国内外短低温桃的研究进展

Progress in Low-chilling Peach at Home and Abroad

短低温桃解决了南亚热带低海拔地区由于低温量不足而产生的桃不结果的问题;短低温桃的成熟期可提早2～3个月,提高桃的经济效益。美国、巴西为短低温桃的育种强国,早在1907年美国就培育出短低温桃,目前已培育出60多个短低温桃。国外引进的短低温桃大部分酸度高,在中国生产上无法大面积推广。中国短低温桃研究起步较迟,品种缺乏,国内近十年来通过省品种认定委员会认定的短低温桃品种只有2个。

The no-fruit of peach which was caused by the shortage of low temperature in the low altitude region at Southern subtropical could be resolved by the low-chilling Peach. The fruiting season of low- chilling peach could be predated by 2～3 months o That increased its benefit. The strong breeding countries of Peach in the world were America and Brazil. The first low-chilling peach was bred in America in 1907. There were above 60 varieties at present. The low-chilling peach from abroad could not be cultivated large-scalely .in China, because of high acidity. But the low-chilling peach breeding in China was very late, the variety was very lack, and there were two varieties which were identified by the committee of i- dentifying variety in our country.
