[目的]拓宽育种领域，积极挖掘辽宁省马铃薯资源，尤其是农家品种。[方法]在辽宁省收集3个马铃薯农家品种(农1、农2、农3)，对其产量、块茎品质及主要经济性状进行比较。[结果]农1产量较高，但是商品薯率较低，芽眼深；农3属于中熟品种，产量较对照早大白有所增高，但差异未达显著水平；农2属于中熟品种，较对照早大白增产37.8%，增产幅度明显，结薯较集中，商品性状好。[结论]农2可以在一季作区进行小面积种植示范。%[ Objective ] The aim was to broaden the breeding areas and actively develop local resources, especially potato farm varieties in Liaoning Province. [Method] Three potato farm varieties(Nong 1, Nong 2, Nong 3) were collected in Liaoning, yield, tuber traits and main e-conomic traits were compared. [Result] The yield of Nong 1 potato was higher, while marketable tuber percentage was lower and eye was deep;Nong 3 potato belongs to medium maturing variety, the yield was higher than control variety Zaodabai, but the difference was not significant;Nong 2 potato belongs to medium maturing variety, the yield was increased 37. 8% compared with Zaodabai, tuber setting was concentrated and commodity traits were good. [ Conclusion] Nong 2 can be planted and demonstrated in the small area of single cropping potato region.
