Drought-resistant Genotypes Selection of Yunnan Potato Resources

Thirty various potato strains were collected and breeded in the laboratory for many years.Control was Xuanshu 4 which was larger production in Xuanwei.In Agricultural Center of Xuanwei potato varieties，drought-resistance，high yield and stability of potato genotypes were evaluated.At last，appropriate local potato varieties were selected，which were drought-resistant and high yield.Results showed that taking root pulling force and yield as main technical parameters，drought-resistance of 05-290，05-363，S03-3276，Shepody，05-287，04-016，05-188，Xuanshu 5，05-225 and Lishu 200202 were higher than that of control，they were drought-resistance varieties.
