西瓜遗传图谱构建和基因定位研究进展

Research progress on genetic map construction and gene mapping for watermelon

西瓜是一种在世界范围内广泛种植的园艺作物,中国是世界上最大的西瓜生产国和消费国,对西瓜遗传育种的研究具有重要意义。遗传图谱是进行基因定位、图位克隆、分子标记辅助育种的重要工具,并为分子生物学的深入研究提供了基础。近年来,随着高通量测序技术和分子标记的发展,西瓜遗传图谱研究取得了很大进展,基于不同遗传背景的西瓜遗传图谱陆续发表,极大地促进了西瓜基因组学和分子遗传育种的发展。笔者总结了近年来国内外西瓜遗传图谱构建和基因定位的研究进展及应用,并探讨了目前西瓜遗传图谱构建方面存在的主要问题及今后的研究趋势。

Watermelon is a horticultural crop widely cultivated around the world. China is the largest producer and consumer of watermelon. The genetic breeding research of watermelon is of great significance. Genetic map is an important tool for gene mapping, map cloning, molecular marker-assisted breeding, and provides a basis for further research in molecular biology. In recent years, with the development of high-throughput sequencing technology and molecular markers, the research on watermelon genetic map has made great progress. Many genetic maps based on different genetic background have been constructed, which greatly promoted the development of watermelon genomics. This paper reviewed the research progress and application of watermelon genetic map construction and gene mapping in recent years, and discussed the main problems and future research trends of watermelon genetic map construction.
