芸薹属蔬菜抽薹性状遗传机理研究进展

摘要

Plants' flowering and bolting were induced by vernalization in their early growth stage.This process resulted in the impossible forming of the leaf head. This phenomenon is known as premature bolting which has caused a great loss in vegetable production. The most effective solution to solve this problem is to develop bolting-resistant varieties. Research on genetic mechanism of bolting trait helps to breed bolting-resistant varieties. The essay summarizes the research progress on genetic mechanism,molecular marker and molecular mechanism of bolting trait in Brassica vegetables. It also discusses about the prospects of future research works, according to present research status.%植株在生长初期就通过低温春化,引起花芽分化及抽薹开花,以致植株不能形成叶球的现象称为先期抽薹,这给蔬菜生产造成了很大损失.选育耐先期抽薹品种是解决这一问题的最有效途径,掌握抽薹性状的遗传机理有助于耐先期抽薹品种的选育.本文对国内外有关芸薹属蔬菜抽薹性状的遗传规律、分子标记及抽薹分子机理的研究进行了综述,并结合目前的研究现状提出了今后的研究方向.
