The relationship of the efficiency of energy conversion into growth as an indicator for the determination of the optimal dose for mutation breeding with the appearance of chromosomal abnormalities and incomplete mitosis after gamma irradiation of kernels of Triticum turgidum ssp. durum L.

Abstract: The study aim was to determine the optimal gamma irradiation dose for mutation breeding in Triticum turgidum ssp. durum L. Root, shoot and seedling growth, as well as the efficiency of energy conversion into growth were determined to examine the growth retardation effects of gamma irradiation that are the result of DNA damage (bridges, ring chromosomes, micronuclei, incomplete mitosis) in Triticum turgidum ssp. durum L. The kernels were irradiated with doses of 50, 150, 250 and 350 Gy using a 60Cobalt gamma-ra… Show more

“…Embryos produced on both media were used in the EMS treatment. EMS is the most widely used chemical mutagen in mutation breeding, considering its high effectiveness and ease of handling (ease of detoxification through hydrolysis for disposal) compared to other chemical mutagens of the same group such as nitroso compounds [ 29 , 32 , 74 ] or physical mutagens that result in chromosomal aberrations [ 29 , 30 , 75 , 76 ]. Therefore, we optimised the dosage of EMS for mutation induction in the three valuable cultivars that we used in our somatic embryo induction studies.…”
