烤烟品种资源抗黑胫病品种综合评价

 黑胫病是主要的烟草病害之一,本文主要对现有的400多个烤烟种质资源材料中的213个进行抗黑胫病鉴定,结果为高抗黑胫病的品种17个,占7.98%,中抗的60个,占28.17%,抗的48个,占22.54%. 高感、中感和感病的品种各为7个、27个和47个。同时还对高抗黑胫病的品种进行综合评价,推荐用于烤烟大面积生产和优质、多抗烤烟新品种的选育中,以提高烤烟品种资源的利用率。

Comprehensive Evaluation of Flue-cured Tobacco Genetic Resource′s Resistance to Black Shank

Black shank is one of the important tobacco disease. The resistant evaluation to black shank was conducted on 213 varieties out of 400 flue-cured tobacco genetic resource collected presently. The results showed that there were 17 high resistance, 60 moderate resistance and 48 resistance to black shank and the percentages accounted for 7.98%,28.17% and 22.54% respectively. The number of varieties for high susceptive moderate susceptive and susceptive was 7,27 and 47 each. Mearwhile, the comprehensive evaluation was carried out among the high vesistance varieties in order to find out the suitable varieties for tobacco production and breeding and increase the ultilization efficiency of flue-cured tobacco genetic resource.
