辽宁省马铃薯农家品种比较

Comparison of Potato Farm Varieties in Liaoning Province

[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 economic 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.
