</bold>The genetic differentiation of light and shadow phenotypes of <italic>Plantago media</italic> plants was evaluated using intersimple sequence repeats (ISSR) markers.</p> <p><bold>Results.</bold> The population-genetic analysis of 210 loci revealed two clusters, which boundaries coincided with the boundaries between plants of light and shadow phenotypes. The results of the discriminatory analysis of the main components and AMOVA (<italic>F</italic><italic><sub>ST</sub></italic> = 0.07, <italic>p</italic> = 0.001) confirmed that there are statistically significant genetic differences between these phenotypes even though they possess a high genetic similarity.</p> <p><bold>Conclusion.</bold> Light and shadow <italic>Plantago media </italic>phenotypes adapted to different ecological conditions are genetically differentiated. The population genetic analysis using ISSR markers is a sensitive tool for identifying the genetic diversity of phenotypic plant variations formed under the influence of environmental factors.</p></abstract><trans-abstract xml:lang="ru"><p>Исследован уровень генетической дифференциации двух фенотипических вариаций <italic>Plantago media</italic> L. на Южном Тимане. Популяционно-генетический анализ с использованием межмикросателлитных маркеров (ISSR) по 210 локусам выявил два кластера, границы которых совпадали с границами между растениями светового и теневого фенотипа. Результаты дискриминационного анализа главных компонент и AMOVA (<italic>F</italic><italic><sub>ST</sub></italic> = 0,07, <italic>p</italic> = 0,001) подтвердили, что на фоне высокого генетического сходства существуют статистически значимые генетические различия между этими фенотипами.
