(3)抗病检定法抗病已成为对所有作物最重要的育种目标之一。最近在水稻稻瘟病激发年,感病性品种几乎绝产,而栽培抗病性品种时则能控制到减产百分之二十五之例。同时,在施农药上,很多情况下一年内有的施十多次。考虑这种现实情况,深感育成抗病性品种的重要性。1)病的种类和验定法近代育种,基本上通过杂交和突变诱
(3) Disease Resistance Testing Disease resistance has become one of the most important breeding objectives for all crops. Recently, in the year of rice blast provocation, the susceptible varieties were almost absolutely dead, while the cultivars that cultivated the disease-resistant varieties were able to control the yield reduction by 25%. At the same time, pesticides applied in many cases within a year Shi Shi Shi many times. Considering this reality, we are deeply impressed by the importance of developing disease-resistant varieties. 1) the type of disease and verification method of modern breeding, basically through hybridization and mutation induced
