脱毒马铃薯的商品性及增产效果试验初探

Preliminary report on marketability and yield-increasing effect of virus-free potato

对紫花851、中薯3号等马铃薯脱毒种薯与非脱毒种薯进行比较试验,结果表明:脱毒马铃薯种薯抗病性、商品性明显优于非脱毒种薯,脱毒品种能有效地减少块茎小薯率、露青薯率及裂薯率,产量也极显著地高于非脱毒种薯。

Comparative tests were conducted among virus-free potatoes （Zihua851, Zhongshu3） and non-detoxinic seed potato. The results showed diseases tolerance and marketability of virus-free potatoes were better than those of non-detoxinic seed potato. The rates of small tuber, crack and green peel of virus-free potatoes was lower and the yield was significantly higher than non-detoxinic seed potato.
