BACKGROUND:Haskap (Lonicera L.) is as a new perspective berry species for growing in temperate region climate. According to nowadays knowledge haskap is absolutely self-sterile species hence the studies on pollination mode are required. OBJECTIVE:The aim was to evaluate new haskap cultivars of Canadian and Russian origin in terms of their matching for cross-pollination. METHODS:The overlapping of flowering time of cultivars for mutual cross pollination was selected. The effectiveness of pollination was assessed: in terms of pollen tube overgrowth through the pistil tissue and the quality of set fruit. RESULTS:The Russian cultivars bloomed much earlier than the Canadian cultivars. The stigma is most receptive in the freshly open flower stage and directly after the anther burst. The minimum qualitatively acceptable weight of a berry is 1 g, which corresponds to the formation of about 6 seeds in the fruit. The most compatible pairs of cultivars were: ‘Aurora’בJugana’, ‘Aurora’בSinij Utes’ and ‘Aurora’בVostorg’. CONCLUSION:The Russian cultivars bloomed much earlier than the Canadian cultivars, the stigma is most receptive in the freshly open flower, minimum qualitatively acceptable weight of berry is 1 g (what represents 6 seeds in fruit), best mutual pollinating cultivars are the cultivars within the same breeding group (Russian x Russian and Canadian x Canadian)

花的形态性状评价和 haskap (Lonicera L) 品种根据其来源杂交的可能性

背景:哈斯卡普(Lonicera L.)是一种生长在温带气候下的新型浆果品种。根据现在的知识,haskap 是绝对自不育的物种,因此需要对授粉方式进行研究。目的:目的是评估加拿大和俄罗斯来源的新 haskap 品种的异花授粉匹配。方法:选择互花授粉品种开花时间重叠。评估授粉的有效性:通过雌蕊组织的花粉管过度生长和果实的质量。结果:俄罗斯品种比加拿大品种开花早。柱头在新开的花期和花药爆裂后最容易接受。浆果质量上可接受的最小重量为 1 克,这对应于果实中约 6 粒种子的形成。最相容的品种对是:'Aurora'×'Jugana'、'Aurora'×'Sinij Utes'和'Aurora'×'Vostorg'。结论:俄罗斯品种比加拿大品种开花早得多,柱头在新开的花中最容易接受,浆果质量可接受的最小重量为1 g(相当于果实中的6粒种子),最佳互花品种是内部的品种。相同的繁殖组(俄罗斯 x 俄罗斯和加拿大 x 加拿大)
