马铃薯是我省三大粮食作物之一,历年种植面积达400万亩左右,仅次于小麦、玉米。因其产量高,适应性广,故在我省农业生产和人民群众生活中占有重要地位。随着科学研究的进步和深加工技术的发展不仅会成为重要的工业原料,而且其食物制品越来越受到广大消费者的普遍欢迎。近年来,由于病毒病的广泛传播和复合侵染,马铃薯品种“退化”问题日趋严重,已成为当前生产上的突出问题。尽管釆用茎尖脱毒的方法对解决当前生产用种问题具有一定的意义,但由于脱毒本身存在的局限性(如易重新感染病毒,感染后“退化”速度相对加快,晚疫病更加恶化,成本高等等),也就决定了抗病
Potato is one of the three major grain crops in our province. The annual planting area is about 4 million mu, second only to wheat and corn. Because of its high output and wide adaptability, it occupies an important position in the agricultural production and people’s livelihood in our province. With the progress of scientific research and the development of deep processing technology, not only will it become an important industrial raw material, but also its food products will be more and more popular among consumers. In recent years, the problems of “degeneration” of potato varieties have become more and more serious due to the widespread spread of virus diseases and compound infection, which has become a prominent issue in current production. Although the precautionary approach to stem-tip detoxification is of some significance to solve the current problem of production use, due to the limitations of detoxification itself (such as easy re-infection of the virus, the rate of “degeneration” after infection is relatively faster and the late blight is aggravated , High cost, etc.), also decided to fight disease
