Abstract
Relevance. The use of chemical mutagenesis on garlic is relevant for the creation of new forms with stable characteristics, better biochemical qualities, increased yield, for use in breeding practice.
Results. The reaction of garlic treated with two chemical mutagens was evaluated: DES (diethyl sulfate) – 0.025; 0.05 and 0.1% (mutants 2, 3 and 4), as well as DMS (dimethyl sulfate) – 0.02; 0.04 and 0.08% solutions (mutants 5, 6 and 7). The aftereffect of chemical mutagens was noted with low and medium variability of signs in the second–fifth generation. According to the low variability of 1.6–9.4%, the height of plants (samples M 3 and 6), the number of leaves (M 5), the height of the false stem (M 3), the diameter of bulbs (M 6), as well as the length of leaves and the weight of bulbs samples M 3, 5 and 6 were distinguished. The effect of mutagens on morphometric signs of garlic were also tracked in the second generation (re-growing from air bulbs), where the parameters of low and medium variability of signs are marked. The majority of samples on 7 signs reflected a low variability of 5.5–10.0% and only 2 mutants showed an average variability of 11.4–16.4%: M 6 in plant height and false stem and M 3 in bulb diameter and yield. The correlation between their value in the 5th generation and in the 2nd generation also revealed strong direct and average connections. High heritability of h2 signs = 0.74–0.99 for DES preparations – 0.05%, VMI – 0.02 and 0.04%, was the most important indicator of the selection of valuable signs.
