Research Advances in Genetic Map Construction and QTL Mapping of Ornamental Plants
摘要
Abstract
Ornamental plants are important horticultural crops,and their traits such as plant shape,flower color,flower form,flower fragrance,flowering habitat,prickle directly determine their ornamental and market value.Modern molecular breeding techniques are effective ways for rapidly developing new varieties.However,the lack of localization and mining of key genes for important traits greatly limits the application of these techniques in ornamental plants.Genetic map is a linear arrangement map of the relative positions of chromosomal or intra-genomic loci based on the recombination frequency of genetic markers.It is a crucial tool for studying the genetic laws and molecular mechanisms of complex traits in organisms,providing a foundation for the localization,identification and genetic mechanism analysis of key genes for traits,and offering theoretical and practical guidance for molecular breeding.In recent years,with the development of sequencing and molecular biology techniques,some progress has been made in genetic map construction and quantitative trait loci(QTL)mapping of ornamental plants,but it lacks systematic induction and summarization.This paper reviews the research progress on the construction of genetic maps and QTL mapping for important ornamental traits including plant shape,flower color,flower fragrance,petal number,and resistance-related traits in ornamental plants such as roses,orchids,and chrysanthemums,etc.It also discusses the existing problems,solutions and future development in the construction and application of genetic maps in ornamental plants,aiming to provide references and theoretical guidance for molecular breeding of ornamental plants.关键词
