Abstract

The effect of Triton X-100 (TX-100) on the ratio of phenotypic classes and the expression of morphological traits in the progeny of sugar beet hybrids (No. 12 and No. 2) was investigated. It was shown that the TX-100 exposition on the unopened flower buds of sugar beet plants has different effects on hybrid progenies. In agamospermous progeny of hybrid plant N12ct-4, a significant decrease in the heteroallelic (heterozygous) phenotypic classes of alcohol dehydrogenase (ADH1) fraction was determined. The progeny of hybrid plant N2ct-2 did not express the traits of agamospermous origin, but the appearance of sugar beet seedlings with one cotyledon leaf was detected in it. The obtained results indicate high efficiency of the epimutagenic effect of TX-100 on the early stages of plant ontogenesis.
