| Abstract | The aim of the study was to investigate the seed productivity of Canna hybrida Hort. varieties and clones of Ukrainian and foreign breeding under the conditions of the Pryluky Experimental Station of the Institute of Gardening of the NAAS. The study material included varieties and clones of one cultivar type Canna x crozy Hort. bred at the Pryluky Experimental Station (Adagio, Isida, Lyubava, 14-07-21, 05-03-21), Nikitsky Botanical Garden (Maestro, Vostok-2), and foreign breeding (Yellow King Humbert). It was established that the varieties and clones of Canna hybrida are capable of fruit formation under the conditions of the northern part of the Left-Bank Forest-Steppe of Ukraine. Varieties and clones developed at the Pryluky Experimental Station of the Institute of Gardening demonstrated the highest morphological, biometric, and seed quality indicators, being better adapted to the conditions of the Left-Bank Forest-Steppe. It was noted that the Lyubava, Adagio, and Isida varieties, as well as clones 14-07-21 and 05-03-21, exhibited annual fruiting, whereas Maestro and Vostok-2 varieties fruited only under favorable weather conditions. The most productive were the Lyubava (29.2 fruits per bush), Adagio (26.3 fruits per bush) varieties, and clones 05-03-21 (39.3 fruits per bush) and 14-07-21 (22.7 fruits per bush). Varieties and clones of the Pryluky Experimental Station had a higher 1000-seed weight compared to varieties from the Nikitsky Botanical Garden and the foreign variety. This suggests that adapted plants contain a greater amount of perisperm tissue in their seeds. Lyubava and clone 05-03-21 showed the largest seed dimensions (8.33 × 6.68 mm and 8.45 × 6.28 mm), 1000-seed weight (244.6 g and 271.77 g), and high germination rates (87 % and 88 %). The shortest seed germination period (up to 7 days) was recorded for the Adagio variety. The highest laboratory germination (88 %) was determined for the seeds of clone 05-03-21. | ||
