PHYSICAL AND CHEMICAL PROPERTIES OF GRAIN OF WINTER RYE DIPLOID BREEDS GROWN IN TOMSK REGION SUB-TAIGA ZONE

Abstract

The paper addresses the physical and chemical characteristics of two breeds of diploid winter rye: Petrovna and Narymchanka. Different groups of seeds were identified: average with respect to population, green grain and red grain. The research revealed the differences among the studied groups in the weight of 1000 grains of 24.3 – 31.4 g. In 2012, the green grain of Narymchanka breed was characterized with the weight of 1000 grains above the average: 31.4 g. On the contrary, the content of starch was highest (60.2 %) in the red grains of 2011 Narymchanka breed. The content of protein dependes on the temperature factor and varies between 5.32 – 16.07 %.
