The Determination ofPromisingGenotypes in Native Walnut (Juglans regia L.)Populations of Hani (Diyarbakır) District

Özet

This study was carried out to determine the promisingwalnut genotypes, to two years (2017-2018) in the Hani district of Diyarbakır province. In this study,19 genotypes were selected as promising from about 4000 seeds originwalnut trees. In these selected genotypes, the fruit weights were between 10.03-15.46 g, kernel weights were between 5.00-6.77 g, kernel rates from41.18%to53.65%, shell thicknesses were between 1.47-2.03 mm. In selected genotypes shell color as ‘light’ for 13 genotypes, as ‘dark’ for 6 genotypes; inner shell color as ‘light’ for 6 genotypes, as ‘yellow’ for 9 genotypes and as ‘dark’ for 4 genotypes. Bloominghabits of promising genotypeswere protandrousin 14 genotypes, protogynous in 1 genotype and homogamousin 1 genotype. The lateral fruitfulness ratio was found to be between 0.00% to -100.00 %.
