摘要

One hundred and sixty one genomic STMS markers were tested from four different Brassica species (Brassica napus L., Brassica nigra (L.) Koch, Brassica rapa L. and Brassica oleracea L.) for cross-transferability to eleven different species of Brassica and allied genera. In total, 70 (43.5%) STMS markers showed cross-transferability to at least one of the eleven species which were considered for the study and it revealed a significant effect of taxonomic group on the proportion of markers amplified. Out of the 70 cross-transferable STMS markers, 32 (45.7%) markers were polymorphic and distinguished the studied taxa. The ‘B’ genome derived STMS markers showed lower level of cross-transferability as compared to those derived from ‘A’ and ‘C’ genomes of Brassica species. The cross-transferable STMS markers were applied to characterize the genetic variability and to evaluate the genetic relationships among the species using un- weighted pair group method average (UPGMA) analysis. The results indicated a high level of congruence with earlier reports and are in agreement with their recognized taxonomy.
