Genome-wide Association Analysis of Maturity Traits in Setaria italica Using 96kSNP Microarrays
Maturity traits are important factors influencing Setaria italica grain yield and quality.In order to elucidate the genetic mechanism controlling maturity traits and to lay the foundation for marker-assisted selection and breeding of desirable traits,nine maturity traits,namely number of mature stems,stilt position,spike shape,glume colour,glume colour,spike length,single spike weight,grain yield and total spike weight of 203 samples were investigated,and their genome rese-quencing was conducted.Genome-wide association analysis of single nucleotide polymorphism(SNP)markers(82 738 conserved loci were used)with nine maturity traits was performed and the results showed that the major SNPs associated with number of mature stems,stem attitude,spike shape,glume colour,glume colour,spike length,single spike weight,grain yield and total spike weight were distributed on all nine chromosomes.
