Evaluation and Screening of Medium-maturing Potato Varieties in Dry Region of Central Gansu
摘要
Abstract
Eleven potato germplasm materials were introduced,and their phenological period,agronomic traits,tuber traits,yield traits,and qualities were studied using'Favorita'as a control in order to select new medium-maturing potato varieties suitable for planting in Dingxi City.A semi-film-covered single-ridge double-row planting method was adopted,with randomized block arrangement.The growth period of'Beifang 013','Beifang 016',and'Jintongshu 3'exceeded 100 days,while the growth period of the other varieties were less than 100 days.The Berry-setting ability of'Qinshu 107','Qincaishu 1','Mengwushu 4',and'Zhongshuzao 45'was weak,with a tuber number of 5.0-14.2 per plant,a tuber yield of 440-1 890 g per plant,and a tuber weight of 84.6-244.0 g.The dry matter content ranged from 14.6 to 26.8 g/100 g,with crude starch content at 9.07%-19.99%,protein content at 1.60%-2.51%,vitamin C content at 13.5-24.2 mg/100 g,and reducing sugar content at 0.10%-0.49%.The yields of'Beifang 016','Longshu 25',and'Mengwushu 4'were 57 936,54 153,and 46 711 kg/ha,respectively,which were 114.83%,100.80%,and 73.21%higher than those of the control variety,respectively.'Beifang 016','Longshu 25',and'Mengwushu 4'demonstrate superior comprehensive performances in this region and hold significant potential for promotion and application.关键词
