Abstract
Records of rice breeding for high palatablity in Fukuoka Agr.Res.Center were stored in a word-processor and spreadsheet system, which could be used easily by plant breeders. Multiple regression of palatability, combining ability in palatability, correlation between palatability and other traits in regional trials, correlation of several agronomic traits among different years or fertilizing levels and coefficient of parentage among breeding lines were computed. Cluster analysis based on the coefficients of parentage was also performed. The results showed that many valuable suggestions to make the rice breeding more efficient were obtained by analyzing breeding records using this simple data management system.
