摘　　要：对核桃无融合生殖研究的成果进行了归纳总结得出:很多核桃都具有一定的无融合生殖能力,无融合生殖是指不经过精卵融合即可形成胚从而进行种子繁殖后代的一种特殊的无性生殖方式,无融合生殖胚的形成没有父本的参与,其后代是母本基因型的完整克隆,因此是植物杂种优势固定与利用的一种最理想的途径,具有巨大的潜在利用价值,被誉为"无性革命".利用孤雌生殖开展核桃优良品种遗传纯化,可最大限度地缩短纯化周期,为林木遗传纯化开拓一条快捷、高效、实用的新途径。The article sums up the research outcomes of the walnut apomixes.The results showed that a large variety of walnut had some apoxmixis ability.Apomixis is a special asexual reproduction that plants can form embryo and produce progenies via seeds without sperm-egg fusion.Since apomictic embryo is a complete genetic clone of maternal parent without the participation of sperm.it is an ideal pathway to fix and utilize hybrid vigor and has unpredictable potential value in crop breeding,thus be called ＂the asexual revolution＂.The use of parthenogenesis to carry out genetic purification of fine varieties of walnut may be shortened to maximize the purification cycle,for the trees to open up a genetic purification of fast,efficient and useful new way.
