片接种鉴定,系统地研究了8个欧亚种葡萄品种(系)及1个欧山杂种对葡萄霜霉病及黑痘病的抗性,同时对其中的7个欧亚种葡萄品种对两病的抗性关系进行了研究.结果表明,供试品种(系)对霜霉病与黑痘病的抗性存在负相关,但相关性不显著,由此可以推断,控制两病的微效多基因不是同一基因组或它们是连锁强度不大的2个基因组,即抗霜霉病的品种不太抗黑痘病,抗黑痘病的品种不太抗霜霉病,同一品种对两病的抗性表现交错现象.
Using the method of matching design, the resistance to Plasmopara viticola and Sphaceloma ampelinum, as well as resistance relationship were studied with 8 varieties (strain) of Vitis vinifera and a hybrid of V. vinefera and V. amurensis by natural infection investigation in field and artificial inoculation evaluation on leaf disc in lab. The results showed that the distribution of the resistance to P. viticola was negative correlated with that of the resistance to S. ampelinum, but not significantly. So it could be inferrred that slightly effect multiple-genes which controlled P. viticola and S. ampelinum were not same gene-group, or were two gene-groups whose degree of chain were not strong. But the two diseases had some extent negative relationship indeed. That is to say, varieties having strong resistance to P. viticola had not same degree resistance to S. ampelinum, conversely, it was the same. The resistance of same variety to two disease emerged interlocking phenomena.
