武威南部浅山区马铃薯新品种比较试验初报

Preliminary Report on the Comparison Experiment of New Potato Varieties in the Southern Shallow Mountainous Area of Wuwei

马铃薯生产中存在品种多、乱、杂的问题,是目前制约武威地区马铃薯产业发展的主要原因。为筛选出适宜武威南部马铃薯主产区种植的优质高产抗病马铃薯品种,解决武威地区马铃薯品种退化、抗病性减弱、产量低等问题,对引进的11个马铃薯新品种在武威南部浅山区进行了品种比较试验。结果表明,中晚熟马铃薯品种青薯9号和中熟马铃薯品种希森6号具有良好的适应性、丰产性和较好的抗病性,折合产量分别为61239.0、55861.5 kg/hm^(2),较对照品种陇薯10号分别增产21.91%、11.20%,可以作为当地主栽品种陇薯10号的替代品种在武威市南部浅山区马铃薯主产区推广。

The diversity,disorder,and mixture of potato varieties are the main factors currently restricting the development of the potato industry in the Wuwei area.To select high-quality,high-yielding,and disease-resistant potato varieties suitable for the main potato-producing areas in southern Wuwei,and to address issues such as variety degradation,weakened disease resistance,and low yield in the Wuwei area,comparative trials were conducted on 11 newly introduced potato varieties in the shallow mountainous areas of southern Wuwei.The results showed that the mid-late maturing potato variety Qingshu 9 and the mid-maturing potato variety Xisen 6 had good adaptability,high yield potential,and better disease resistance,with yields of 61239.0 and 55861.5 kg/ha,respectively.These yields represented an increase of 21.91%and 11.20%,respectively,compared to the control variety Longshu 10.They can serve as alternative varieties to the main locally cultivated Longshu 10 for promotion in the main potato-producing areas of the southern hilly region of Wuwei City.
