摘要
瑞青8号是以青花菜细胞质雄性不育材料CMS034为不育源,与优良稳定的青花菜自交系0512经过多代回交转育,育成的不育性稳定、经济性状良好的青花菜细胞质雄性不育系CMS0512,再以雄性不育系CMS0512为母本,优良的青花菜自交系038为父本配制的杂交一代品种。瑞青8号株高60 cm左右,株幅65 cm左右,叶色绿,叶面光滑;花球半球形,横径17.5 cm左右,纵径14 cm左右;花球紧密,蕾粒细小,色浓绿,花茎细,不中空,单花球重0.55 kg左右,产量达1400 kg/667 m2左右。属中早熟,定植后72 d左右采收,腋芽2～4个,在主花球采收后,侧花球可连续采收1～2次,植株生长势强、整齐度高、抗逆性强,抗霜霉病、黑腐病。
Cauliflower male sterile line CMS034 used as sterile source was crossed and backcrossed by broccoli inbred line 0512 with excellent stability for several successive generations, and broccoli cytoplasmic male sterile line CMS0512 with stable ste- rility and good economic traits was bred. Then, CMS0512 （female parent） was hybridized by good broccoli inbred line 038 （male parent）, finally the broccoli hybrid Ruiqing No. 8 was bred. The plant height of Ruiqing No. 8 is about 60 em, and its plant breadth is about 65 cm with green and glossy leaves. The ball - flower is semi - circular and close with the horizontal diameter of a- bout 17.5 cm and vertical diameter of about 14 cm, and it has small bud granulocyte, dark green color, and fine flower stems with- out hollow. Its single ball - flower is about 0.55 kg in weight, and its yield is about 1400 kg/667 m2. Ruiqing No. 8 belongs to middle - early maturing variety, and it can be harvested about 72 d after transplanting. This variety has 2 - 4 axillary buds. After the harvest of main ball - flower, the lateral ball - flowers can be picked continuously for 1 - 2 times. Ruiqing No. 8 has strong growth potential, high uniformity, strong adversity resistance, and resistance to downy mildew and black rot.
