EFFECT OF ENDOGENOUS AND EXOGENOUS FACTORS ON PRODUCTIVITY, CONTENT OF PROTEIN AND GLUTEN IN GRAIN OF PRESENT WINTER WHEAT VARIETIES

Abstract

The article gives the results of the productivity analysis and biochemical analysis of 67 winter wheat varieties from 11 breeding centers of Russia, which participated in ecologic trials in Shatilov ATS in 2012-2013. It was shown influence of genotype and growing conditions on productivity and grain quality of winter wheat. These were found the most promising varieties for the Orlov region, which produced high yields of qualitative grain. We concluded that the varieties are of great interest for production as at a minimal increase of cultivation cost they produce yields in twofold per unit of land in comparison with previous zoned varieties. At the same time the article highlighted, that weather influence on productivity and winter wheat grain quality still remained rather strong. So it was suggested to reduce this negative effect by differentiation both varieties and agro technical methods. In cultivation of winter wheat variety ‘Moskovskyay 39’ in Orlov region it is recommended a mineral fertilizing (NPK17), a top-dressing with nitrogen (N68) in the spring tillering phase combined with a non-root fertilizing with carbamide (calurea) (N46) in a earing phase, which will give yields of 5,5-6,0 t/ha with gluten content of more than 27%.
