香型水稻的遗传和育种现状

Inheritance and Breeding Actuality of New Quasi-aromatic Rice(Oryza sativa.L)

香型水稻在国际稻米贸易市场上占有重要的地位,成为当今科研热门课题之一,而香味是香稻最重要的品质特性。本文概述了香型水稻的遗传机制、香味基因的鉴定及香味基因分子育种利用等方面内容,简要介绍了香型杂交稻不育系和恢复系选育的进展,并分析和阐述香型杂交稻的选育及推广应用方面的进展。最后,针对当前香型水稻存在的问题,就如何深入开展香型水稻相关研究进行展望。

The cooking and eating quality of rice has attracted an increasing number of attentions recently.Aromatic rice falls into the specialty category of cultivated rice and is playing a vital role in the international paddy rice trade market.Fragrance is the most important quality trait in super rice whose research has become a hot subject.This paper reviewed the current situation on the the genetic study of aromatic rice,identification of fragrant gene,molecular breeding of fragrant gene.Then it expressed the correlation study of sterile line breeding and breeding restorer lines for quasi-aromatic Hybrid Rice.In the meanwhile,it explained the selection and extension of quasi-aromatic Hybrid Rice.The paper also analysed systematically about the existing problems in the research of aromatic rice.Also it maked the future expectation of the related research of aromatic rice.In conclusion,based on the related documents provided,we wish to offer some new angles in the deeply research of aromatic rice.
