Fund:This study was supported by the Natural Science Foundation of Jiangsu Province of China (BK20141291), the Jiangsu Province Self-innovation Program [CX (13)5073], the Key Research and Development Program of Jiangsu Province (Modern Agriculture) (BE2015363), and the Project Funded by the Priority Academic Program Development of Jiangsu Higher Education Institutions AbstractFifty indica-japonicaspecific SSR markers were employed to genotype 86 conventional japonica rice cultivars mainly planted in Jiangsu province and 41 loci showed polymorphism among them. After amplifying in 86 rice varieties, a total of 113 alleles were detected at the 41 SSR loci, and the allele number ranged from two to six, with an average of 2.76 in each locus. Polymorphism information content (PIC) value of these 41 SSR markers ranged from 0.02 to 0.84, with an average value of 0.48; Nei’s expected heterozygosity value of the 41 markers ranged from 0.02 to 0.68, and the average value was 0.37. Based on the coefficient index ranged from 0.72 to 1.00, we divided the 86 cultivars into three groups by UPGMA. The analysis of taste quality traits investigated under different environments indicated that the taste quality of conventional japonica rice cultivars in Jiangsu was correlated with the genetic clustering. Under long-day (LD) condition, the amylose content (AC) and protein content (PC) manifested a tendency of group I > group II > group III, while the taste value (TV) was opposites. And under short-day (SD) condition, taste quality traits of group II and group III varied significantly compared with that under LD condition, while the traits of group I had no significant change. The results indicated that the main cultivars grown in Jiangsu have a general taste quality and narrow genetic background, broadening the genetic basis is an important approach to breed japonica rice cultivars with environment- insensitivity and good eating quality.
