【 摘 要 】

An online web service system for a pedigree analysis was constructed. In this service, coefficients of parentage, inbreeding coefficients, numbers of ancestors in the pedigree, etc., are calculated through online. Crossing records of modern Japanese cultivars of rice, wheat, barley, potato, sweet potato and strawberry are also provided. Users can add thier own data to the record and use this system freely. Pedigree complexity of modern cultivars and pedigree relationship between them can be expressed as numerical data. Several informative results were obtained, although there is a restriction of computing time. Some modern rice cultivars in Japan have 500-1000 total ancestors and have a high coefficient of parentage to Koshihikari but they still have a high value to old cultivars, Norin 1 and Norin 22. Using this web system, complicated modern cultvars can be numerically expressed by numerals, which can be used for further analysis of the correlation with agronomic characters.
