Sinine kuslapuu (Lonicera caerulea L.) on Eestis üha enam tähelepanu pälviv marjakultuur, mille kasvatamist piirab endiselt piiratud teave sortide sobivusest kohalikes tingimustes, eriti mehaanilise koristuse kontekstis. Varasemad uuringud on näidanud, et sortide vahel esineb märkimisväärne varieeruvus nii saagikuse, viljade kvaliteedi kui ka tehnoloogiliste omaduste osas, kuid Eesti tingimustes on vastavaid võrdlusuuringuid tehtud suhteliselt vähe.
Käesoleva magistritöö eesmärk oli hinnata 2025. aasta katseandmete põhjal nelja sinise kuslapuu sordi (’Boreal Blizzard’, ’Boreal Beauty’, ’Jugana’ ja ’Vostorg’) saagikust, viljade kvaliteeti ja sobivust mehaaniliseks koristuseks.
Uuring viidi läbi Eesti Maaülikooli Polli aiandusuuringute keskuse katseaias, kus hinnati sortide saagikust, viljamassi, mehaanilise koristuse efektiivsust, varisemist ning viljamahla keemilisi näitajaid (lahustuvad kuivained ja orgaaniliste hapete sisaldus). Andmete analüüsiks kasutati dispersioonanalüüsi (ANOVA) ja Tukey mitmikvõrdluste testi.
Tulemused näitasid, et sordid erinesid oluliselt nii saagikuse kui ka tehnoloogiliste omaduste poolest. Kõrgeima saagikusega oli ’Boreal Beauty’, samas kui ’Jugana’ eristus kõige suurema mehaanilise koristustõhususe poolest. ’Boreal Blizzard’ puhul jäi suurem osa saagist põõsale, kuna kombain ei võimaldanud alumisi oksi koristada. Viljade keemilise koostise osas eristus ’Vostorg’ kõrgema lahustuvate kuivainete sisaldusega ning ’Boreal Beauty’ suurema orgaaniliste hapete sisaldusega. Tulemused olid üldjoontes kooskõlas varasemate uuringutega, kus ilmnes sarnane sortidevaheline varieeruvus.
Uuring kinnitab, et sortide sobivus mehaaniliseks koristuseks sõltub mitme faktori koosmõjust ning ei ole määratav üksiku näitaja põhjal. Tulemusi saab rakendada sordivalikul tootmistingimustes ning loovad aluse edasisteks mitmeaastasteks uuringuteks, mis võimaldaksid täpsemalt hinnata sortide stabiilsust ja sobivust Eesti tingimustes.
Blue honeysuckle (Lonicera caerulea L.) is a berry crop that has been gaining increasing attention in Estonia; however, its cultivation is still limited by insufficient knowledge about the suitability of different cultivars under local conditions, particularly in the context of mechanical harvesting. Previous studies have shown considerable variability among cultivars in terms of yield, fruit quality, and technological characteristics, but comparative studies under Estonian conditions remain relatively limited. The aim of this master’s thesis was to evaluate the yield, fruit quality, and suitability for mechanical harvesting of four blue honeysuckle cultivars (‘Boreal Blizzard’, ‘Boreal Beauty’, ‘Jugana’, and ‘Vostorg’) based on experimental data from 2025. The study was conducted at the experimental orchard of the Polli Horticultural Research Centre of the Estonian University of Life Sciences. The evaluated parameters included yield, fruit mass, efficiency of mechanical harvesting, fruit drop, and the chemical properties of fruit juice (soluble solids and content of organic acids). Data were analyzed using analysis of variance (ANOVA) and Tukey’s multiple comparison test. The results showed that the cultivars differed significantly in both yield and technological characteristics. ‘Boreal Beauty’ had the highest yield, while ‘Jugana’ exhibited the highest mechanical harvesting efficiency. In the case of ‘Boreal Blizzard’, a larger proportion of the yield remained on the bush, indicating stronger fruit attachment or later ripening. Regarding chemical composition, ‘Vostorg’ stood out for its higher soluble solids content, whereas ‘Boreal Beauty’ had a higher content of organic acids. Overall, the results were consistent with previous studies that reported similar cultivar-related variability. The study confirms that the suitability of cultivars for mechanical harvesting depends on the interaction of multiple traits and cannot be determined based on a single parameter. The findings can be applied in cultivar selection under production conditions and provide a basis for further multi-year studies to more accurately assess cultivar stability and suitability under Estonian conditions.
