Biological and productive characteristics of apple cultivars resistant or tolerant to scab [Venturia inaequalis (Cooke) Wint.]

摘要

Biological and productive characteristics of 11 scab-resistant apple cultivars were studied in the period 2011-2012 on the estate of the monastery ?i?a in Central Serbia. Control cultivar for comparison was ‘Idared’, as the most spread apple cultivar in Serbia. The earliest blooming was found in cultivar ‘Topaz’, and the latest in cultivar ‘Rewena’. Based on the time of fruit maturation, three cultivars belong to the summer and autumn group, and five cultivars belong to the winter group. The strongest vegetative growth was found in cultivars ‘?ampion’, ‘Prima’, and ‘Florina’, while the highest yield was obtained in cultivars ‘Remura’ and ‘Goldrush’. The best fruit quality was found in cultivars ‘William’s Pride’, ‘Rewena’, ‘Enterprise’ and ‘Florina’. [Projekat Ministarstva nauke Republike Srbije, br. TR 31063 i br. III 46013]
