A Study of Selection and Utilization of the Synthetic Variety of Foxtail Millet

Kong Yuzhen Cui Wensheng Zhao Zhihai Du Gui Su Yuyuan(Baxia Agricultural Research Institute of Zhangjiakou Prefecture, Zhang jiakou, 075131)  
The test cross was made by use of various types of recessive genie male-sterile materials and different varieties of foxtail millet. The seeds from the sterile spikelets. which was born through mixed open-pollination in F2, were mixed for sowing and pollenizing. Then the exogamy sterile spikelets were selected in the following successive generations for divorsing (the score of thier fertility and sterility was 1:1) , and mixed open-pollination was made among them to change and recombine the genes fully and set a synthetic and dynamic gene pool, from which a suitable and excellent variety-syntheticvariety of millet-was selected. The resuh showed that the synthetic variety-had stronger adaptability and resistibility to diseases, drought and lodging than the varieties obtained through pedigree selection or conventional crossing.
