Development of genomic and EST-SSR markers in radish (Raphanus sativus L.).

ABSTRACT: Radish (Raphanus sativus L.) belongs to Brassicaceae family and is a close relative of Brassica. This species shows a wide morphological diversity, and is an important vegetable especially in Asia. However, molecular research of radish is behind compared to that of Brassica. For example, reports on SSR (simple sequence repeat) markers are limited. Here, we designed 417 radish SSR markers from SSR-enriched genomic libraries and the cDNA data. Of the 256 SSR markers succeeded in PCR, 130 showed clear polymorphisms between two radish lines; a rat-tail radish and a Japanese cultivar, 'Harufuku'. As a test case for evaluation of the present SSRs, we conducted two studies. First, we selected 16 SSRs to calculate polymorphism information contents (PICs) using 16 radish cultivars and four other Br
