GENETIC-MAPPING OF NEW MORPHOLOGICAL, ISOZYME AND RAPD MARKERS IN VICIA-FABA L USING TRISOMICS

Thirteen F-2 families of faba bean (Vicia faba L.), descended from pla nts trisomic for chromosomes 3, 4, 5 and 6, have been analyzed for mor phological, isozyme and RAPD markers. This allowed the establishment o f linkage relationships among these markers as well as the assignment of some markers and/or linkage groups to their respective chromosomes. The linkage analysis of partially overlapping sets of informative gen etic markers for the data pooled from 13 F-2 families has revealed 48 linkage groups, six of which have been precisely assigned to specific chromosomes. A statistical procedure to analyze the data of joint segr egation analysis in families derived from trisomic plants has been dev eloped.
