Practical marker-assisted selection using two SCAR markers for fruit astringency type in crosses of ‘Taiten’×PCNA cultivars in persimmon breeding

Pollination-constant, non-astringent (PCNA) type persimmons (Diospyros kaki Thunb.) steadily lose fruit astringency and are more desirable than other types of persimmons. The PCNA/non-PCNA trait is qualitatively controlled by AST/ast alleles at a single locus. Persimmons are hexaploid, and PCNA of Japanese origin and non-PCNA genotypes are denoted as aaaaaa and A-----, respectively, if AST gene denotes A and ast gene denotes a. ‘Taiten’ is an...
