“…Mutagenic effects of chemicals have been assessed by both analysis of chromosomal aberrations (Rakhmatullina and Sanamyan, 2007) and investigation plant development and grows at first generation under field conditions. Chromosomal abnormalities in irradiated mitotic cells range from breaks, through exchanges, laggards and anaphase bridges, dicentric and centric ring formations, terminal fragments with telomeric signal at only one end and interstitial fragments that appear as double minutes without any telomeric signals (Rakhmatullina and Sanamyan, 2007).…”

The strategy of investigation combined the identification of genotypes carrying specific low-sensitive to mutagen factor using cytological and morphometrical analyzes screening of mutagen treated wheat populations with the approach of comparing different varieties by breeding methods to reveal its connections and differences, specific sensitive to mutagens effects on cell and plant level. The main purposes of investigations in this area were identification more suitable varieties for planting on mutagen-polluted area or as an object for mutation breeding.Here we report cytogenetic, plant growth and development characteristics of mutation induction variability of the new wheat varieties and some relationships between means of plants grows and developments, morphometrical parameters, cytogenetic characteristics and different concentrations and types of mutagens at first generation after mutagen treatment.

“…A relation amid clastogenic adaptation shown in descending of chromatid type of changes, micronuclei and changes in number of chromosomes in cells, and the clastogenic effect has been appeared (Grant, Owens, 2001;Bignold, 2005). Influence of different types of chemical mutagens or any type ionizing radiation according to this method can be analyzed by summarized number and kinds of chromosomal damages (Rakhmatullina, 2007). Both structural and numerical aberrations occur spontaneously due to intraneous and extraneous factors and appear in terms of last mitotic cell division phases (Nikolova et al, 2015).…”

“…Changes in chromosome number and structure in mitotic cells is initiated after mutagen action. Chromosomal changes rank from breaks, through exchanges, laggards and anaphase bridges, dicentric and centric ring formations, terminal fragments with telomeric signal at only one end and interstitial fragments that appear as double minutes without any telomeric signals changes in irradiated mitotic cells (Bolzaґn, Bianchi, 2006;Rakhmatullina, 2007). Joining with gene mutations, chromosomal aberrations in the form of different structure rebuilding (deletions, inversions, translocations, etc) were generates (Shu et al, 2011).…”

In the article we report about our investigation of cytogenetic parameters in chromosomal complex of the new Ukrainian winter wheat varieties and some relations amid value of cytological indexes and different concentrations of DMS (dimethylsulfate). We used the anaphases method for the investigation of chromosomal rearrangements and determination the mutagen action on plants and identification the nature of mutagen. We studied combined the sensitivity of genotype by the cytological analysis of mutagen treated population of wheat and revealed the reaction of different varieties depending upon the way of its origin. This was done for determining its connections and differences on cytogenetics level together with specificity of mutagen action on cell level. Dry seeds of seven varieties and one line of winter wheat were subjected to DMS in 0.0125, 0.025, and 0.05 % concentrations, which are the most useful for winter wheat in terms of genetic investigation programs. We investigated the rates and spectra of chromosomal aberrations in winter wheat (primary roots of tips cells) during the mitosis. We identified the following types of chromosomal rearrangements: chromatid and chromosome bridges, single and double fragments, micronuclei, and lagging chromosomes. Investigation of DMS action confirmed reliability of fragments-bridges ratio (prevalence of fragments under the bridges for chemical mutagens and vice versa for physical mutagens) for the mutagen nature identification.

SUMMARYThe strategy of investigation combined the effects of mutation depression evident at first generation on cell and plant level and peculiarities of recurrent mutagen action. The main purposes of investigations in this area were determination genotype-mutagen interaction for modern Ukrainian winter wheat varieties, identify sensitive of genotypes for DMS (dimethylsulfate) genotypes and evolution repeat action of mutagen as a method in difference alteration on firs step of mutation breeding program, which limited next stages by quantity of material for breeding. Here we report cytogenetic, plant growth and development characteristics of mutation induction variability of the new wheat varieties and some relationships between means of plants grows and developments, morphometrical parameters, cytogenetic characteristics and different concentrations and types of mutagens at first generation after DMS action.
