对“八五”以来辽宁省审定的 7个谷子新品种的亲缘关系分析表明 ,目前推广的谷子新品种多数是铁谷1号衍生系 ,这些新品种与铁谷 1号相比均有所改进 ,但产量没有大的突破 ,抗逆性还存在一定的问题 ,因此必须重视种质资源的研究 ,拓宽谷子遗传基础。传统的育种方法与生物技术、遗传工程等先进手段相结合 ,将使谷子育种再上一个新台阶 The genetic relationship analysis of seven new millet varieties approved by Liaoning Province since the Eighth Five-Year Plan shows that the majority of the new millet varieties promoted at present are the derivative strains of TGP No.1, and these new varieties have all improved compared with that of Tiangu 1 However, there is no major breakthrough in yield and there are still some problems in resistance. Therefore, we must pay more attention to the research of germplasm resources and broaden the genetic basis of millet. The combination of traditional breeding methods with advanced technologies such as biotechnology and genetic engineering will bring millet breeding to a new stage
