浅论小麦增小穗育种的新进展

Argurmentation of New Progresses of Increasing Spikelets in the Wheat Breeding

本文指出小麦较多小穗种质利用中存在的严重问题,提出创造新的较多小穗和多小穗种质的新方法及其步骤。进而论述了应用这种新方法创造具有较高应用价值的较多小穗和多小穗新种质并解决晚熟问题取得的最新进展。最后分析了增小穗育种新方法创造新种质的特点,认为该方法的创新在于为小麦超高产育种开辟新的途径,并将推动小麦高光效育种进入新的阶段。

The paper, first, indicates a severe problem in use of spikelets genotypes, and Presents a new method and its steps to create new more spikelets and many spikelets genotypes. Second,the paper argurmentates new progresses of using the new method for creating more spikelets and many spikelets genotypes with a high breeding practical valve, and solving the question late to ripen about it. Third, the paper analyses the charactoristics to create new genotypes and points out the new method would be a new way for developing more high yield varieties in wheat, and would promote high photosynthetic rate breeding into a new stage.
