大理州大春马铃薯品种比较试验

Comparison Test of Potato Varieties for Spring Season in Dali Prefecture

为筛选出适宜大理州大春马铃薯生产所需的新品种,改变主栽品种单一局面,以‘合作88’为对照,对新选育的9个马铃薯新品种(系)进行了2年的品种比较试验。试验结果表明,‘200.3’高产且稳产,商品性好,晚疫病、早疫病抗性较强,适宜推广种植,可作为大理州大春马铃薯替代品种;‘12H14-5’商品性好,产量较高且稳产,晚疫病抗性较强,适宜于大理州大春种植,可进行进一步的评价、示范;‘207.3’商品性较好,产量较高,晚疫病、早疫病抗性较强,适宜大理州大春种植,但稳产性需进一步验证。

Nine potato varieties(lines)were evaluated using variety'Hezuo 88'as a control in two successive years under the spring season conditions in order to select new potato varieties adapted to the spring season and to improve simple structure of currently cultivated varieties in Dali Prefecture.The line'200.3'showed stable and high yield with high marketability,resistance to late blight and early blight,and could be an alternative elite variety for the spring season cultivation.'12H14-5'showed stable and relative high yield with high marketability,resistance to late blight,and good adaptation to the spring season cultivation,but need to be further evaluated and demonstrated.'207.3'showed relative high yield with higher marketability,resistance to late blight and early blight,and good adaptation to the spring season cultivation,but the yield stability need to be further evaluated.
