In the breeding nurseries and also in the competitive variety trial, the initial material of the meadow clover (Trifolium pratense L.) of the double-cut diploid was tested. The aim of the research is to select the most economically useful cultivars and create a new early-maturing variety. In the selection was used free pollination method, free and limited pollination method, mass and individual selection, polycross. Research was done from 2009 to 2014 in a laboratory and breeding crop rotation in the Smolensk State Agricultural Experimental Station named after A.N. Engelhardt. Methods of research are widespread. Clover was grown on sod-medium podzolic light loamy soil in contrasting weather conditions of the growing season. Methods of cultivation were typical for the Smolensk region. From 2011 to 2014, the best selective number was the S-434. It is early-maturing (period from spring growth till first cutting is shorter than that of the standard for 5…7 days; till seeds ripening – for 8…10 days), has high winter hardiness (97,4%, or +5,5% to standard), green mass yield for two cuttings – 69,8 t/ha (+25,5% to standard), forage productivity of 17,3 t/ha of air-dry matter (+26,3% to standard), seed yield of 330 kg/ha (+17,9% to standard). The crude protein content was 17,3% of dry matter (more than in the control by 1,3%). Growing of selective number S-434 on seeds is 8% more profitable. Selective number S-434 is named Pochinkovets. In 2018 he was registered in the State Register of Selection Achievements.
