摘　　要：对胡萝卜 2 0个亲本的小区产量等 11个性状 ,采用综合评分法及通径分析法进行分析。结果表明 ,参试的 4个母本不育系 ,4个父本自交系综合性状较好 ,分别为S8,S4 ,S2 ,S5和C94 3,C94 1,C972 ,C96 1。胡萝卜亲本选择选配时 ,应首先考虑单根重。其次考虑商品产量和收获时最大叶长 ,同时要兼顾抽苔率、黄心率。The methods of comprehensive characters and path analysis were adopted in 20 parents characters’anythsis of carrot (Daucus carota L ).The result indicated that four tested female sterile lines:S8,S4,S2,S5 and four male parents selfcross lines:C943、 C941、 C972、 C961 had better comprehensive character.It can be concluded that single root weight should be firstly concerned in parents selection, secondly concerning commercial quality and the largest harvested leaf length. Meanwhile, lower bolting rate, yellow pith rate and pith incl should also be concerned.
