Compared with different type male-sterile line found at binucleate microspore stage non-1B/ 1R type male sterile lines and YS type male sterile lines both increase l7kD polypeptide compared with maintainers.

同时通过对比不同类型的不育系发现非1B/1R类K型不育系732A和YS光温敏不育小麦A3017在小穗发育的二核期均多1条分子量大小为17kD的多肽。

The sterile and fertile plants of BC3 generation, derived from the hybridization between sterile line and restorer line and maintaining line, were detected by GISH-dcFISH. The observations showed that the fertile plants were all the Brassica napus-Xinjiang wild Sinapis arvensis monosomic alien addition lines, and the sterile plants had no Sinapis arvensis chromosome.

不育系分别与保持系、恢复系Nsa恢1、保持系杂交后获得了BC3代不育株及可育株，GISH-dcFISH分析结果表明，BC3代可育株为甘蓝型油菜－新疆野生油菜单体异附加系，而不育株中不含新疆野生油菜染色体。

The results showed that except pods of main inflorescence, the other characters of the sterile and normal cytoplasms had not significant difference by t test. The correlation coefficients of length of main inflorescence, No. of first time branches and glucosinolates between sterile and normal cytoplasms was at 5 percent significant level, but correlation coefficients of the others was not significant. There were positive effects of male sterile cytoplasm on glucosinolates and weight of 1000 seeds, but different effects on the other characters when combinations were different.

结果表明：考察的12个主要性状中，除主序角果数不育胞质杂种F1和可育胞质杂种F1检验差异达5%显著水平外，其余11个性状2种胞质杂种F1上标 t检验差异不显著；主序有效长、第一次分枝数、硫苷等3个性状的可育胞质与不育胞质间线性相关关系显著，其余9个性状的线性相关关系不显著；NEA不育胞质对多数组合的硫苷和千粒重有优良相对效应，对其余性状的相对效应则组合不同正负效应不同。

With the aid of an assistant, the foot is inserted into a pillowcase, and the edges of the case are held together with a towel clip. To make a compact mass of these rather voluminous drapes, a sterile bandage is wrapped snugly from the toes proximally to the proximal edge of the towel and pillowcase. Alternatively, a sterile stockinette rolled from the toes to the groin can be used. The area over the knee is cut away as described in the section on draping the edges of the incision. The stockinette is then covered with a sterile bandage to just below the knee.

在助手帮助下将足插入枕套，枕套边缘由巾钳固定在一起，为使其紧凑，可用消毒绷带从足趾缠绕至治疗巾和枕套的近端边缘，也可改用消毒的弹力织物从足趾套至腹股沟，膝关节表面的织物应于切除，如同切口周围铺单中介绍的方法，这种弹力织物在膝关节以下的部分用无菌绷带缠绕固定，其余铺单方法与足部铺单相同。
