Abstract

Twenty grasspea forms obtained by mutagenesis from Polish cultivars Derek and Krab were evaluated for seven qualitative traits in field trials performed in the years 2002 and 2003. Two-factorial analysis of variance including objects and years was done. The interactions between these factors were significant for all the traits at the level α = 0.001. In most cases the values characterizing the traits in mutants were lower than those in the initial cultivars. The differences were marked in both years of the study, but they were largely pronounced in 2003, presumably because of the additional stress caused by the long-lasting drought. The environmental conditions of the year 2003 made possible to assess a reaction of mutants to the drought stress, and to select the most tolerant genotypes.
