向日葵的“三系”选育和其他作物的“三系”选育工作一样,存在着很大的盲目性,只有在大量的杂交和测交工作的基础上,才有可能使“三系”配套。在“三系”的保存、繁殖和制种工作中,还会遇到“三系”错乱的现象。为了试图解决上述问题。我们利用了同工酶电泳技术,分析向日葵不育系、保持系和恢复系酶谱情况,探讨利用此技术作为向日葵“三系”选育手段之一和区分“三系”的可能性。
Like the “three lines” of other crops, the “three lines” of sunflower breeding have great blindness. Only on the basis of a large number of hybridization and diplomatic work, will it be possible to make “three lines” Supporting. In the “three lines” of preservation, breeding and seed production, they will also encounter the “three lines” disorder. In an attempt to solve the above problem. We used the isoenzyme electrophoresis technique to analyze the situation of the sunflower sterile, maintainer and restorer zymogram, and discussed the possibility of using this technology as one of the “three lines” breeding methods for sunflower and distinguishing the “three lines”.
