农作物抗病育种的实践表明,大多数品种在其抗性特征方面均显示出免疫方面的异质性,往往这种异质性与构成群体植株的不同遗传特性有关。而那些具有多抗性的类型,其实用价值最大(1978;1972;1972)。鉴此,根据抗性特征研究品种的生物系群组成及其鉴定方法有着重要的意义。植物抗病性的现有鉴定方法可以分成两类:一类是通过注射、切口、机械损伤等途径把侵染源直接引入植物组织内;另一类则是通过向植物喷射孢子悬浮液、撒孢子粉以及把病菌移植到土内等途径,使病
The practice of disease-resistant breeding in crops has shown that most varieties show an immunological heterogeneity in their resistance traits, often associated with the different genetic traits of the plants that make up the population. And those with multiple resistance types, the most valuable (1978; 1972; 1972). In view of this, it is of great significance to study the composition of the biota and its identification methods based on resistance traits. Existing methods for identifying plant disease resistance can be divided into two categories: one is to directly introduce the infection source into the plant tissue by means of injection, incision, mechanical damage, and the like; the other is to spray the spore suspension onto the plant, Spore powder and the bacteria transplanted to the soil and other means to make the disease
