近年来,随着生产水平和育种水平的不断提高,我省各种短日照作物育种都面临着一个基因库日趋狭窄问题,如玉米的高产、抗病和大豆高蛋白基因源等等。为解决这一问题,我省广大短日照作物育种工作者已相继从国内外及野生资源中引入了大量新种质,如大豆引入了我国南方栽培大豆和野生大豆中的高蛋白基因源,玉米、谷子引入了低伟度 In recent years, with the continuous improvement of production level and breeding level, all kinds of short-day crop breeding in our province are faced with the problem of a narrower gene bank, such as high yield of corn, disease-resistant and soybean high-protein gene source and so on. In order to solve this problem, a large number of short-day crop breeders in our province have successively introduced a large number of new germplasms from domestic and foreign wild resources. For example, soybean introduces high-protein gene sources from cultivated soybean and wild soybean in southern China, and corn , Millet introduced a low degree
