06.00.00 Agricultural sciences
DescriptionThe introgression of race-specific blast resistance genes Pi-ta, Pi-b, Pi-z into genotype of Russian rice variety has been performed by backcross method with marker control of donor alleles. Plants that demonstrated maximal similarity with recurrent parental form, the short vegetation period and abundant panicle fertility have been picked up from BC3-population. Marker analysis of developed population revealed the samples carrying introduced target genes in homozygote state

Description
This article is devoted to the research of influence of genetic algorithm key parameters of genetic schemes method on efficiency of optimum decisions search in expert systems. The following parameters of genetic algorithm are considered: number of population, length of binary codes, the mechanism of parental pairs selection, the choice of the reproduction scheme

MOLECULAR MARKERS AND HOW TO USE THEM IN BREEDING AND GENETIC RESEARCHERS
06.00.00 Agricultural sciences
DescriptionProgress of molecular genetic developed different types of DNA-markers, which are founded on analysis of DNA-polymorphism. Using of these markers has hanged methods of genetic diversity estimation as well as plant cultivars passportisation and classification

Description
As result of evaluation 24 common wheat introgression lines with genetic material Agropyron glaucum the considerable variability of resistance to leaf rust was revealed. Genetic control of leaf rust in introgression lines 60 and 109 was studied using hybridological analysis. Both lines contained single dominant genes differed from each other and from the known effective Lr19 and Lr24. The investigated lines with genetic material Agropyron glaucum are valuable donors of the genes for leaf rust resistance
