ANALYSIS OF PRODUCTIVITY ELEMENTS IN WINTER TRITICALE

Abstract

Results are given from studies of winter triticale collection samples during the period of 2010-2013 at the Siberian Research Institute of Plant Production and Breeding. There were selected the samples with a number of economic traits. Of particular interest are those that have an index of productivity elements exceeding three-fold standard deviation (X + 3s). Of 120 winter triticale samples studied, 16 had high productivity, 8 - the largest number of spikelets per ear, 13 - high grain content, 17 - high ear productivity, 14 - high thousand-kernel weight. Seven triticale varieties characterized by a complex of economic traits have been selected. The winter triticale collection forms identified can be used in breeding programs for developing high-productive varieties with high yield potential to be cultivated under conditions of Western Siberia.
