Summary. Winter rye is the most adapted crop to conditions of the northern agriculture of Russia. A variety is an essential factor of obtaining of the maximal and stable grain productivity. Falenskaya 4 variety of winter rye is one of the widespread and important rye varieties in Russia. Its average productivity under conditions of Kirov (2000-2013) was 5.21 t/ha. The regenerative ability of plants was about 96% at annual 100% defeat by snow mold. The winter hardiness was 8.6 points, lodging resistance–7.7 points. During the studying of the variety against different soil backgrounds (usual and provocative ones on acidity and aluminum content) at Falenskaya breeding station (Kirov region, Russia) the average productivity under conditions of an edaphic stress was 3.04 t/ha (61.2% of the usual background). This is considerable higher than for the standard variety Kirovskaya 89. Under neutral conditions of the soil background the yield of the Kirovskaya 89 variety reached 4.14 t/ha; and the edaphic stress led to its decrease to 1.8 t/ha, or to 43.5% of the usual background. The yield shortage occurs mainly due to the decrease in the regenerative ability of plants by 39.8% and in productive tilling capacity by 26.7%. Falenskaya 4 belongs to leaders among winter rye on the occupied areas in Russia because of its high adaptability and edaphic resistance. It is possible to recommend the variety as a source of aluminum- and acid-resistance in winter rye breeding. In 2013-2014 the Falenskaya 4 variety passed tests in the PRC (Baicheng, China). Possibility of its cultivation on saline soils at the deficiency of moisture was revealed.
Keywords: winter rye, variety, productivity, winter hardiness, regeneration, soil acidity, saline soils, aluminum ions, resistance.
