甘薯抗线虫病的遗传育种研究

甘薯线虫病是危害甘薯的主要病害,危害甘薯的线虫种类主要是根结线虫和茎线虫.甘薯生产上主要采用综合防治方法进行防治,其中选育抗病品种最为经济有效.本文综述了根结线虫和茎线虫病的抗源筛选、抗性机制、抗性的遗传和抗病育种等方面的研究进展,并展望了甘薯抗线虫病育种.

Inheritance and Breeding for Resistance to Sweetpotato Nematodes

One of the major problems in sweetpotato production is the damage caused by nematodes. The nematodes that limit sweetpotato production are sweetpotato root-knot and rot-knot nematode. The intergrated methods are used to control the disease in sweetpotato production. Among them, the best efficient and economical way to controlling the disease is breeding of resistant varieties. The research progress of sweetpotato root-knot and rot-knot nematode on resistant germplasm screening, resistant mechanism, inheritance and breeding of resistance are reviewed in this paper. The perspective of breeding for resistance to nematodes has also been prospected.
