S型细胞质雄性不育系的一对近等基因系S-Mo17Rf3Rf3 和S-Mo17rf3rf3为材料，采用TdT介导的dUTP DNA末端标记、细胞色素C免疫原位杂交和DNA寡聚核小体片段电泳等方法，分别在细胞学水平和DNA水平上研究了玉米CMS-S小孢子败育的细胞程序性死亡过程。

In order to determine the genetic differences between high molecular weigh glutenin subunits 17+18 and 7+8, HMW-GS 17+18 was introduced into Longmai 20 by 6 consecutive backcrosses with biochemical marker assisted selection. The near isogenic lines of HMW-GS 17+18 and 7+8 were obtained and grown in the experimental field of Crop Breeding Institute of Heilongjiang Academy of Agricultural Sciences in 2006. The field experiments were designed using the method of two line-contrast arrangement with four replicates.

为了解小麦Glu-B1位点HMW-GS 17+18与7+8的遗传差异，利用生化标记和连续6次选择性回交的方法将17+18亚基转移到黑龙江省小麦品种龙麦20中，获得了龙麦20的Glu-B1位点HMW-GS17+18与7+8的近等基因系。2006年将NILs种植在黑龙江省农业科学院育种研究所的试验田，田间设计采用双列对比排列，4次重复。

A cross was made between Zhenshan 97 and Zhenshan 97, a near isogenic line that derived its Wx allele from Minghui 63 by sucessive backcrossing.
