| مستخلص: | Maize dwarf mosaic (MDM) is a widespread viral disease of maize (Zea maysL.) in the southern U.S. Corn Belt. An understanding of the genetics for resistance to maize dwarf mosaic virus (MDMV) will provide a rational basis for effective selection. Our objective wast o determine the genetic basis of resistance in inbred Pa405 to Strains A, B, D, E, and F of MDMV by examining the association between host symptomr esponses, and chromosomal translocation and morphologicaol r molecularm arkers. Twenty‐six translocation markers and the morphological marker yl were incorporated into inbred MI4. Linkage relationships with molecular markersw ere determinedb y restriction fragment length polymorphism (RFLP) analysis, using molecular markers UMC85, BNL6.29, UMC59a,n d UMC21T. he three approachesa ll indicated a gene or genes on either the short arm or the proximal region of the long arm( proximal to YI) of Chromosom6e i n inbred Pa405 controlling resistance to all five strains of MDMV. |
