不同马铃薯品种(系)在尼泊尔北部山区的适应性评价与筛选
Adaptability evaluation and screening of different potato varieties(lines)in the mountainous region of northern Nepal
摘要
Abstract
To identify the optimal potato varieties(lines)suitable to be planted in the northern mountainous areas of Nepal,12 potato varieties(lines),'Longshu 7''Longshu 10''Longshu 14''LK99''L0109-4''Yunshu 105''Yunshu 603''Ziyun 1''Mira''Qingshu 9''Emma 1'and'Emma 2',were introduced.'Rosita',the main locally planted variety,was used as a control(CK).Variety(line)comparison trials were conducted in the northern mountainous areas of Nepal from 2019 to 2021.The phenological period,agronomic traits,tuber traits,disease occurrence,organoleptic evaluation,yield traits,and yield performance were thoroughly studied.The comprehensive qualities of these 13 varieties(lines)were analyzed by Principal Component Analysis(PCA).The results showed that:All 13 potato varieties(lines)tested were able to mature;All varieties(lines)did not develop mosaic virus disease,bacterial wilt and early blight.'Yunshu 105''Yunshu 603'and'Ziyun 1'developed the lowest ratio of plants infected late blight and with disease index of 0;The average annual yield of'Yunshu 105'was 23.94 t/hm2,which is 72.73％higher than that of CK.The average annual yield of'Qingshu 9'was 21.01 t/hm2,which was 51.59％higher than that of CK;The organoleptic scores of steamed'Yunshu 105'was 82.6,it has aroma fragrant,high acceptance,and above moderate comprehensive evaluation;The top four comprehensive scores in the principal component analysis of tuber nutritional qualities were'Emma 1''Longshu 14''Longshu 7'and'Yunshu 105'.In summary,in terms of the current situation of lacking of high-yield variety in Nepal,'Yunshu 105'is optimal to be promoted in the northern mountainous areas of Nepal to improve production,'Qingshu 9'is suitable to be promoted as high-yield variety,'Emma 1''Longshu 14'and'Longshu 7'could be the alternative high-quality varieties for Nepal.关键词
