The purpose – to develop ways of increasing breeding efficiency using modern information technologies. Methods – field, laboratory, information technologies, statistical. Results: сreated three main working collection of varietal diversity and number of working collections of soft and hard winter wheat for research and practical purposes of selection. The possibility of using low-cost , mass- available technology (office scanners , compact digital cameras , smart cameras ) to provide suitable for the analysis of digital images of grain, ear , and other objects that characterize the collection and breeding material. Metrological evaluation of the data analysis of these images indicates the prospects of using mass gadgets in research. In terms of the compact wide-row planting of the collection and hybrid material with a soft winter wheat on a "spike-number" shows the hereditary nature of the estimates made in the years of research for the size of signs, shapes, colors, corn, grain hardness (hardness), plant height, heading date. Significant correlations of these estimates with the characteristics obtained by continuous ( pushed plot ) sowing . The research degree of similarity " trees " constructed by molecular markers and morphological characters . We summarize the results of many years of joint research with the Department of Genomics and Biotechnology for the use of molecular markers for genetic evaluation and description of varieties of GIS , a statistically significant association of allelic composition of SSR - markers with a number of significant signs of breeding The algorithms detect the spatial variation of fertility research field , optimizing layouts areas in order to maximize the effect of leveling found " wavy " (wavelets) irregularities in the results of variety trials . On a material of a network of demonstration crops held to find the most efficient algorithms for the study of environmental data with the variety trials data matrices varying degrees of fullness . Together with scientists from the former plant introduction laboratory developed test approaches to data analysis introduced forms , the structure of which is complicated by the presence of variations in the components caused by regional specificity . Create a similar test analysis scheme , which will be the basis for the standard sequence . The scheme provides a consistent study of the variations caused by regional characteristics, revealing the hidden structures by the use of means of multivariate statistics (breakdown of the total variation on the " main components ") and cluster analysis . The scheme is tested on the collections of winter wheat and spring barley. Introduction: it was created and constantly enhanced the collection of adapted standard varieties for using in methodical researches.
