不同生态条件下马铃薯品种的淀粉含量分析

把北方一作区的6个品种,中大1号、内薯7号、克新12号、东农303、延97-8和尤金分别种植在加格达奇、牙克石、克山、哈尔滨、延吉和本溪6个地点,对各品种在各地点的淀粉含量进行分析。结果表明:中大1号的淀粉含量最高,但在试验区域内其品种稳定性差,延97-8的淀粉含量较高,且在试验区域内的品种稳定性好;加格达奇地区种植马铃薯的淀粉含量均值最高,本溪为淀粉含量均值最低,淀粉含量随着纬度的降低而呈下降趋势。

Starch Content of Six Potato Varieties under Different Ecological Environments

Six potato varieties, Zhongda 1, Neishu 7, Kexin 12, Dongnong 303, Yan97-8 and Youjin, were evaluated for their starch content at six locations, Jiagedaqi, Yakeshi, Keshan, Harbin, Yanji and Benxi, in Northern One Cropping Region of China. Zhongda 1 showed highest starch content, but poor stability. Yan97-8, though, ranked in the second place in starch content, it had no significant difference from Zhongda 1, and was with better performance of stability. Potatoes grown in Jiagedaqi had highest starch content, whereas in Benxi they were lowest in starch content, showing a trend that potato starch content decrease with decreasing in latitude.
