摘　　要：以‘费乌瑞它’原原种、原种、一级种、二级种为试验材料,对其进行农艺性状评价,掌握‘费乌瑞它’不同级别脱毒种薯的生长表现。结果表明,各个级别种薯的生长期、植株性状、薯块性状等方面表现存在一定的差异,综合表现较好的是原种和原原种,植株性状好,病害少且薯块大,商品薯率高,产量高,其次是一级种,表现差的是二级种,生产上种植马铃薯在考虑到生产成本和经济效益的情况下,应选用原种和一级种作为种薯使用。To understand the growth performance of different levels of virus-free seed potato of‘Feiwuruita’,this study used nuclear stock,foundation stock,first-grade seed,and second-grade seed as experimental materials to evaluate their agronomic characteristics.The results indicated that there were no notable differences in the phenology,plant traits,and tuber traits among the tested materials.The nuclear and foundation stocks demonstrated superior overall performance,including favorable plant traits,fewer disease occurrences,larger tubers,a higher proportion of commercial-grade potatoes,and higher yields.The first-grade seed performed moderately well,while the second-grade seed exhibited poor performance.When cultivating potatoes,to balance production costs and economic benefits,nuclear and first-grade seeds are recommended as seed potatoes for commercial production.
