利用雄性不育培育杂种小麦是近年来国内外小麦育种新动向,据报导,利用雄性不育制成的杂种小麦,一般可增产30%左右,甚至更多。这对大幅度地提高小麦单位面积产量,实现粮食上《纲要》,将会起到促进作用。我所在省农业局、科教局领导下,在各省市兄弟单位大力支持下,于一九七一年秋开展此项研究工作。为了加快步伐,适应生产发展的大好形势,我们利用我省优越的自然条件,进行南部冬播、中部春、夏播一年种植三次,采取回交转育、杂交选择、测交鉴定等方法,初步获得了转育三代以上的田 It is reported that the hybrid wheat made by using male sterility generally increases the yield by about 30% or even more. This will greatly enhance the yield per unit area of ​​wheat and realize the “outline” of grain, which will play a catalytic role. Under the leadership of the Bureau of Agriculture and Science and Education Bureau of our province, this research work was carried out in the autumn of l971 with the vigorous support of the fraternal units of various provinces and cities. In order to speed up the pace and adapt to the good situation of production and development, we use the superior natural conditions of our province to plant winter mulch in the south and spring and summer sowing in central China three times in a year. The methods of backcrossing, crossing selection, Preliminary access to the transfer of more than three generations of the field
