INFLUENCE OF SOIL-AND-CLIMATIC CONDITIONS ON WINTER RYE PRODUCTIVITY, WINTER HARD
Main task of winter rye breeding is creation of varieties adaptive to different soil-and-climatic conditions, which provide high and stable grain yields. Under conditions of Kirov region 11 zoned and perspective varieties were studied. Investigation was conducted at two soil backgrounds (normal background and natural provocative by acidity and content of aluminum ions) for reveal perspective genotypes with lowest degree of depression on winter hardiness and productivity. On a basis of three-year study variety Kiprez could be recognized as perspective, tolerant to aluminum-acid stress.
