【摘要】 野生稻为水稻的野生近缘种,由于生长在自然环境中,未受到人为选择,其中蕴含着大量栽培稻已丢失的优异基因,是重要的基因宝库。长期以来,各国科学家不断努力挖掘野生稻的优异种质,探索其优异性状的内在遗传规律,用于水稻育种改良。从野生稻优异基因挖掘和利用的角度出发,系统回顾了近几年野生稻的不育性、抗病虫性以及抗逆性等优异性状的研究进展,并对现存的问题和采取的对策进行了探讨。更多还原

【Abstract】 Wild rice is wild relative of rice cultivars.Under natural environment,without artificial selection,wild rice contains a lot of excellent characters.Wild rice is valued as a unique source of genetic variation.Scientists discover excellent characters of wild rice,study inheritance of excellent characters.Starting from the perspective of excellent gene mining and utilization,the research advance of excellent characters of wild rice,such as sterility,insect resistance,disease and stress resistance were reviewed,the existing problems and countermeasures were discussed.更多还原
