The products of around 41 loci could be distinguished in these systems 13 of which displayed polymorphism. The genetics of 7 isozyme loci have been studied using 8 fullsib families acp1 Iap1 sdh1 and mdh1 functioned as monomers and got1 idh1 and me1 were active as dimers. Two other isozymes pgm1 and got2 appeared to have simple inheritance but it was not possible to verify this. Joint segregation of 13 locus pairs showed linkage between Iap1 and got1 r and between Iap1 and me1 r . Idh1 sdh1 acp1 and mdh1 are not linked to these loci. No linkage has been detected between acp1 and mdh1. Prunes avium L. wild cherry Isozyme variability inheritance linkage Résumé - Marqueurs génétiques pour Prunus avium L déterminisme génétique et groupes de liaisons entre loci enzymatiques. L espece Prunus avium comprend les cerisiers variétés améliorées peer la production de freits et les merisiers arbres forestiers de qualité ser lesqeels portent aessi des programmes d amelioration. II serait utile pour ces programmes de disposer de marqueurs génétiques pour les identifications clonales et interspecifiques analyse de la variabilité naturelie et du système de reproduction et le controls des produits de croisements dirigés. Comme peu de marqueurs génétiques avaient été étudiés Chez p avium nos efforts ont porte sur la recherche et la caractérisation de loci enzymatiques. Le polymorphisme .
