摘要： 对胡萝卜20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C₉₄₃，C₉₄₁，C₉₇₂，C₉₆₁。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、髓指数较低的材料。

Abstract: 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.
