摘    要:从日本引进青花菜杂种19份,通过秋季田间经济性状和翌年春季开花习性鉴定,筛选出7份青花菜不育材料.用甘蓝类蔬菜自交系分别与其杂交,后代鉴定结果表明该7份青花菜不育材料为优良的胞质雄性不育材料.2000年以青花菜胞质不育材料为不育源,用甘蓝高代自交系为轮回亲本进行转育,连续回交5代,育成6个综合性状优良、配合力强、雄性不育株率和不育度均达100%的甘蓝胞质雄性不育系及相应的保持系.不育系植株生长健壮,苗期低温无叶片黄化现象,花瓣完全开放,雌蕊发育较正常,蜜腺较发达,雄蕊完全退化,杂交结实正常.利用该不育系配制一代杂种,经田间试验鉴定,筛选出5个优良杂交组合,通过进一步试验、示范,育成甘蓝新品种夏华2号在生产上推广应用.

关 键 词:甘蓝  青花菜  胞质雄性不育系  转育  杂种

Abstract:Through field investigation,seven broccoli cytoplasmic male sterile materials were selected out of 19 crossbreed materials of Japanese broccoli.Six cabbage cytoplasmic male sterile lines were obtained by crossing the male sterile materials with cabbage inbred lines as recurrent parents;the sterile lines showed excellent general characteristics with high combining ability,both of sterile plant rates and sterility reached 100%.Five excellent hybridized combinations were obtained by crossing with the male sterile lines.Xiahua No.2 is a variety that developed through the field screening.
Keywords:cabbage  broccoli  cytoplasmic male sterile line  breeding  hybrid
