[Elektronische Daten] [Sogo Nishio, Norio Takada, Toshiya Yamamoto, Shingo Terakami, Takeshi Hayashi, Yutaka Sawamura, Toshihiro Saito] The Japanese chestnut (Castanea crenata Sieb. et Zucc.) has a pellicle that is difficult to peel, which increases the labor and cost for removing the pellicle from the nut during processing. Thus, a pellicle that is easier to peel has been an important objective of Japanese chestnut breeding programs. A newly released cultivar ("Porotan”) exhibits a unique, easily peeled pellicle. A previous study indicated that this trait is controlled by recessive gene p, and that several of the ancestors of Porotan (e.g., "Tanzawa” and 550-40) were P/p heterozygotes. Two F1 populations from intra-specific crosses of Japanese chestnut, Tanzawa (P/p) × Porotan (p/p) and 550-40 (P/p) × Tanzawa (P/p), were used for genetic mapping of the gene that controls this characteristic. A total of 11 simple sequence repeat (SSR) markers were obtained that showed significant linkages to the p gene, and genetic linkage maps for the region around the p gene were established. Pedigree analysis was conducted for eight ancestors of Porotan around the pellicle-peeling locus using graphical genotypes based on the 11 SSR loci. The two recessive p alleles and surrounding haplotypes of Porotan were inherited through different intermediate cultivars: one allele was derived from "Otomune” (P/p) via Tanzawa and the other was derived from Otomune via Tanzawa, "Kunimi” (P/p), and breeding line 550-40. A recombination event was found in the flanking region close to the p gene in Kunimi. Molecular identification of the easy peel pellicle trait will lead to marker-assisted selection and will greatly improve Japanese chestnut breeding.
