| dc.description.abstract | Estonian apples have always been popular in Latvia. At present, ‘Tiina’ is widely grown commercially as well as in home gardens, and ‘Liivika’ is promising for organic and home orchards. A number of new Estonian apple cultivars and hybrids have been screened in 1990–2020. Several new selections by breeder Kalju Kask (Polli) are included in field trials at Institute of Horticulture - ‘Aule’, ‘Kastar’ and KK 201-2 (‘Karlote’) since 2011, ‘Kersti’ since 2014, KK 5-16 (‘Kelin’) with scab resistance gene Rvi6 and KK 2812 since 2015. Their trees were planted on dwarfing rootstock B.9 as one-year-old whips at distances 1.5×4 m, in 3 to 5 replications with 2 or 1 trees. Commercial cultivars ‘Auksis’, ‘Antei’ and ‘Zarya Alatau’ were used as controls. The highest productivity had ‘Aule’ and ‘Kastar’, the best fruit quality - ‘Aule’ and ‘Kelin’. ‘Aule’ has been highly esteemed also by some Latvian farmers. Fruits of ‘Kelin’ had the best storage, which is crucial for a cultivar’s commercial success in Latvia. On the other side, ‘Kersti’ proved to be unsuitable for Latvian conditions, having very strong tree vigour and low yields. ‘Kastar’ showed a high tendency to fruit cracking at calyx, while KK 201-2 and KK 2812 had irregular or low yields. Of newer acquisitions, scab resistant (gene Rvi6) ‘Virve’ and KK 4-11 show good preliminary results and have been propagated for trials on dwarfing rootstocks. Productivity, tree characteristics, fruit quality traits and taste panel evaluation of Estonian apples in Latvia are discussed. | eng |
