柑桔杂交育种中,由于多胚的干扰很难得到真正的杂种。采用单胚柑桔为母本是获得杂种苗的有效途径。以往柑桔杂交育种常用的是克里迈丁、王柑等少数几个类型。随着育种目标的不同,需要多种多样的单胚柑桔。1975年,我所资源组发表了《柑桔单胚类型的调查》(《柑桔科技通迅》,1975年 In citrus cross breeding, it is hard to get real hybrids due to the interference of multiple embryos. The use of single embryo citrus as the female parent is an effective way to obtain hybrid seedlings. In the past citrus hybrid breeding is commonly used in a small number of types such as Krimeidin, Wang Gan. With the different breeding goals, a variety of single embryo citrus is needed. In 1975, our resource group published the “Survey of Types of Citrus Singletons” (Citrus Science and Technology Newsletter, 1975
