摘要： Rapeseed, one of the most important oilseeds worldwide, suffers from Sclerotinia stern rot. Glucosinolates are important because their hydrolysates are physiological functional to plant growth and development and are poisonous to livestock. However, previous reports only emphasized predominant glucosinolates and ignored trace glucosinolates. In our study a double haploid oilseed rape population was produced to study its interactions with two isolates of Sclerotinia sclerotiorum. Eleven glucosinolates were identified and evaluated for their roles in plant-parasite interactions. It was found that the 2-hydroxy-4-pentenyl glucosinolate induced susceptibility to one fungal isolate, whereas the 1-methoxy-3-indole-methyl glucosinolate induced resistance to the other. In contrast with previous reports, total glucosinolate was not correlated with Sclerotinia resistance, On the other hand, partial correlation was used to understand the association of the biosynthesis between different glucosinolates. The association between seed glucosinolate content and Sclerotinia resistance as well as the association between different biosynthesizing pathways of different glucosinolates is discussed.
