荞麦抗落粒性状研究现状及育种展望OA

Buckwheat is rich in balanced nutrition,rich in flavonoid bioactive substances,high in edible and medicinal value,and the market demand is increasing year by year.But in the cultivation of buckwheat,it is easy to drop seed,which seriously affects the yield of buckwheat.Seed dropping resistance breeding is one of the most effective ways to increase buckwheat yield,and relevant research has important production significance and is the focus direction of current research.In recent years,researchers have done a lot of research on the physiological mechanism of buckwheat seed dropping.With the development of molecular biology,it has become a hot research topic to analyze the molecular mechanism of the off-zone development and seed dropping phenomenon.The physiological mechanism of buckwheat seed dropping,molecular breeding for seed dropping resistance and related gene mining were reviewed in detail.On the basis of this,the research on seed breeding for buckwheat resistance to seed dropping was prospected,which provided ideas for breeding varieties with seed dropping resistance and ensuring high and stable yield of buckwheat in future.
