甘蓝型油菜诱发孤雌生殖单倍体遗传育种研究述评

四川大学植物遗传实验室于1976年首次报道了甘蓝型油菜诱发孤雌生殖单倍体研究的初步结果。在其后的20年间,该实验室与校内外的一些单位协作,对甘蓝型油菜诱发孤雌生殖单倍体,进行了系列的遗传学理论研究,并将诱发孤雌生殖单倍体技术初步应用于甘蓝型油菜遗传育种,取得了一些进展,选育出了3529×奥罗、3529×瑞士、3529×非12等产量较高的杂交油菜组合。本文扼要地述评了甘蓝型油菜诱发孤雌生殖单倍体的遗传理论研究和遗传改良的试验结果,并对其在遗传育种中的应用进行了讨论。

A review of systematic genetic studies on induced parthenogenetic haploids in Brassica napus

Researchers in Laboratory of Plant Genetics, Sichuan University, first reported the production of induced parthenogenetic haploids in rapeseed in 1976. In the next 20 years since then, the authors and coworkers carried on systematic studies on biological mechanism and genetic improvement of induced parthenogenetic haploids. They obtained higher-yielding hybrid combinations, such as 3529×Oro and 3529×Swiss in B. napus. In this brief review, systematic studies of induced parthenogenetic haploids in B. napus were discussed, and further studies were suggested.
