中文摘要：

为了减少百合（Lilium）育种的盲目性,提高育种效率,本文主要以作者在百合育种工作中的结果和经验为基础,对现代百合品种与野生种的关系、百合组内杂交和组间杂交的差异、现代百合品种的育种途径、非整倍体百合的培育以及百合杂交中特殊现象的机制与新假说（即：百合倍性间杂交的胚乳中含有5个或以上相同基因组是其发育和杂交成功之关键）等方面进行了概述,为百合育种工作者提供有益的参考资料.

英文摘要：

In order to decrease the blindness and to increase the efficiency in lily（Lilium） breeding,mainly based on the author＇s research results and experience,this paper reviewed the relationship of lily cultivars and wild species,the difference between intra-sectional and inter-sectional hybridizations,the breeding ways of modem lily cultivars and aneuploid lilies,and the mechanism of special phenomena and a new hypothesis （i.e.,five same genomes of endosperm are essential for its development of triploid× diploid/tetraploid crosses of Lilium） of lily breeding.Hopefully,it would provide references for lily breeders.
