为了解部分月季品种间抗病性差异的原因和筛选出抗黑斑病的月季品种,对北京地区的50个月季品种黑斑病发病情况进行观察和抗病性分类,分析影响月季黑斑病抗性的因素。结果显示:月季分为高抗品种群(HR)5个;中抗品种群(MR)15个;低抗品种群(LR)12个;感病品种群(CS)14个;严重感病品种群(SS)4个。攀援月季、粉红色系月季和三倍体月季抗性较强。试验结果对于月季抗病育种具有一定参考价值。
In order to understand the reasons for the difference in disease resistance among some rose varieties and to select the rose varieties resistant to black spot, the incidence of black spot disease in 50 months in Beijing was observed and the disease resistance was analyzed. Resistance factors. The results showed that there were 5 high resistance cultivars (HR), 15 medium resistance cultivars (MRs), 12 low resistant cultivars (LRs), 14 susceptible cultivars (CSs) and severe susceptible cultivars Group (SS) 4. Climbing rose, pink department rose and triploid rose is more resistant. The test results have certain reference value for the disease-resistant breeding of roses.
