2014年中国北方向日葵列当生理小种分布研究报告

Research Report on Distribution of Physiological Race of Orobanche cumana Wallr. in Northen China in 2014

该调查目的是鉴定中国主要向日葵产区的列当生理小种分布情况。于2014年收集了来自内蒙古自治区、新疆自治区、甘肃省、吉林省和黑龙江省等主要产区的向日葵列当种子样本,并接种在抗列当向日葵鉴定系中(抗A到抗F)。研究结果发现我国主要向日葵产区列当生理小种有从A到F小种。

In order to identify the distribution and race composition of sunflower broomrape（Orobanche cumana Wallr.）, the seed samples were collected from the main sunflower production regions, including Inner Mongolia, Xinjiang Uygur Autonomous Region, Gansu Province, Jilin Province and Heilongjiang Province in northern China during 2014. The samples were evaluated against a set of differential lines. A wide distribution of O. cumana races from race A to F was observed.
