河南省春露地马铃薯品种比较试验

以郑薯7号为对照,采用春播方式,在郑州对引进的7个马铃薯品种进行2 a品种比较试验,以期筛选出早熟、高产、抗逆性强,且适合河南地区推广应用的马铃薯新品种。试验结果表明,郑薯9号、中薯191、F00070综合表现较好,平均667 m^2产量分别为3 107.60、2 826.29、2 773.71 kg,分别比对照郑薯7号的2 720.26 kg/667 m^2增产14.24%、3.9%和1.97%,薯块椭圆形,薯皮光滑,芽眼浅,商品薯率分别为89.66%、76.44%和95.09%,较适合河南郑州地区春季露地示范推广种植。

Comparative Test of Spring Open Field Potato Cultivars in Henan Province

In order to screen out potato cultivars with the characteristics of high yield and early maturity, and suiting for popularizing and applying in Henan, 7 potato cultivars were introduced and the comparative test were conducted in spring in Zhengzhou for two years by using Zhengshu No.7 as control cultivar. The results showed that the comprehensive characters of Zhengshu No.9, Zhongshu No.191 and F00070 were good, and their average yields of 667 m^2 were 3 107.60, 2 826.29 and 2 773.71 kg, which were increased by 14.24%, 3.9% and 1.97% respectively compared to that the control (2 720.26 kg). The potato tuber of these three cultivars were oval shape with smooth cortex, shallow eye, and their commodity potato rates were 89.66%, 76.44% and 95.09% respectively, which were suitable for demonstrating and popularizing in spring open field in Zhengzhou district.
