综述了国内无核柑桔类型选育研究进展。通过芽变、实生选种及诱变育种等手段，我国已先后获得了１１９个无核或少类类型的柑桔品种（品系），涉及柑桔属的主要栽培种类和金柑属、黄皮属。芽变选种和实生选种为获得无核或少核类型的有效途径。大多数无核变异与花粉育性下降有关，胚囊败育、倍性变异及自交不亲和也是造成无核的原因。细胞工程技术为培育无核柑桔类型开展了一条新途径。 The research progress of type selection of non-nuclear citrus in China was reviewed. By means of bud mutation, seed selection and mutagenesis breeding, 119 kinds of citrus cultivars (lines) of non-nuclear or less type have been obtained in China. The main cultivars of citrus are related to kumquat, . Bud mutation selection and seed selection in order to obtain a nuclear-free or less effective way of nuclear types. Most of the non-nuclear mutation associated with decreased fertility, embryo sac abortion, ploidy variation and self-incompatibility is also caused by non-nuclear reasons. Cell engineering has taken a new approach to cultivating seedless citrus types.
