Article A Selection Study on Determining Important Characteristics of Almond Trees in Turkey(1996) Kalyoncu, I.H.; Sen, S.M.In this study, carried out in 1988, 450 almond trees Amygdalus communis L.) were examined to select the important quality fruit types in natural almond population grown around the Apa Dam Lake in Cumra, Konya, Turkey, and of them 12 types were selected with regard to fruit characteristics. All selected types were seen to have the characteristics of late flowering. The average inshell fruit weights were between 3.,37 g and 5.24 g. The kernel weights were 0.64 and 1.00g and the ration kernel were 14.29% and 20.01%. All types had extremely hard shell almond characteristics.Conference Object A Study on the Genetic Variability and Selection of Superior Walnut (Juglans Regia L.) Trees Within Seedling Population Ofaround of Van Lake(International Society for Horticultural Science, 2001) Akça, Y.; Sen, S.M.This study was conducted out to determine genetic variabilitiy and to select superior walnut trees within seedling population of around of Van Lake in 1993 - 1995. In this study were examined over 25.000 walnut trees with high heterozygosity from point of yield (lateral fruitfulness %), tolerance to anthracnose and nut quality factors. The seedling population of around of Van Lake, exhibits tremendous genetic variation in different aims of walnut breeding. 23 types were selected according to yield, tolerance to anthracnose, diseases and pests and nut quality. In these types average nut weight, varied from 9.36±0.8 to 18.60±1.3 g, kernel weight varied 6.09±0.8 - 9.58±0.8 g, kernel rations varied from 50.89% to 65.17 %, shell thickness varied between 0.91±0.1 - 1.76±0.1 mm and nut diameter varied from 29.93±0.9 to 40.44±1.3 mm.Conference Object Study on the Selection of Superior Walnut Trees in Hizan (Bitlis) Populations(International Society for Horticultural Science, 2001) Akça, Y.; Sen, S.M.This study was conducted out to determine genetic variability and select superior walnut types within seedling population of Hizan (Bitlis). Hizan climatic environment is unsuitable for walnut trees. Walnut trees in Hizan population are generally tolerant to winter cold and late spring frost. Hizan seedling population exhibits tremendous genetic variation in pomological and phenological characteristics. Lateral fruitfulness of selected types are highest and leafing time is very late according to another trees. Selected type can use for walnut improvement as genetic resources . Nut quality of these types are not as good as of any standard walnut cultivar. But these types must be collected and propagated in research centre. In selected types nut weight varied between 7.49±0.75 - 13.93±0.75 g kernel weight varied between 2.61±0.13 - 5.73±1.13g, shell thickness changed 1.32±0.33 - 2.45±0.44 mm and nut diameter varied between 22.30±1.1232. 26±2.95 mm. Range of variation in nut colour is between dark brown to dark yellow.
