Genome-wide association study of kernel colour traits and mining of elite alleles from the major loci in maize.

ABSTRACT:

Background

Maize kernel colour is an important index for evaluating maize quality and value and mainly entails two natural pigments, carotenoids and anthocyanins. To analyse the genetic mechanism of maize kernel colour and mine single nucleotide polymorphisms (SNPs) related to kernel colour traits, an association panel including 244 superior maize inbred lines was used to measure and analyse the six traits related to kernel colour in two environments and was then combined with the about 3 million SNPs covering the whole maize genome in this study. Two models (Q + K, PCA + K) were used for genome-wide association analysis (GWAS) of kernel colour traits.

Results

We identified 1029QTLs, and two SNPs contained in those QTLs were located in coding regions of Y1 and R1 respectivel
