Abstract

Abstract: In this research conducted in the Department of Field Crops, Agricultural Faculty, Namık Kemal University, the effect of six different gamma ray doses on plant growth in M1 and M2 generations derived from two durum wheat cultivars was investigated. When mutants and control genotypes in M2 generation were investigated for seven characters, a considerable number of mutants having the desired characteristics were obtained. The application of 200 gray dose resulted in significantly short genotypes among selected mutant genotypes. After 300 gray dose applications, suitable genotypes were obtained in terms of plant height, seed yield per main spike, the number of seeds per spike, harvesting index and spike length. In addition, mutagen application increased number of tillers per plant. For obtained protein band design using the SDS-PAGE method in the Standard and mutant durum wheat genotypes were observed different in 300, 400 and 500 gray mutagen doses
