ÇAYKARA (TRABZON, TÜRKİYE) İLÇESİNDE YETİŞTİRİLEN YEREL ARMUT (Pyrus spp.) GENOTİPLERİNİN SELEKSİYON YOLUYLA ISLAHI: II-AĞAÇ ÖZELLİKLERİ
BREEDING BY SELECTION OF LOCAL PEAR (Pyrus spp.) GENOTYPES GROWN IN ÇAYKARA COUNTY (TRABZON PROVINCE, TURKEY): II-TREE TRAITS

Summary/Abstract: This study was carried out in Çaykara County (Trabzon province, Turkey) and in its 25 districts in 2012 and 2013. In the study genotypes according to the first year harvest dates were divided into 3 groups as summer, autumn and winter seasons. Total 34 local pear genotypes (18 summer, 9 autumn and 7 winter seasons) were determined as promising according to weighted-ranked method. In the research, tree traits and the susceptibility to fire blight of the genotypes were investigated by PCR method. Bud burst time, full blossoming time and harvest time changed between 18.02-19.03, 30.03-20.04 and 06.07-18.08 in the summer seasons; 18.02-19.03, 30.03-20.04 and 06.07-18.08 in autumn seasons; 20.02-19.04, 25.03-14.05 and 10.08-27.09 in winter seasons, respectively. Alternate bearing is not observed in all genotypes. On the other hand, the fire blight disease was not seen the susceptibility genes that consider as molecular on promising genotypes.
