“…The value of high genetic diversity in the number of productive tillers during the M2 generation allows selection for that generation. M. Shabani et al (2022), also reported gamma-ray irradiation led to an increase in genetic diversity, resulting in higher number of productive tillers and yields per wheat plant. The greatest amount of productive tillers was in Bantul 100 Gy is 28 with code M2-BT1-4-8, while Boyolali 100 Gy had the greatest amount of productive tillers 23 at M2-BY1-1-11 (Table 2).…”

“…Identification of the key components of cytogenetic variability makes it possible to significantly simplify the future selection of the required doses and concentrations of the mutagenic factor (Amri-Tiliouine et al, 2018). At the same time, they are guided primarily by such factors as the achievement by certain values of the corresponding milestones with the maximization of activity or a plateau in activity for some indicators (Shabani et al, 2022). For chemical supermutagens, such variants were repeatedly considered signs of the induction of fragments and double fragments in the spectrum of chromosomal aberrations, the general frequency of rearrangements (Beyaz et al, 2016).…”

The study of cytogenetic parameters of the activity of new mutagenic factors aims to reliably establish the possibilities of these factors in terms of variability depending on the subject of mutagenic action, the optimal use of certain factor sizes, the combination of the selected protocol with optimization of the yield of mutant forms in the future. Seeds of eight varieties of winter wheat (Balaton, Borovytsia, Zeleny Gai, Zoloto Ukrainy, Kalancha, Niva Odeska, Polyanka, Pochayna) were treated by SA (sodium azide) at concentrations of 0.010%, 0.025%, 0.05%, 0.10%. They were soaked in water solution for 24 hours. Cytogenetic activity was evaluated by pollen sterility, evaluation of general rates and indicators of spectra of chromosomal abnormalities at medium phases of cell mitosis according to wheat variety and chemical agent concentrations. As a result of the study, the key importance of the genotype-mutagenic interaction was demonstrated within the limits of variability of the main indicators of the frequency and spectrum of chromosomal aberrations. It has been established that in the future it will be more optimal to use two varieties whose genotype-mutagenic specificity indicators are significantly higher and one should expect a more significant yield of promising mutant forms from them in the future, especially in combination with SA concentrations in the range of 0.025% and 0.05%. It is demonstrated that the main parameters that reflect genetically determined possibilities in susceptibility to the ecogenetic factor are pollen fertility, the overall frequency of chromosome aberrations, and the number of induced fragments. The use of other parameters displays the trend only partially or does not display it at all, as is the case with the use of rarer types of chromosomal rearrangements. The least promising forms have also been identified for use as starting material in treatments with this substance. It is demonstrated that, in general, this agent is characterized by the same patterns in the induction of cytogenetic activity as for other chemical supermutagens, with some variations depending on the starting material. In the future, it is planned to link the obtained data with the frequency and quality of the resulting hereditary changes, primarily complex biochemical and physiological ones, in order to improve the quality of plant products and various types of plant tolerance to adverse environmental conditions.

“…In terms of interaction between mutagens and new genotypes, those studies still provide a lot of information about the course of complex processes at the level of the genetic apparatus in the first generation after mutagenic treatment (Dwinanda et al, 2020;Nazarenko, 2020). In all the cases, by the sterility reduction, the applied mutagen concentrations should be placed in the moderate range according to the generally accepted classifications (Shabani et al, 2022). However, by the induction of chromosomal abnormalities, they should clearly be classified to the extreme segment of the range of high concentrations (Nazarenko, 2016;Bhat & Wani, 2017).…”

“…At the same time, chemical supermutagens demonstrate an increased affinity with certain DNA regions, which further leads to an increase in the variability (Bezie et al, 2020). It is also necessary to monitor the changes directly influencing the plant viability (Shabani et al, 2022).…”

The analysis of cytogenetic activity is a key component in determining prospects of future hereditary variability after, subject to a certain mutagenic factor, primarily identifying the significance of the genotype-mutagenic interaction, the correctness of the selected concentrations for more thorough screening of some development parameters. Winter wheat seeds of eight varieties (Balaton, Borovytsia, Zeleny Gai, Zoloto Ukrainy, Kalancha, Niva Odeska, Polyanka, Pochayna) were subjected to ЕМS (ethylmethansulfonate) at the concentrations of 0.025%, 0.05%, 0.10% The exposure lasted for 24 hours. Cytogenetic analysis was carried out for pollen fertility; we also examined the rates and spectras of chromosomal rebuildings in proper cell devision phases in relation to plant gcnotype and concentration of the mutagen. The experiment was aimed at identification of interrection between geotype, concentration of mutagen and mutagen nature, determining genome response to mutagen action. Such indicators of cytogenetic activity as the total rate of chromosomal abnormalities, fragments and double fragments, single and double bridges, micronucleus and lagging chromosomes were studied. The selected concentrations of the mutagen significantly influenced all the analyzed parameters, they can be attributed to the optimal and high range of concentrations according to the nature of the impact on bread wheat. We determined that in the case of the mutagenic action, the genotype had a significantly lesser effect on the nature and rate of individual aberrations than an increase in the concentration, while having a significant effect on the rate of increase in pollen sterility. The mutagen was characterized by a significantly lower site-specificity at the cellular level than other chemical supermutagens, manifesting only in the correlation between individual types of aberrations, but not in the character of the increase in their number. The key parameter to identify the activity of this agent was the frequency of fragments and double fragments, their ratio with bridges.
