The article obtained hybrid seeds of rice using local and foreign varieties and samples for resistance to diseases and pests, shedding and lodging in field conditions, depending on biological and valuable economic characteristics, and determined the salt tolerance of the ridges on the basis of marker proteins. However, in the primary source nursery, the ridges were studied on valuable economic indicators and 10 ridges as early maturing ridges and 9 ridges as middle and late ridges were selected for use in future research as generations.
