在小麦的抗病育种工作中,往往花费了六、七年时间,选育出的一个抗病丰产品种,推广几年以后,抗病性已经丧失。因此,人们就在探索如何克服抗性丧失的途径。有人提出“一般抗病性”和“水平抗病性”等概念。许多工作者建议把这些概念应用于植物的抗病育种工作中。无论是所谓“一般抗病性”还是“水平抗病性”、“田间抗性”、“慢锈性”等,在麦株群体中是比较容易表现出来的。然而育种工作,是从单株
Disease resistance in wheat breeding efforts, often spent six or seven years, bred a variety of disease-resistant varieties, a few years after the promotion, disease resistance has been lost. Therefore, people are exploring ways to overcome the resistance loss. Someone put forward such concepts as “general disease resistance” and “horizontal disease resistance”. Many workers recommend applying these concepts to plant disease-resistant breeding. Whether it is so-called “general disease resistance” or “horizontal disease resistance”, “field resistance”, “slow rustiness” and the like, it is relatively easy to manifest in the wheat plant population. However breeding work is from a single plant
