Abstract: Research was carried out during 2014-2017 at the Experimental Station of Aleksandras Stulginskis University on Calc(ar)i-Endohypogleyic Luvisoi (LVg-n-w-cc). The effect of exogenous amino acids on cold tolerance of linear cultivar "Cult" of winter oilseed rape (Brassica napits L. spp. oleifera biennis Metzg.) was studied. In autumn the plants were sprayed with I -proline and L-glutamic acid one or two times. Biometric parameters of winter oilseed rape prepared for wintering, amount of endogenous proline and over-wintering of plants were evaluated. It was determined that exogenous L-proline and I.-glutamic acid stimulated the growth of green mass of the winter rape surface, accumulation of dry matter and increase of the root neck diameter in the autumn period. The investigated concentrations of L-proline and L-glutamie acid stimulated more intensive synthesis of endogenous proline in winter oilseed rape plants during the preparation for wintering. The highest percentage of over-wintering has been determined in variants where plants in the autumn were sprayed two times with 30 mM I -1 L-proline or 1.5 M l-l L-glutamic acid
