    • 摘要: 利用太谷核不育基因设计了一个小麦轮回选择育种程序,即以含太谷核不育基因的辐繁17与其它8个赤霉病抗笥来源不同的小麦品种(系)分别杂交,再互交,组成基础群体,进而选择流通 株和可育株并杂交开展轮回选择和抗赤霉病小麦新品种的选育,从第一轮回选择群体中选出一批赤霉病抗性强的单株,经系统育种程序选择和鉴定,育成了抗赤霉病小麦新品种华南T2003和华南T531,对用轮回选择和系统育种结合的方法进行了小麦抗赤

       

      Abstract: A recurrent selection breeding procedure was designed by means of laigu genic(Tal) male sterile gene and employed to develop new wheat varieties with resistance to scab. Fu-Fan No. 17 with the gene Tal and other eight wheat varieties(lines) with resistance to scab were used to construct the base population of recurrent selection, New scab-resistant varieties Huanan T2003 and T531 were developed from the plants that were selected after one cycle of selection by pure line breeding method. The experience of developing new wheat variety with resistance to scab using recurrent selection method was briefly summarized.
