Genetic loci determining potato starch yield and granule morphology revealed by genome-wide association study (GWAS).

ABSTRACT:

Background

It is well-documented that (bio)chemical reaction capacity of raw potato starch depends on crystallinity, morphology and other chemical and physical properties of starch granules, and these properties are closely related to gene functions. Preparative yield, amylose/amylopectin content, and phosphorylation of potato tuber starch are starch-related traits studied at the genetic level. In this paper, we perform a genome-wide association study using a 22K SNP potato array to identify for the first time genomic regions associated with starch granule morphology and to increase number of known genome loci associated with potato starch yield.

Methods

A set of 90 potato (Solanum tuberosum L.) varieties from the ICG "GenAgro" collection (Novosibirsk, Russia) was har
