Breeding rice with a vertical position of the sheet in the space to increase the productivity of modern varieties as one of the important areas

As before, to increase the productivity of rice plays an important creation of new varieties. Creation of plants with erect position of leaves allows to compact sowings and to increase the productivity of cenosis. There were studied the rice samples with erect leaves and large grain as an initial material for selection on increased productivity. In order to reduce the complexity and improve the quality of the selection process in the early stages, it is necessary to leave a visual estimation of some parameters of rice plants. Transitioning to the use of mathematical formulas to determine the coefficients reflecting the maximum number of indicators to improve or automate the selection. As one of these formulas and calculation methods we offer OMS. As a result, the calculation of OMS is possible to estimate the plant in terms of productivity. The indicator OMS shows how many units of square plates flag and podflagovogo leaves working on the formation of units of the grain mass, which characterizes the efficiency of the studied plants. As the most productive vertikalnolistnye samples allocated M 1 and M 2, OMS value of y which is at the level of the standard varieties and varieties Rapan, Pavlovsky.
