从根本上说,育种目标是指不同生产发展时期对品种所要求解决的问题。根据这个涵义,育种目标就是随生产的发展相应地提出对新品种的要求。例如,在六十年代初,山西中部麦区锈病发生频率较高、较重,使当时生产上的主干品种农大183严重感病。这说明不解决品种的锈病问题,当时小麦生产就难以发展。紧接着随着小麦生产条件好转,科学种田水平提高,产量逐步发展,一些品种抗倒能力较
Fundamentally speaking, the goal of breeding refers to the different production and development of the species required to solve the problem. According to this conception, the goal of breeding is to put forward the requirements of new varieties correspondingly with the development of production. In the early 1960s, for example, the incidence of rust in the wheat fields in central Shanxi was higher and heavier, making the main variety of agricultural production at the time, 183, seriously ill. This shows that do not solve the problem of species of rust, wheat production was difficult to develop at that time. Followed by the improvement of wheat production conditions, raising the level of scientific farming, the gradual development of production, some varieties of anti-collapse ability
