An assortment of ten amphidiploids and twenty-five mutant/recombinant new genotypes plus their parental forms of winter wheat were studied for generating information on genetic variability of some quantitative characteristics. Field experiments were conducted at Caracal Agricultural Research and Development Station during 2015-2018. The data wer recorded after harvest and refers to plants height, number of fertile tillers, spike length, number of spikelets/spike, number of grains/spike, grains weight/spike, thousand grains weight and yield. Analysis of variance revealed significant differences among the category of genotypes for all the characters due mostly to the influence of the climatic conditions of the region. The correlations established between the traits indicate same type of relationships, not very different depending on the method of obtaining of the genotypes and these could help researchers in the process of selection of genotypes with desired traits. For this experiment, it can conclude that some of the experimented material can be used in further breeding programmes. In the category of amphidiploid genotypes higher amplitude of variation was identified especially for yield while for the mutant/recombinant genotypes, characters variability was smaller and correlations were stronger. Also, for this category, values registered for the analised traits were closer to parental forms.
