E.  aMapping of a locus controlling resistance to Albugo candida in Brassica napus using molecular markers.h[electronic resource]  c1995  ap.218-220  aWhite rust, caused by Albugo candida, is an important disease of crucifers, vegetables, and oilseeds in many countries. A backcross population, BCP2, as well as F1-derived doubled-haploid (DH) and F2 populations obtained from the same single F1 plant, produced from the cultivar Major × Stellar, were used to study the genetic control of resistance to white rust in Brassica napus. The control of resistance to white rust in this cross was attributed to a dominant allele at a single locus, designated ACA1. Other loci may be involved in the control of the intensity of sporulation of the fungus in the plant. The ACA1 locus was mapped with respect to restriction fragment length polymorphism (RFLP) loci in the F1DH population. Linkage between the ACA1 locus and nine RFLP loci was observed on linkage group 9 of a B. napus RFLP linkage map.  aAlbugo candida  aBrassica Napus  aMarcadores moleculares  aMolecular markers1 aWILLIAMS, P.
