Adaptability and productivity of golden currant varieties and selected forms breeding in Lisavenko Research Institute of Horticulture of Siberia

Winter hardiness and productivity estimation of 13 golden currant varieties and selected forms breeding in Lisavenko Research Institute of Horticulture of Siberia have been done in years 2011-2015. Evaluation of climate condition during years of investigation has been carried out. Level of climate infl uence on plants has been detected. It was established that all samples have suffi cient adaptability to extreme weather conditions of Altai. The overwintering of plants, including severe conditions in the autumn-winter period of 2012/13 was passed safely without freezing of branches and generative buds. Due to increased air temperatures in year 2014, the vegetation was started earlier compared to mean data. At the end of April, there was frost, that damaged part of the fl oral buds in the brush. As a result of estimation, some varieties like Levushka and Otrada as well as several hybrids resistant to freezing of fl ower buds by spring frosts have been selected. Flowering both of varieties and elite forms were abundant (4,0-5,0 points). The yield of estimated varieties was ranged from 2,0 up to 6,5 kg per bush (5,0-16,3 t/ha), weight of berries was from 0,6 to 3,8 g. The varieties Otrada, Levushka, Yubiley Altaya has been selected for high productivity (11,5; 10,8; 9,0 t/ha respectively). Some other varieties have been also selected for high productivity: 4197-06-1, 4189-06-9 3685-99-13 and 4190-06-13. Productivity of Ida and Otrada varieties as well as variety under selection 4190-06-4 is resistant regardless of weather conditions, the variation index is 3,4- 9,5%. The weight of berries depends on many factors, including climate conditions of the year. In years 2013 and 2014, the amount of precipitation during the vegetation period was higher compared to other years, that infl uenced in increasing of weight of berries up to 9,0-33,0 %.
