ABSTRACT Molecular tools have not identified markers for host‐plant resistance to fall armyworm [ Spodoptera frugiperda (J. E. Smith)], one of the most damaging insect pests in turfgrasses southeastern United States. Available quantitative trait loci (QTL) maize ( Zea mays L.) further been assessed utility as comparative across related taxa. This study reports a linkage map region conferring major control zoysiagrass Zoysia spp.). One genomic simple sequence repeat (ZgAg136) and amplified fragment length polymorphism (Zgaw216) were linked flanked locus Zfawr1 ) by 6.3 8.8 cM, respectively. These offer immediate value toward marker‐assisted selection potentially additional important crops. Nonsynteny between was indicated absence 38 candidate from QTL regions . As major‐effect putative novel source gene(s), is promising target investigation.
