近几年来,沈阳地区辣椒毒病异常严重,使产量、质量受到很大影响。本项研究是为了搞清毒源种类,以便为制定综合防治措施以及选择具有特异抗病基因材料,为抗病育种提供亲本。我们于1979～1980年,在调查全省辣椒毒病发生规律的同时,对沈阳地区的辣椒毒病的毒源种类进行初步鉴定。一、材料和方法(一)毒源采集及症状类型。从沈阳市郊区六个蔬菜生产大队(双喜、南塔、长白、长青、马官桥、石庙)采取自然发病株。方法是:先套袋后隔袋折枝,放入冰壶内保存带回。二年来,于发病初期,高峰期及末期共采集毒株129份。毒株的症状类型有:
In recent years, Shenyang, an exceptionally severe pepper disease, so that the yield, quality has been greatly affected. The purpose of this study is to find out the types of poison sources, in order to provide comprehensive prevention and control measures and select specific disease-resistant gene materials to provide parents for disease-resistant breeding. From 1979 to 1980, while investigating the law of the occurrence of pepper poisoning in the province, we initially identified the types of the poisonous source of pepper poisoning in Shenyang. First, materials and methods (A) drug collection and type of symptoms. From the outskirts of Shenyang City, six vegetable production brigade (Double Happiness, the South Tower, Changbai, Evergreen, Ma Guanqiao, Stone Temple) to take a natural strain. The method is: After bagging bags bag broken branches, into the curling save back. In the past two years, 129 strains were collected at the initial, peak and end of the disease. Symptom types of strains are:
