Analysis of variability of morphological characteristics of Japanese camellia varieties (Camellia japonica L.) In the conditions of protected ground of the city Moscow

In the present work, the analysis of the variability of quantitative and qualitative morphological traits of Japanese Camellia (Camellia japonica L.) varieties used in greenhouses of botanical institutions in Moscow is considered. The paper considers the following varieties: ‘Governor Mouton’, ‘Madame Lebois’, ‘Covina’, ‘Bella Toscana’, ‘Bonomiana’, ‘Alba Simplex’, ‘Lavinia Maggi’, ‘ Silver Waves ’,‘ Doncklaeri ’. To assess the variability, 10 characters were selected, six of which describe the leaf (leaf blade length, leaf blade width, leaf ovality index, leaf blade base shape, leaf blade apex shape, leaf blade shape) and four – flowers (corolla color, flower diameter, degree of terry and aroma). The variability of quantitative characteristics was assessed by determining the confidence intervals method and calculating the coefficients of variation. The variability of qualitative features was assessed by establishing modalities and determining modes. It is noted that, in terms of quantitative and qualitative characteristics, weak variability is observed in most cases. Thus, the studied varieties of Japanese camellia have stable features that characterize the flower and leaf blade.
