马铃薯产业是甘肃省六大特色产业之一,为了选育出适宜甘肃省干旱半干旱生态区种植的淀粉加工专用型马铃薯品种,天水市农业科学研究所以C-71为母本、庄薯3号为父本,利用常规杂交育种技术历经10 a成功选育出晚熟高淀粉马铃薯新品种天薯16号。在2017 — 2018年国家马铃薯西北晚熟组区域试验中,天薯16号平均折合产量30 448.1 kg/hm2,较对照品种陇薯6号(26 024.2 kg/hm2)增产17.0%。天薯16号生育期120 d左右。薯块卵圆形,淡黄皮淡黄肉,薯皮光滑,芽眼浅。块茎干物质含量216.0 g/kg、淀粉含量185.0 g/kg、粗蛋白含量22.4 g/kg、Vc含量276 mg/kg、还原糖含量3.7 g/kg。中抗晚疫病、马铃薯X病毒病和马铃薯Y病毒病。适宜在干旱半干旱、高寒阴湿及二阴山区的甘肃中东部、宁夏中南部、青海东部春季种植。

[Abstract]
Potato industry is one of the six characteristic industries in Gansu Province. To develop a starch-processing-oriented potato variety suitable for arid and semi-arid ecological areas in Gansu, the Tianshui Agricultural Research Institute used C-71 as the female parent and Zhuangshu 3 as the male parent, and successfully bred a new late-maturing high-starch potato variety Tianshu 16 through conventional hybridization over 10a. In the 2017 to 2018 national northwest regional experiment for late-maturing potatoes, Tianshu 16 had an average yield of 30 448.1 kg/ha, which was 17.0% higher than that of the control variety Longshu 6 (26 024.2 kg/ha). The growth period of Tianshu 16 is about 120 d. Tubers are ovoid, with light yellow skin and flesh, smooth surface, and shallow eyes. The tubers contain 216.0 g/kg dry matter, 185.0 g/kg starch, 22.4 g/kg crude protein, 276 mg/kg vitamin C, and 3.7 g/kg reducing sugars. It shows moderate resistance to late blight, potato X virus, and potato Y virus. This variety is suitable for spring planting in arid and semi-arid, alpine humid, and shady mountainous areas in the central and eastern Gansu, southern and central Ningxia, and eastern Qinghai.
