世界小麦矮源很少,据了解,一个是我国含有部分显性矮生基因的大姆指矮,另一个是日本具有两个主要隐性半矮基因的农林10号。本世纪中期以来,许多国家利用这些矮源材料已培育出了一批新的矮秆品种和材料,为世界小麦产量大幅度增加作出了新贡献。但由于矮源少,矮生基因单一,遗传基础贫乏,育种界再度重大突破面临困难。所以,寻求新的矮源和对新矮源的利用价值进行研 There are very few dwarf sources in the world. One is that the short-lived dwarf gene that contains some dominant dwarf genes in our country is short, and the other is Agriculture and Forestry 10 in Japan, which has two major recessive semi-short genes. Since the middle of this century, many countries have used these dwarf source materials to cultivate a new batch of dwarf varieties and materials, making a new contribution to a substantial increase in world wheat output. However, due to short dwarf source, single dwarf gene and poor genetic basis, major breakthroughs in the breeding community face difficulties. Therefore, the search for new dwarf sources and the utilization of new dwarf resources research
