Russian. The article presents the results of studying the effect of a number of quantitative traits on rice productivity. It is necessary to create new varieties with desirable traits in order to increase rice productivity. The aim of the research is to study influence of elements of yield structure on productivity of control farm rice. As a result of research, analysis of variation of trait values in rice samples was carried out and regularities of their influence on productivity were established. The highest productivity 7,5-8,0 t/ha is formed at presence of optimum values of traits: height – 90-95 cm, length of panicles – 16-17 cm, number of ears on panicle – 110-120 units, weight of 1000 grains – 32-36 g., number of productive stems on 1 m2 – 300-350 pieces. The obtained optimum values can be used in the formation of the variety model.
