YIELD, ECONOMICALLY VALUABLE INDICATORS AND CHEMICAL COMPOSITION OF BLUE HONEYSUCKLE UNDER CONDITIONS OF SAKHALIN TRADE-WIND LITTORAL CLIMATE

Abstract

The blue honeysuckle is the earliest ripening berry, which ripens 7–10 days earlier than the garden strawber-ries under the conditions of Sakhalin's climate. It is resistant to lower fungi and parasites and can be cultivat-ed without pesticides. Currently, many honeysuckle varieties with fruits of different morphologies and chemical composition have been bred. We analyzed values of economically valuable indicators and chemical composition in 14 varieties of honeysuckle, which grow in the monsoon climate of Sakhalin. To assess the most productive variety, the values of each character were presented as percentage of the maximum for each indicator. Knowing the total values of characters under investigation made it possible to choose the best va-rieties, from authors` point of view, to grow in the household gardens in the monsoon climate of Sakhalin: from the Pavlovsk Experimental Station of Vavilov Institute of Plant Industry – Leningradsky giant (506.4%), Berel (432.9%) and Viola (423.4%).
