摘要: 无融合生殖是一种不发生雌雄配子核融合而产生种子的一种无性繁殖过程。有些无融合生殖产生的种子是其母本的克隆,可以保留母本的基因型,因此无融合生殖可用于杂种优势的固定。尽管无融合生殖具有潜在的应用价值,但其形成机理十分复杂,表现在无融合生殖有多种表现形式,且受控的途径多样,遗传机制复杂,至今尚无定论,研究方法也多种多样。对近年来无融合生殖研究方面取得的进展进行了概述,旨在为深入研究无融合生殖提供参考。

Abstract: Apomixis is an asexual propagation through seeds in which embryo is formed without the nuclear fusion of male and female gametes. Since some resultant seeds of apomixis are clones of their maternal parent, they are identical to their maternal parent in genotype. Therefore, apomixis could be used in the fixation of heterosis. Apomixes has abundant potential application values, however, the mechanism for apomictic formation is very complicated, which was represented by multi-forms of apomixis that are controlled by varied pathways, the complicated genetic mechanism that has not been determined and finalized, and diverse methods of studying it. In recent years, apomixis has been studied in terms of linkage analysis. This paper outlines research progress on apomixis, aiming at providing references for in-depth study.

Key words: apomixis, genetic control, epigenetics
