采用室内苗期接种鉴定和田间鉴定方法测定了青海省14个主要蚕豆品种(系)对根腐病的抗病性。结果表明:中抗品种(系)有8个,中感品种(系)6个,分别占总参试品种(系)的42.9%和57.1%,这与田间鉴定试验结果基本一致。应用室内苗期鉴定蚕豆根腐病抗性结果准确、速度快,而且不受环境条件限制,可作为蚕豆根腐病抗性快速鉴定的方法。
The resistance to root rot of 14 major broad bean varieties (lines) in Qinghai Province was determined by inoculation and field identification in laboratory. The results showed that there were 8 Zhonghua resistant cultivars (lines) and 6 susceptible cultivars (lines), accounting for 42.9% and 57.1% of the total cultivars (lines), respectively, which was basically the same as the field test. The application of indoor seedling identification of broad bean root rot resistance results accurate, fast, and free from environmental conditions, can be used as a method of rapid identification of broad bean root rot resistance.
