| Research Abstract |
Some grapes often cause a coloration disorder in southwest warm places in Japan. The most suitable temperature of the enzyme related to the coloration is 25 degrees Celsius, and the coloration of the grape skin begins at the higher temperature period in the year. As most cultivars require some chilling hours for breaking bud dormancy, a grape industry did not develop in the subtropical area well. Therefore the characteristics of the new grape cultivar 'kadainou R-1' was investigated in Okinawa and Kagawa, because this cultivar is the progeny of Japanese wild species Ryuukyuuganebu which has no bud dormancy and is superior in the coloration even under the high temperature condition.
The methodology of in vitro chromosome doubling was examined for improving common tetraploid cultivars with 'Kadainou R-1' and Ryuukyuuganebu. The shoot tip culture of male Ryuukyuuganebu has not been successful so far, and I could regenerate the plantlets for the first time.
