摘要： The detrimental effects of drought on crop production are strongly influenced by interactions with other biotic and abiotic stresses, including Fusarium crown rot (FCR), a disease known to cause severe yield loss in crops experiencing drought after anthesis. This study aimed to identify loci that simultaneously confer drought tolerance and FCR resistance using a recombinant inbred line (RIL) population. The population derived from a cross between cultivated barley (Hordeum vulgare L.) and wild barley (Hordeum spontaneum C. Koch.), was evaluated under drought-stressed and non-drought-stressed conditions. Three loci conferring drought tolerance were identified on chromosome arms 2HL, 4HL and 5HS. Of these, the 2HL locus had the largest effect, influencing leaf wilting, leaf senescence and shoot dry weight, and importantly, also conferred FCR resistance. The RIL population was exposure to FCR infection and drought stress in glasshouse and controlled environment facility, respectively. Genotyping-by-sequencing (GBS) was used to develop a high-density genetic map, which facilitated QTL identification through linkage analysis. Significant correlations were observed among the assessed traits and previously collected agronomic traits. Candidate genes at the 2HL locus were identified based on its location and sequence variations between parental genotypes. This study represents the first identification of such a locus conferring both drought tolerance and FCR resistance, which may open new avenues for leveraging existing drought tolerant genes in enhancing FCR resistance by targeting pathways associated with water stress adaptation.
