Use of modern tomato breeding germplasm for deciphering the genetic control of agronomical traits by Genome Wide Association study

摘要

Key message A panel of 300 tomato accessions including breeding materials was built and characterized with > 11,000 SNP. A population structure in six subgroups was identified. Strong heterogeneity in linkage disequilibrium and recombination landscape among groups and chromosomes was shown. GWAS identified several associations for fruit weight, earliness and plant growth.
