Breeding method for yield varieties of rice

The paper describes a method for creating new and increasing the yield of existing varieties based on the analysis of the variability of the elements of the structure of the yield of rice varieties under the influence of environmental conditions. Seeding rates are used as a source of variability. The following are analyzed: field germination of seeds, survival of plants before harvesting, total bushiness of plants, realization of total bushiness, graininess of panicles, fertility of spikelets, weight of 1000 grains. Based on the analysis, through the connections of conjugated elements, the optimal values of the elements of the crop structure are determined, at which it takes the maximum value. Based on a set of optimal values, a theoretical model of the studied rice variety is being developed. Then, according to the panicles selected in the variety, single-row plots are sown and for further reproduction, rows with the parameters of the crop structure elements set by the variety model are selected, which makes it possible to increase the yield of the Mavr rice variety by 39.18 centners / ha or 45.61%.
Keywords: Rice, breeding method, yield.
