This study was done in order to investigate the changes in quality of Cheonggukjang for soybean cultivars during fermentation. Cheonggukjang of 14 cultivars that were inoculated with Bacillus subtilis 15893 was produced, and, then, it was measured for hardness, proximate composition, amino nitrogen, enzyme activity, and total aerobic bacteria counts. In a raw bean, the highest hardness value was 16,975 g from Sunyu. In a steaming bean, Jangwon had the highest hardness value and the lowest aerobic bacteria counts of forty-eight hours fermented Cheonggukjang. Saedanbaek, whose protein contents was highest in raw bean, was also highest in Cheonggukjang. The amino nitrogen content of twenty-four hours fermented Cheonggukjang was highest in Saeol and Sunyu while forty-eight hours fermented Cheonggukjang was highest in Singi, Daol, and Milyang 231. In the protease activity, Saedanbaek had the highest and total aerobic bacteria count that were either increased or held as time went on ; twenty-four hours fermented Cheonggukjang was highest in Milyang 231 and Keunol while forty-eight hours fermented Cheonggukjang was highest in Chunsang.

Bacterial pustule (BP) caused by Xanthomonas axonopodis pv. Glycines (Xag) is one of major bacterial diseases in soybean in Korea. BP causes premature defoliation and reduction in seed yield and quality. To identify soybean genotypes resistant to bacterial pustule, 58 domestic soybean cultivars for fermented soy sauce and tofu were screened. Among them 8 cultivars showed strong resistant phenotype to BP, while 7 cultivars showed susceptible phenotype. In order to determine genetic relationship between domestic soybean cultivars, seven bacterial pustule-linked simple sequence repeat (SSR) markers were selected. All of SSR markers showed polymorphism. A total 32 alleles were detected and the number of alleles per locus varied from 2-6 with an average of 4.57. The Polymorphic Information Content (PIC) values ranged from 0.513 to 0.795 in 7 loci with an average of 0.622. The genetic similarity between cultivars was analyzed with Unweighted Pair Group Method with Arithmetic mean (UPGMA) clustering. This analysis divided the cultivars into 4 major groups. A number of strong resistant and susceptible cultivars to BP were belonged to group IV and group III, respectively. In addition, 7 SSR markers successfully distinguished 56 of the 58 domestic soybean cultivars, indicating the effectiveness of BP-linked SSR markers in variety identification. The results could be useful information to discriminate soybean genotypes and help in developing elite soybean cultivars resistant to BP.
