Accumulation and characteristics of small fruit genetic resources? Yield characteristics of newly introduced varieties of blueberries in Isehara City Summery The purpose of this study was obtain basic materials for an investigation of the cultivation fitness of blueberry varieties in Isehara City, Kanagawa Prefecture. Thirteen varieties of northern highbush, 3 varieties of southern highbush, and 3 varieties of rabbit-eye blueberries were used. The following items were - 133 -
investigated: harvest season, crop yield, berry weight, changes in sugar weight during the harvest season, and individual survival rate. The superior results obtained for Baldwin blueberries, a variety of rabbiteye, indicate that it is a suitable variety for Isehara City in Kanagawa Prefecture. If a mix centered on this variety is selected so that the berries can be harvested continuously from June to September, Baldwin are considered more to be better than other rabbit-eye varieties of Brightwell or Briteblue because of their superior crop yield and berry weight. Among the northern highbush varieties the early season cultivars Spartan and Duke, the mid season cultivars Bluecrop and Berkeley, and the late season cultivar Dixi are thought to be suitable. Among southern highbush varieties, Sharpblue and Flordablue are thought to be suitable. - 134 -
