Abstract:

Fruit samples analyzed in this paper were harvested in 2008 and 2009 from seven new sweet cherry cultivars, namely ‘Cetăţuia’, ‘Cătălina’, ‘Bucium’, ‘Golia’, ‘Maria’, ‘Ştefan’, ‘Tereza’, as well as from the cultivar ‘Boambe de Cotnari’, which is most widespread in the Iaşi area, in North-Eastern Romania. The period from flowering to full maturity was between 56–76 days. ‘Cetăţuia’ and ‘Cătălina’ were the earliest cultivars, while ‘Boambe de Cotnari’ and ‘Maria’, the latest ripening ones. Fruit width ranged between 17.0 mm and 23.0 mm and fruit weight ranged from 3.9 g and 7.4 g, but statistical differences between ‘Boambe de Cotnari’, ‘Bucium’, and ‘Maria’ were non-significant. Soluble solids content in different cultivars was between 14.5 °Brix and 17.8 °Brix. The lowest values were recorded in ‘Golia’ and ‘Ştefan’, and the highest, in ‘Boambe de Cotnari’. The lowest values of reducing sugar content were in cultivars ‘Golia’ and ‘Bucium’ (9.5 g 100 g-1 fresh fruit), while ‘Ştefan’ and ‘Cetăţuia’ had the highest reducing sugar content (12.2 g 100 g-1 fresh fruit). Titratable acidity was between 0.5 and 0.9 g malic acid 100 g-1 fresh fruit, ‘Cătălina’ and ‘Golia’ having the lowest values, while ‘Tereza’ and ‘Bucium’ had the largest. The antioxidant capacity of fruits, expressed as mg ascorbic acid 100 mL-1 fruit’s methanolic extract, ranged between 4.2 (in ‘Bucium’) and 18.6 (in ‘Ştefan’). There was a non-significant relationship between the number of days from full bloom until fruit maturation and chemical properties.

Abstract:

During 2001–2010, the following cultivars from the breeding programme of the Polli Horticultural Research Centre of the Institute of Agricultural and Environmental Sciences, Estonian University of Life Sciences were registered: the apples ‘Kaari’, ‘Kaimo’, ‘Karamba’, ‘Katre’, ‘Kikitriinu’, ‘Krista’, and ‘Liivika’, the crab apples ‘Kuku’, ‘Ritika’, and ‘Ruti’, the sweet cherries ‘Elle’, ‘Karmel’, ‘Piret’ and ‘Tontu’, the raspberries ‘Aita’ and ‘Alvi’, and the black currants ‘Almo’, ‘Ats’, ‘Elo’ and ‘Karri’. Since 2004, applications for registration and DUS testing have been submitted for the new apple cultivar ‘Els’, pear cultivars ‘Kadi’ and ‘Polli Punane’, sweet cherry cultivars ‘Anu’, ‘Ene’, ‘Irma’, ‘Kaspar’, ‘Mupi’, ‘Polli Murel’ and ‘Tõmmu’. Apple, plum, sweet cherry, black currant and raspberry breeding programmes are going on as part of the public breeding program. Winter hardiness is the first-rate goal in all crops. In apple, breeding for scab resistance is now the main task. In the nearest future, some new plum, apple and black currant cultivars will supplement the breeding results of the institution at Polli.

Abstract:

In spring 2002, nine clonal rootstocks: the German ‘Gisela 5’, the Russian ‘LC-52’, ‘OVP-2’, ‘OVP-3’, ‘VC-13’, ‘VSL-2’, ‘V-2-180’, ‘V-2-230’ , ‘V-5-172’ and Prunus mahaleb L. seedlings (control), were planted at a nursery of Polli Horticultural Institute and in late July the sweet cherry cultivar ‘Kristiina’ and three selections ‘Karmel’, ‘Polli 10/8’ and ‘Polli 6/2’ were budded on them. The highest bud take percentages were observed on V-2-230, OVP-2, and V-5-172. Incompatibility between ‘Karmel’ and several rootstocks was noted. The growth of one-year-old plants at the nursery was most vigorous on P. mahaleb seedlings, OVP-2 and OVP-3 and the weakest on VC-13. The trunk diameters of the clonal rootstocks were significantly smaller than those of the control rootstocks.
