[Analysis of genetic diversity of wheat using genetic resources information system GRIS].
The possibilities of using the Genetic Resources Information and Analysis System (GRIS) 3.2, a database and software package, in studies of various aspects of genetic diversity in wheat are demonstrated. A model of genetic diversity was analyzed; diversity levels were estimated in wheat from various regions at different times. The genetic basis of Russian winter and spring common wheat cultivars was investigated. Transmission of powdery mildew resistance genes was traced in cultivars with identified Pm genes. For some genes, patterns of geographical distribution were characterized. Description of GRIS 3.2 is given: the package consists of a database on the global gene pool of wheat and software on genealogical and statistic analyses of genetic diversity.
