Abstract: The aim of our investigation was to determine the effect of sowing time of winter oilseed rape en autumn rosette chemical composition and over-wintering. The experiment carried out in the Experimental Station of Lithuanian University of Agriculture in 2009-2010. Chemical composition of rossete of winter rape sown at different time influenced crop over-wintering - significant correlation between this indicators was established. The stronger influence of the winter rape rosette composition on over-wintering was established in rape of linear cultivar 'Sunday' than in rape of hybrid cultivar 'Kronos'.Winter rape of hybrid cultivar over-wintered better - 39, 2-77,0%, winter rape of linear cultivar - 12,8-54,0%. Winter rape sown on 30 August - 5 September best over-wintered. They acumulated 15,23-18,14% of dry matter, 5,03-5,69% of total sugar, N and K ratio was 1,64-1,72 in leaves, and in apical bud - 18,43-19,68% of dry matter, 6,00-8,49% of total sugar, N and K ratio was 1,58-1,69. Winter rape of hybrid cultivar sown at later dates prepared for over-wintering more intensively. Winter rape of both cultivars sown at the latest date not over-wintered
