2021-2024年广东种博会参展南瓜及其代表性品种遗传多样性分析
Cucurbita Varieties Exhibited at Guangdong Seed Expo from 2021 to 2024 and Genetic Diversity Analysis of Their Representative Varieties
摘要
Abstract
To explore the market situation of pumpkin varieties and the development trend of breeding,statistical analysis of the varieties and exhibitors'information,and genetic diversity analysis of representative varieties were performed on the pumpkin varieties exhibited at the Guangdong Seed Expo from 2021 to 2024.The results showed that Miben-type pumpkins and chestnut-type pumpkins were the mainstream exhibited varieties,accounting for 71.42%of the total.The exhibitors were mainly concentrated in South China,North China,and East China,with South China being the most active region.There were obvious differences in the types of pumpkin varieties exhibited in different regions,showing diversity and imbalance.Genome resequencing and phylogenetic analysis were performed on 20 representative varieties exhibited in 2023.The results showed that these varieties covered two cultivated species of C.moschata and C.maxima.The genetic distance between species was significantly greater than that within species.Different types of pumpkin varieties exhibited obvious genetic clustering characteristics,and there were certain genetic differences among different types.The classification information provided by the exhibitors for some varieties was inconsistent with the results of the genetic evolution tree analysis.This study revealed the mainstream varieties in the pumpkin market,the geographical distribution of business entities,and the genetic diversity characteristics of varieties,providing a basis for the research of pumpkin germplasm resources,breeding improvement,and exploration of genetic relationships,which is helpful to promote the development of the pumpkin seed industry.关键词
