摘　　要：脱毒马铃薯费乌瑞它原原种在同等条件下,明显表现出大粒种薯比小粒种薯产量高,原原种大小2.0~2.5 g、2.5~3.5 g、3.5 g以上的处理产量分别为15 390、18 015、18 550 kg/hm2,与原原种大小1.0~1.5 g的处理（14880 kg/hm2）相比,增幅分别为3.4%、21.1%、24.7%。出苗率随种薯重量增加而显著增加,分别比原原种大小1.0~1.5 g的处理增加2.5%、12.5%、15.0%。薯块个数和薯重均随着种薯重量的增加而增加。Under the same conditions,it showed distinctly that large seeds of detoxified potato Favorita had a higher yield than small ones. Compared with 14 880 kg/hm2 under size of potato seeds was 1.0-1.5 g,size of potato seeds were 2.0-2.5 g,2.5-3.5 g,〉3.5 g had a yield of 15 390,18 015 and 18 550 kg/hm2,with an increase of 3.4% ,21.1% and 24.7% respectively.The rate of emergence increaseed significantly with the weight of potato seeds.Compared with the minimum size of potato seeds ,an increase of 2.5%, 12.5% and 15.0% had been found respectively.The number and weight of potatoes also increaseed with the weight of potato seeds.
