细胞质雄性不育（CMS）是利用杂种优势的重要育种途径之一，利用20个不同来源的向日葵自交系进行了育性鉴定，结果表明，“NEWFREE”细胞质雄性不育系具有不同于PET1的特性，很可能是一种新的细胞质。迄今为止，“NEWFREE”细胞质雄性不育系的育性鉴定结果表明，“NEWFREE”细胞质雄性不育系是一种新的细胞质雄性不育系。“NEWFREE”具有多个保持系，但无恢复系，不育性稳定，是生产无花粉观赏向日葵杂交种的潜在资源。
Cytoplasmic male sterility(CMS),one of the most important breeding ways to utilize hybrid preference,is used in producing hybrid in sunflower in the world.That is why to find and application male sterility and restoration lines are focus of research.Twenty inbred lines from different origins were used in testing fertility in this study.It showed that "NEWFREE" CMS characterizes different from PET1 and very possibly is a new cytoplasm.So far "NEWFREE" has more than one maintainer lines but restoration lines are not available.Its sterility shows stable and is a potential recourse to produce pollen-free ornamental sunflower hybrid.
