摘要：

The genetic variability and collection structure of the wheat leaf rust fungus Puccinia recondita collected from four agro-ecological areas of Morocco, Abda-doukala, Chaouia-Tadla, Gharb and Tangerois were investigated by amplified fragment length polymorphism (AFLP) markers. A set of five AFLP primers combinations which generated 253 polymorphic loci were used. Hierarchical partitioning revealed that bread wheat collections of Puccinia recondita form a single collection. No significant variation was observed between durum wheat collections of Puccinia recondita; they maintained most of the genetic variability within rather among collections. The distribution pattern of genetic variation of Puccinia recondita collections seems to be the result of high gene flow and the mixed reproduction system.
