Genome‐wide association coupled gene to gene interaction studies unveil novel epistatic targets among major effect loci impacting rice grain chalkiness

2 days ago   |   By Wiley

Summary
Rice varieties whose quality is graded as excellent have a lower percent grain chalkiness of two percent and below with higher whole grain yields upon milling, leading to higher economic returns for farmers. We have conducted a genome‐wide association study using a combined population panel of indica and japonica rice varieties, and identified a total of 746 single nucleotide polymorphisms that were strongly associated with the chalk phenotype, covered 78 Quantitative Trait Loci regions. Among them, 21 were high‐value QTLs, as they explained at least 10 % of the phenotypic variance...
