摘要
为解决甘肃省乃至西北地区马铃薯专用品种缺乏的问题,天水市农业科学研究所以晋薯 11 号为母本、天薯 9 号为父本杂交,利用常规杂交育种技术选育出了晚熟鲜食菜用型马铃薯新品种天薯 19 号.该品种在2019-2020 年进行的国家马铃薯西北晚熟组区域试验中,2 a 18 点(次)平均折合产量为 32 490.0 kg/hm2,较对照品种陇薯 6 号增产 3.0%.该品种生育期 119 d左右,薯块卵圆形、黄皮黄肉、芽眼少而浅.薯块品质优良,鲜薯块茎含干物质204 g/kg、淀粉 166 g/kg、维生素C 547 mg/kg、粗蛋白 22.1 g/kg、还原糖 3.5 g/kg.适宜在甘肃中东部、宁夏中南部、青海东部及生态类似区种植.
Abstract
In order to address the issues of special potatovarieties shortagein Gansu Province and even in Northwest China,a latematuring vegetable potato variety Tianshu 19 was bredby Tianshui Agricultural Research Institute by conventional hybrid breeding techniques using female parent Jinshu 11 and male parent Tianshu 9.From 2019 to 2020,datafrom the regional experiment of late maturing group of potatoes in the northwest showed that the average yield from 18 points(times)in 2 a was 32 490.0 kg/ha,which increased by 3.0%compared to the control variety Longshu 6.It is a late maturity variety,the total growing period is 119 d.The tuber shape is elliptic,with yellow skin and fleshcolor,fewerand shallow buds.The variety possesses ideal nutritious qualities with contents of dry matter,starch,vitamin C,crude protein and reducing sugar of 204 g/kg,166 g/kg,547 mg/kg,22.1 g/kg and 3.5 g/kg,respectively in tubers.Itis suitable for planting in central and southern Gansu,central and southern Ningxia,eastern Qinghai,and other areas with similar ecological conditions.
