紫花苜蓿根腐病研究进展

紫花苜蓿是全世界最重要的豆科牧草,被誉为“牧草之王”,但苜蓿根腐病成为紫花苜蓿大面积推广的一个主要的限制因素。苜蓿根腐病的病原主要是镰刀菌,其中的尖孢镰刀菌、茄镰刀菌、燕麦镰刀菌等被认为是侵染根部的真菌中的优势种。生物技术是当前植物抗根腐病育种中的一个应用热点,它具有目的性强、育种效率高等优点,越来越受到人们的重视。

Research progress in root rot of alfalfa

Alfalfa,considered as the king of forage,is the most important legume in the world.However,the root rot of alfalfa has become a primary restraint of its wide utilization at present.The main pathogen of the root rot of alfalfa is from Fusarium,of which,F.oxysporum, F.solani and F.avenaceum are dominants in intruding roots.As a useful application of disease resistance breeding,with advantages of aim-orientation and high efficiency,biological technology has drawn increasing attention.
