Introduction and Nutritional Quality Analysis of Main Grain Varieties of Dingxi Potato in Gansu Province

为丰富甘肃定西马铃薯主粮化种质资源和推广主粮化品种的种植,对比试的9个马铃薯品种采用随机区组比较试验,用Excel2003和Duncan新复极差法进行统计和方差分析比较品种农艺性状,用隶属函数值综合评价分析品种营养品质.结果表明,9个品种生物学性状良好,在定西地区种植均能成熟.根据抗旱性、产量性状、营养品质分析等指标综合筛选出陇薯8号、陇薯10号、定薯1号、陇薯3号等4个品种良好.

In order to enrich the germplasm resources of Dingxi potato in Gansu and to promote the cultivation of main grain varieties,the comparison of nine potato varieties was carried out by randomized block comparison test. Excel2003 and Duncan new complex range method were used for statistical and variance analysis. Agronomic traits were evaluated by the comprehensive evaluation of the membership function values. The results showed that the nine cultivars had good biological traits and were mature in Dingxi. According to drought resistance,yield traits,nutritional quality analysis and other indicators,four varieties including Yanshu 8,Yushu10,Dingshu 1 and Yushu3 were well selected.
