A genetic map of citrus based on the segregation of isozymes and RFLPs in an intergeneric cross

Abstract

Isozymes and restriction fragment length polymorphisms were used as markers in the construction of a genetic map of the citrus nuclear genome. The map was based on the segregation of 8 isozyme, 1 protein, and 37 RFLP loci in 60 progeny of a cross of two intergeneric hybrids, 'Sacaton' citrumelo (Citrus paradisi Macf. x Poncirus trifoliata (L.) Raf.) and 'Troyer' citrange (C. sinensis (L.) Osbeck x P. trifoliata), often used as rootstocks. The map contains 38 of 46 studied loci distributed on ten linkage groups. A genome size of 1,700 cM was estimated from partial linkage data. Approximately 35% of the genome should be within 10 cM and 58% within 20 cM of the mapped markers. Eight loci in three linkage groups and 1 unlinked locus deviated significantly from Mendelian segregation.
