摘要
马铃薯疮痂病已成为马铃薯生产上四大主要病害之一。由于马铃薯种植面积的扩大,其危害也在加重,严重影响马铃薯种薯生产和商品薯销售。为更好地防治马铃薯疮痂病,筛选抗病品种,通过随机区组试验,比较了12份马铃薯品种的疮痂病病情差异及感病后的各品种产量差异。结果表明:克新28病情指数最小,为12.11,对疮痂病的抗性最高,但该品种商品产量不高。克新19与克新28的发病率之间无显著差异,但产量差异却极显著,综合品种表现以克新19为最优。
Potato scab has become one of the four major diseases in potato production.Due to the expansion of potato planting area,the harm is also aggravating,seriously affecting the potato seed production and commodity potato sales.In order to better control potato scab,through randomized block trials,the differences of the disease status of 12 potato cultivars and the yield differences of the tested varieties were compared.The rsults showed that among them,the disease index of Kexin 28 was the lowest,which was 12.11,which had the highest resistance to scab,but the yield of the breed was not high.Kexin 19 and Kexin 28 no significant difference between the incidence,but the yield difference was extremely significant,the performance of integrated varieties,the best performance of Kexin 19.
