QTL detection, validation, candidate genes and KASP markers for pre-harvest sprouting tolerance in white grained common wheat.

ABSTRACT:

Background

Pre-harvest sprouting (PHS) in common wheat refers to the premature germination of grains on the spike under high humid conditions. This phenomenon increase alpha-amylase activity and degrade starch, resulting in reduced falling number (FN) and compromised milling and baking quality. The genetic control of PHS is complex and polygenic, presenting a significant challenge but also offering opportunities for trait improvement through targeted breeding.

Results

A doubled haploid (DH) population comprising 386 lines, derived from a cross between two white-grained spring wheat genotypes SC8021-V2 (PHS-tolerant) and AC Karma (moderately susceptible to PHS), were evaluated for sprouting score (SS) and FN traits across two locations over two crop seasons in India.
