Abstract:
Eggplant is an important horticultural crop and one of the most widely grown vegetables in the Solanaceae family. Eggplant fruit-related agronomic traits are complex quantitative traits with low efficiency and long cycle time for traditional breeding selection. With the rapid development of high-throughput sequencing technology and bioinformatics tools, genome-wide association study (GWAS) has shown great application potential in analyzing the genetic rules of complex agronomic traits related to eggplant fruits. This paper first reviews the progress of genome-wide association analysis in eggplant fruit shape, fruit color and other fruit-related agronomic traits. Subsequently, aiming at the problem of missing heritability, which is common in the genetic studies of eggplant quantitative traits, this paper puts forward the development strategies of eggplant GWAS in the future based on the hot spots of application of four GWAS strategies in the research of agronomics traits related to eggplant fruits. Lastly, the application of GWAS strategy in the field of eggplant molecular breeding is expected to provide a theoretical basis and reference for the future use of GWAS to analyze the genetic basis of various eggplant fruit-related traits and to select fruit materials that meet consumer needs.
摘要:
茄子是一种重要的园艺作物,也是茄科植物中种植最广泛的蔬菜之一。茄子果实相关农艺性状是传统育种选择效率低、周期时间长的复杂数量性状。随着高通量测序技术和生物信息学工具的快速发展,全基因组关联研究(GWAS)在分析与茄子果实相关的复杂农艺性状的遗传规律方面显示出巨大的应用潜力。本文首先综述了茄子果实形状全基因组关联分析的研究进展,果实颜色和其他与果实相关的农艺性状。随后,针对遗传力缺失的问题,这在茄子数量性状的遗传研究中很常见,本文针对4种GWAS策略在茄子果实农艺性状研究中的应用热点,提出了未来茄子GWAS的发展策略。最后,GWAS策略在茄子分子育种领域的应用有望为今后利用GWAS分析茄子各种果实相关性状的遗传基础,筛选满足消费者需求的果实材料提供理论依据和参考。
