Role of scab-resistant apple varieties in forming assortment of new industrial apple plantings (Malus domestica Borkh.)
Journal Title: Plant varieties studying and protection - Year 2015, Vol 0, Issue 3
Abstract
Purpose. Identifying new scab-resistant apple varieties with high biological potential by the set of agronomic characters and the ability to realize it effectively in various soil and climatic conditions. Methods. Field, laboratory, comparison, generalization, statistical ones. Results. The author presents the results of study of 17 scab-resistant non-irrigated apple varieties on a semi-dwarf rootstock as to their adaptability to biotic and abiotic stressors as well as their economic productivity. The studied varieties appeared to be winter-hardy, frost- and heat-resistant, but medium drought-tolerant ones. They are characterized by weak and moderate susceptibility to powdery mildew, high resistance to fruit rot and very low amounts of brown spot, except for Gold Rush variety. Such 10 year old varieties as ‘Edera’, Florina’, ‘Amulet’ and ‘Perlyna Kyieva’ and 8 year old ‘Afrodita’, ‘Vitos’, ‘Orlovskoie Polesie’ and ‘Topaz’ formed the highest productivity during the years of study. Due to the pollen quality and high interfertility, ‘Revena’ and ‘Gold Rush’ varieties were identified as universal pollinators for winter scab-resistant apple varieties. Conclusions. Such ecologically resistant winter varieties as ‘Topaz’, ‘Freedom’, ‘Edera’ and autumnal ‘Remo’, ‘Afrodita’, ‘Vitos’, ‘Amulet’ were recognized as promising for new intensive non-irrigated plantations in the Forest-Steppe zone of Ukraine. They can be the basis of new gardens occupying 25–30% of the area where ecologically safe fruits for various target purposes will be grown supplying demands of the population and processing industry.
