Journal ArticleDOI
Aligning male and female linkage maps of apple (Malus pumila Mill.) using multi-allelic markers
Chris Maliepaard,F. H. Alston,G. van Arkel,L.M. Brown,E. Chevreau,Frank Dunemann,Kate Evans,Susan E. Gardiner,Parry Guilford,A.W. van Heusden,J. Janse,François Laurens,James R. Lynn,A.G. Manganaris,A.P.M. den Nijs,N. Periam,Erik H. A. Rikkerink,P. Roche,C. D. Ryder,Silviero Sansavini,H. Schmidt,Stefano Tartarini,J.J. Verhaegh,M. Vrielink-van Ginkel,Graham J.W. King +24 more
TL;DR: The high marker density and large number of mapped codominant RFLPs and some microsatellite markers make this map an ideal reference map for use in other progenies also and a valuable tool for the mapping of quantitative trait loci.
Journal ArticleDOI
The ‘European Apple Genome Mapping Project’-developing a strategy for mapping genes coding for agronomic characters in tree species
Graham J.W. King,F. H. Alston,I. Battle,E. Chevreau,Cesare Gessler,J. Janse,P. Lindhout,A.G. Manganaris,Silviero Sansavini,H. Schmidt,K. Tobutt +10 more
TL;DR: A recently initiated collaborative project involving apple breeders in seven European countries to improve the European apple crop by molecular-aided breeding to increase efficency and reduce the time-scale in breeding for resistance, tree habit and fruit quality is described.
Journal ArticleDOI
Multiple field and glasshouse assessments increase the reliability of linkage mapping of the Vf source of scab resistance in apple
Graham J.W. King,F. H. Alston,L.M. Brown,E. Chevreau,Kate Evans,Frank Dunemann,J. Janse,François Laurens,James R. Lynn,Chris Maliepaard,A.G. Manganaris,P. Roche,H. Schmidt,Stefano Tartarini,J.J. Verhaegh,R. Vrielink +15 more
TL;DR: The results obtained for the consensus classification of resistance to scab for the population may suggest the presence of virulent inocula at some sites, which could overcome the Vf gene for resistance.
Book ChapterDOI
Early selection for partial resistance to powdery mildew, Podosphaera leucotricha (Ell. et Ev.) Salm. in apple progenies
TL;DR: Nursery selection for partial mildew resistance can be effective, but the efficiency varies between populations, and individual correlations of resistance between nursery and orchard also varied per progeny.
Journal ArticleDOI
