\uff11\uff0eBreeding and utilization of lower-chilling peach\u3000<\/strong><\/h2>\n\n\n\n

\u3000Forcing culture of peach under plastics is intended to ensure early shipping of production aimed at obtaining a higher market value. Usually, peach growers start forcing after attaining 900 chilling hours required by the high-chill cultivars. For achieving earlier forcing, lower-chilling peach with a high tasting quality would be necessary. Therefore, we bred a new cultivar named \u2018KU-PP1\u2019 and \u2018KU-PP2\u2019 that contained these traits by crossing Japanese high-chill and introduced low-chill cultivars. Currently we investigate effective methods for forcing culture with these cultivars.\u3000<\/strong><\/p>\n<\/div>\n\n\n\n

\uff12\uff0e Breeding of self-compatible Japanese plum<\/strong><\/h2>\n\n\n\n

  Most commercial cultivars of Japanese plum are self-incompatible and cross-compatible cultivars need to be interplanted. Thus, information about S<\/em>-haplotypes of each cultivar is important. We demonstrated that the S<\/em>-RNase genes of Japanese plum could be amplified effectively by S<\/em>-RNase gene-specific primers, and identified 14 different S<\/em>-RNase genes. In addition, we revealed the involvement of the Se<\/sup><\/em>-haplotype in self-compatibility in Japanese plum and developed the Se<\/sup><\/em>-RNase gene-specific primer. Currently, we are breeding self-compatible Japanese plum  cultivars with good fruit quality.<\/p>\n<\/div>\n\n\n\n

\uff13\uff0e Regulation of fruit set of sweet cherry in warm region<\/strong><\/h2>\n\n\n\n

\u3000<\/strong>Poor fruit set due to physiological fruit drop have become serious problems preventing stable production of sweet cherry in warm regions. Under controlled conditions, we demonstrated that the fruit set rate decreased markedly due to the rapid degeneration of the embryo sacs when the trees were exposed to high temperatures above 20\u2103, and that gibberellin may be involved in this phenomenon. We also found that extremely high temperature in summer reduced photosynthesis and cause early defoliation, which result in low fruit set rate in the following spring. We have developed several methods to improve fruit set in warm regions.<\/p>\n<\/div>\n\n\n\n
