湖南春马铃薯品种比较试验

通过对8个马铃薯品种的抗性、商品性、品质、产量等特性的比较试验,结果表明:鲁引、9903、中薯3号、中薯2号分别比东农303增产25.46%、19.09%、9.59%、5.67%,它们抗性强、综合性状表现好,值得推广。大西洋的抗性好、干物质含量高、还原糖含量低,是很好的值得推广的加工品种。诺兰的抗性差、产量低,但干物质、淀粉含量高。

A Comparative Experiment of Spring Potato Varieties in Hunan Province

Characteristics including resistance, commodity, quality and yield of 8 potato varieties were tri- aled and compared. The results showed that the yields of the varieties Luyin, 9903, Zhongshu No 3, and Zhong- shu No 2 increased, respectively, by 25.46%, 19.09%, 9.59% and 5.67% compared to the variety Dongnong 303 which is the main variety cultivated in Hunan now; the four varieties had strong resistance and good integrated characteristics and could be extended and cultivated in Hunan to replace the variety Dongnong 303. The variety Atlantic which had strong resistance, high dry mater content and low reducing sugar content was a good process- ing variety. The variety Norland had poor resistance and low yield, but it had high dry mater and starch content.
