Induced Mutations of Winter Wheat Caused by Gamma-Rays Fixed on Plant Height and Stem Structure

Abstract: The objectives of our investigations are to describe the variation by mutations of stem architecture of the main groups of modern Ukrainian winter wheat varieties (8 varieties) due to their interactions with dose specific. Agronomic-value traits like as general short stem, dwarfs and semi-dwarfs have been investigated too. New perspective mutant lines have been obtained in terms of investigation. Main components for mutation breeding successful was genotype-mutagen interaction (due to factor analyses). By sens… Show more

“…General rate of mutations was up to 14.0% under DAB 0.2% action (Sonechko) and to 9.8% under DAB 0.1% action (Sonechko too) (table 1), but for the most part of genotypes was on the level 7-9% for DAB 0.2% and 6-8% for DAB 0.1%. Regarding this date difference between concentrations of DAB not so strong as between doses of gamma-rays at previous investigations (Nazarenko et al, 2019).…”

“…Regarding other types it's not possible. Especially interested in semi-dwarf mutations which have a key value for identification for gamma-rays (Nazarenko et al, 2019). Value of partial Lamba is enough only for using two first traits as features for precision analysis.…”

“…По-друге, від природи мутагену -гамма-радіація, як і більшість фізичних чинників, за своїми наслідками належить до мутагенних факторів з високим ступенем мутагенної депресії (Hiroyasu, 2018;Kolakar et al, 2018;Nazarenko et al, 2018). У наших дослідженнях гамма-промені завжди призводили до найгірших наслідків за всіма показниками (Nazarenko et al, 2019;Nazarenko, 2015).…”

“…Низьким ефектом шкодочинності у першому поколінні характеризуються деякі групи хімічних агентів, котрі здатні індукувати суттєву кількість змін при менш вагомому погіршенню онтогенетичних параметрів рослин [4,5]. Також для покращення проблем з схожістю та виживанням, зниження депресії продуктивності іноді використовують речовини-антимутагени [8] та вихідний матеріал з підвищеною стійкістю до несприятливої дії [6,7].…”
