摘要： 利用胡萝卜雄性不育系配制43个杂交组合,对其花型、根重、根长和根色等进行了调查分析.结果表明,胡萝卜正常花有3种类型,雄性不育花有4种类型,各不育系的遗传表现不同;单根重、根粗、根长性状在遗传中表现出较高比率的超高亲现象,根的颜色中黄心对于红心属于显性性状遗传,且具有积加效应.

Phenotypes of flowers and roots w ere invest-i g ated and analyzed. Most of the F1-hybrids show ed t ransg ressive inheritance in w eight, length, and w idth of single root . The yellow pith w as dominant to the red and had additive effect . The phenotypes of three fertile flow ers and four male-sterile f low ers w ere described in this paper.
