Abstract:
The diseased rate , latent period, rate of disease development and disease rank of 63 soybean cul-tivars were evaluated after inoculation with strain Sa. Based on four resistant components , cluster analysiswas conducted , Results showed that 63 soybean cultivars were divided into 6 resistance types , namely immune , highly resistance , moderately resistance , moderate , moderately susceptibility and highly suscepti-bility. Besides immune , discrimination function formulas of 5 types of resistance cultivars were estab-lished. A synthetic disease index (SDI)by mean of diseased rate , disease rank and days from inoculation tomaximum disease index was given. Results of cluster analysis basically conformed to result of syntheticdisease index classification. Therefore , SDI can be used in evaluation of cultivars quantitative resistance tosoybean mosaic virus.
