2017年河南省春季马铃薯新品种(系)引进及比较试验

Introduction and Comparative Test of New Spring Potato Cultivars(Lines) in Henan Province in 2017

以中薯13号为对照,对引进的6个马铃薯品种(系)进行比较试验。试验结果表明,N195和N108较对照增产3.94%～5.17%,商品薯率为71.84%～89.50%,综合性状优良,适宜在河南春季种植;N157产量最高,较对照增产23.30%,但商品薯率较低,为55.20%,需进一步试验筛选;NFJ6产量最低,但肉色好,可作为特色品系留作育种材料;N210和D613较对照减产5.82%～57.51%,薯块性状较差,不适宜在河南春季种植。

Six potato cultivars were introduced and the comparative test was conducted by using Zhongshu No.13as the control cultivar.The results showed that the yields of N195and N108were3.94%-5.17%higher that of the control cultivar,and their economic potato rates were71.84%-89.50%,so the two cultivars were suitable to be planted in spring in Henan province for their good comprehensive characters.N157had the highest yield,which was23.30%higher than that of control cultivar.However,N157had a low economic potato rate of55.20%,so it must be took part in further experiment.NFJ6had the lowest yield,but its flesh color was purple,so it could be reserved as the breeding material.The yields of N210and D613were5.82%-57.51%lower than that of control cultivar,and they had poor potato tuber characters,so they were not suitable to be planted in spring in Henan province.
