The paper presents results from three-year (2008-2010) strict field experiments carried out at The Experimental Ecological Farm Chwałowice, Agricultural Advisory Center in Brwinów (branch in Radom). The experimental field was established on brown soil with granulometric composition of moderate soil close to heavy. The soil was classified as included into defective wheat complex, class IV b. Twelve varieties of spring wheat were evaluated during the experiments. Wheat grain quality expressed as 1000-grain weight is highly valued by consumers. Within studied set of spring wheat varieties, Hera, Korynta, and Nawra cv. were distinguished by high 1000-grain weight. Under conditions of organic farming, these varieties can be regarded as intensive ones, that after weed control using mechanical methods, can also produce grain yields with high percentage of quality grain. Cytra cv. proved to be interesting, because it produced significantly the largest number of grains per 10 ears; although the grain was of the highest weight, its size was medium.
