Abstract

Purpose: Selection and evaluation of imported cultivars is one of the main programs for the breeding of fruit trees, including pears. Comparison of quantitative and qualitative traits of imported cultivars and genotypes with available cultivars of each region is necessary to obtain superior cultivars and introduce them to producers. Research method: In this study, the growth and yield of 10 introduced Asian pear genotypes named Ks6, Ks7, Ks8, Ks9, Ks10, Ks12, Ks13 and Ks14 along with two European pear cultivars named 'Shahmiveh' and 'Spadona' as controls grafting on 'Dargazi' seedling rootstock were studied during five years (2015-2019) in the climatic conditions of Isfahan (Iran). Findings: The highest rootstock, grafting, and scion diameter as well as the highest tree height were observed in 'Shahmiveh' and 'Espadona' cultivars. Ks8 and Ks9 had the lowest rootstock and grafting diameter and Ks10 showed the lowest scion diameter and tree height. Two European pear cultivars, 'Shahmiveh' and 'Espadona', had lower yield and yield efficiency than Asian genotypes. The highest yield and yield efficiency belonged to Ks13 and Ks8, respectively. 'Shahmiveh' and Ks9 had the highest and lowest fruit dimensions, respectively. European cultivars had higher TSS than Asian genotypes. The highest and the lowest fruit firmness were observed in Ks13 and 'Shahmiveh', respectively. Research limitations: No limitations were found. Originality/Value: In general, Ks13 and Ks8 are recommended for cultivation and expansion in the climatic conditions of Isfahan due to their good yield and taste index.
