山东春早熟马铃薯品种比较试验

Comparison experiment of Spring early-maturing potato varieties in Shandong province

【目的】了解春季露地种植的马铃薯主栽品种特性,促进山东马铃薯产业的发展。【方法】通过对"鲁引1号""中薯8号""XS-07yh-03""早大白""双丰5号""13ab7""13as2""科薯6号""泰山5号""泰山7号"10个早熟主品种引进,研究在春季露地栽培下,不同马铃薯品种农艺性状、产量和商品薯率等。【结果】花色除了"鲁引1号"和"科薯6号"品种外均表现为白色;皮色肉色除早大白品种外均为黄色;品种间单株块茎数差异不明显;平均单薯重以"XS-07yh-03"为最大,达95.5g;产量"泰山5号"最高,38256.0kg/hm2,其次"鲁引1号",为37900.5kg/hm2。"泰山5号"和"鲁引1号"的商品薯率也表现较高,分别为85.3%和83.8%。【结论】综合考虑商品薯率和产量,以"泰山5号"和"鲁引1号"表现最好。

[ Objective ]In order to understand the varietal characteristics of potato planted outdoor in the spring and promote the development of potato industry in Shandong province. [ Method ]Under cultivation in open field in spring, ten potato varieties （Luyin 1, Zhongshu 8, XS-07yh-03, Zaodabai, Shuangfeng 5, 13ab7, 13as2, Keshu 6, Taishan 5, Taishan 7） were tested for yield, agronomic traits commodity potato rate, et al.[ Result ]The colors of different varieties of potato （except Luyin 1 and Keshu 6） were white; skin colors （except Zaodabai） were yellow; the number of tubers per plant among several potato varieties was no signifi- cant difference; average tuber weight of XS-07yh-03 was the largest, up to 95.5g; yield of Taishan 5 was the highest for 38256.0kg/hm2, followed by Luyin 1 for 37900.5kg/hm2. In addition, commodity potato rate of Taishan 5 and Luyin 1 showed a high rate, is 85.3%, and 83.8%, respectively. [ Conclusion ]Considering commodity potato rate and yield of potato, Taishan 5 and Luyin 1 performed the best.
