Fine-mapping of <i>PmHHM</i>, a broad-spectrum allele from a wheat landrace conferring both seedling and adult resistance to powdery mildew.

ABSTRACT:

Introduction

Common wheat is a leading global food crop that impacts food security. Wheat powdery mildew (PM), caused by Blumeria graminis f. sp. tritici (Bgt), poses a significant threat to grain yield and flour quality. The identification and utilization of broad-spectrum resistance genes against PM are essential for effective disease control.

Methods

The resistance spectrum test during the seedling stage and the identification of resistance during the adult stage were conducted to evaluate the wheat landrace Honghuamai (HHM). Five segregating populations were investigated to assess the inheritance of PM resistance in HHM. To map its PM resitance gene, bulked segregant analysis, molecular mapping and comparative genomic analysis were also used in the p
