Over 2003-2005 an experiment aimed at evaluating yielding and quality characters of Korweta cultivar winter wheat. The cultivar yielded highest after pea, lower – by 10.1-10.7% – after potato and single sowing after itself, whereas the lowest – (by 19.3-24.9%) after 2- and 3-time sowing after itself. Similarly winter forecrops differentiated the quality characters of the grain. The highest amount of total protein and wet gluten and the Zeleny sedimentation value were found after potato, wheat sown 3 times after itself and after pea. The falling number, test weight of the grain and grain uniformity were differentiated only by weather conditions over the research years analyzed. The grain yield was negatively correlated with the content of protein and gluten in the grain and positively – with the test weight and grain uniformity. The total protein content was positively correlated with the content of gluten and the Zeleny sedimentation value.
