2012年在湖南醴陵市油菜黑霉病果上经镜检和病种分离检出链格孢(Alternaria spp.),其后检测了36个品种的种子带菌情况,华湘油12号带菌率最高(51%)。镜检结果发现链格孢菌有2种,rDNA-ITS序列分析表明,它们分别是芸薹生链格孢(A.brassicicola)和芸薹链格孢(A.brassicae);未检测到萝卜链格孢(A.raphani)。36个品种中芸薹生链格孢分离频率最高的是华湘油12号(66%),且全为芸薹生链格孢,而芸薹链格孢以常油杂61为最高(15%),且全为芸薹链格孢。禾盛油868种子上未检测到链格孢菌。

Alternaria spp.was detected on rapeseed siliques with black mold collected from Liling city of Hu-nan Province under microscope in 2012.Among 36 tested commercial rapeseed cultivars,Huaxiangyou 12 had the highest Alternaria contamination frequency (up to 5 1%)by microscope on seed detection.Isolates were proved to be A.brassicicola and A.brassicae respectively by rDNA-ITS sequence analysis.Huaxiangyou 12 had the highest i-solation rate (66%)and only carried A.brassicicola.Changyouza 6 1 had the highest A.brassicae isolation frequen-cy (15%).No A.raphani was isolated.Heshengyou 868 had neither of the Alternaria spp.
