草莓作为重要的浆果类作物之一,其栽培面积和产量一直居于世界小浆果生产的首位,业已成为我国效益最好的农业产业。栽培草莓选育始于19世纪初的英国,我国草莓育种起步较晚始于20世纪50年代,本文按照时间节点介绍了国内外草莓育种历程及代表性草莓品种。八倍体栽培草莓基因组中亚基因组间存在高度同源性,到目前为止未组装出较为完整的参考基因组;二倍体森林草莓基因组经过多次修订具有较高的完整性和精密性。随着测序技术的发展,大量的草莓品质和抗性相关的分子标记被开发,这些标记也被应用于草莓育种项目中,大大提高了育种效率。我国草莓育种存在亲本遗传背景狭窄、育种方法单一等问题,针对这些问题本文提出了我国草莓育种未来方向和发展趋势。
Strawberry is one of the most important berry crops worldwide, and is always ranking first in cultivation area and yield harvest among the small berries. Nowadays the strawberry planting has become one of profiling agricultural industries in China. The breeding of cultivated strawberries began in England in the early 19th century, while it began in the 1950s in China. According to the timeline, the breeding history and representative varieties of strawberry at home and abroad were described in this paper. So far a relatively complete reference genome has not been assembled, due to the high degree of homology between subgenomes in the octoploid strawberry genome. The diploid strawberry (Fragaria vesca) genome has high integrity and precision after revision. With the development of sequencing technology, a large number of molecular markers related to strawberry quality and resistance have been developed. These markers have also been used in strawberry breeding program and greatly improved the breeding efficiency. There are some problems in strawberry breeding in China, such as narrow parental genetic background and single breeding method. In view of these problems, the future direction and development trend of strawberry breeding in China were reviewed.
