马铃薯是我省五大作物之一,在“千亿斤粮食产能工程”项目中将会发挥举足轻重的作用,具有很大的增产潜力。但目前随着马铃薯种植代数的不断增加,品种混杂退化的现象越来越重,影响了马铃薯的产量,平均单产仅为世界先进国家的35%。因此,研究和解决马铃薯混杂和退化的问题迫在眉睫。 Potato is one of the five major crops in our province. It will play a decisive role in the project of “100 million kg of grain production capacity project” and has great potential for increasing production. However, with the continuous increase of potato algebra, the phenomenon of hybrid degeneration is more and more serious, affecting the yield of potato. The average yield is only 35% of the advanced countries in the world. Therefore, it is imminent to study and solve the problem of potato miscibility and degradation.
