Chickpea During the last twenty years, breeding of cool grain legume crops has been carried out at the DAI in General Toshevo (Mihov et al., 2002). Two chickpea cultivars (Obraztsov chiflik and Stepnoj) with contrasting features were treated either with 60Co gamma rays or EMS or both (Table 1; Atanasova et al., 2004a; 2004b). The results showed that there is a significant genotypic effect on the frequency of induced mutations. As a result of crossing with a mutant line, one cultivar of the crop bitter vetch (Borina) and pea vine (Strandja) were developed and registered. In 2001, new genotypes of plant species chickpea and vetch were presented for testing and registration. Seed production of the main cultivars was organized to meet the demands of the producers in the country. Mutant lines with different morphological characters of great interest to breeding were developed, which enriched the germplasm of chickpea. Some of them are directly used in breeding new cultivars and others are used as parents in cross-breeding programmes.
