Identification of Late Ripening Citrus Mutant, Ara-unshiu (Citrus unshiu), and Its Selectable Marker.

ABSTRACT: 'Miyagawa-wase' mandarin (Citrus unshiu Marc. cv. Miyagawa-wase early) is one of the most widely cultivated citrus varieties on Jeju Island in Korea. Mutation breeding is a useful tool for the induction of genetic diversity for the rapid creation of new plant variants. We previously reported the use of gamma irradiation for the development of new citrus varieties. Here, we report a new mutant, Ara-unshiu, with a unique late fruit ripening phenotype. We investigated the fruit morphological characteristics including weight, vertical/transverse diameter, peel thickness, hardness, and color difference, as well as sugar and acid contents of the Ara-unshiu compared to wild-type controls. We then used whole genome re-sequencing and functional annotation by gene ontolog
