Abstract

A total of 266 Martonvásár (Mv) wheat (Triticum aestivum L.) accessions, including varieties and advanced lines, were examined using the "Perfect" molecular markers to detect the Rht-B1b (formerly Rht1) and Rht-D1b (formerly Rht2) semi-dwarfing genes. The gene Rht-B1b was detected in a total of 221 (83.5%) accessions. The Rht-D1b allele was found in fewer accessions. Overall 24 genotypes (9%) contained this allele. The analysis of the development date of the genotypes revealed that the introduction of the dwarfing genes into Martonvásár breeding programmes started in the early 1970s, and they were widely utilized from the 1980s. The Rht-B1b allele was the main source for reducing plant height, while the Rht-D1b allele played only a minor role in the Martonvásár breeding programme. Characterizing accessions using various molecular markers allows us to create a database offering relevant marker information about genotypes. Such a database could be very helpful for selection, allowing breeders to include varieties giving positive results in specific breeding programmes.
