An important breeding target for persimmon is to achieve elite cultivars of the pollination constant nonastringent (PCNA) type. The RO2 SCAR marker has been established to identify the trait of Chinese PCNA type by Ikegami et al. [J. Jpn. Soc. Hort. Sci. 80 (2011)150-155]. Here, the informativeness of RO2 was tested in all Chinese PCNA types and two F-1 populations bred from crosses between a non-PCNA maternal parent and either a Chinese PCNA type or an androecious male parent. The RO2 marker was detected in ten Chinese PCNA types and six androecious genotypes, but not in any of the non-PNCA and Japanese PCNA types. The segregation behavior of RO2 in both F-1 populations was consistent with a 1:1 ratio as previously reported by Ikegami et al. The presence of the RO2 marker among androecious material indicates that they also have potential as donor of non-astringency trait of Chinese PCNA type. (C) 2012 Elsevier B.V. All rights reserved.
