Abstract

Fruit yield efficiency and some vegetative characteristics of commercial and spur type apple. cultivars was evaluated in Dr. Nakhjavani field station, Orumieh, Iran, in 2008 and 2009 growing seasons. Apple cultivars included: Red Spur, Red Chief, Golden Spur, Yellow Spur, Fujii, Red Delicious, Cooper Spur, Red Cooper Spur, Jonathan, Golden Delicious, Oregon Spur, Jonagold. The experimental design was randomized complete block design with three replications. Scions of these cultivars were grafted on M111. Results showed that highest and lowest vegetative growth were observed for Red Delicious and Red Spur, respectively. Red Spur had the highest fruit yield efficiency with 0.693 kg cm-2. Fujii and Jonathan had the highest (17.96%) and the lowest (12.05) of TSS, respectively. Considering fruit yield efficiency, spur type apple cultivars are suitable to be grown in climatic conditions similar to Orumieh.
