COMPARATIVE STUDIES ON THE MORPHO-BIOLOGICAL CHARACTERISTICS OF A PERSIAN WALNUT (JUGLANS REGIA L.) POPULTATION FOR SELECTING THE SUPERIOR GENOTYPES

In order to select the superior genotypes for improvement program or for direct production, the comparative studies were carried out on the morpho-biological characters on Persian walnut population, in Khalat-Pooshan Research Station, in Tabriz University, during two years (2000 and 2001). In this study 50 different characters were considered in relation with climatic condition for genotypes evaluation. The means of data for all characters were compared using Dancunʹs Test and their morfo-biological characteristics relation were evaluated by cluster analysis, finally the superior genotypes were selected. According to the results the genotype No. 12 for fruit and kernel weight, genotype No. 13 for kernel yield, genotype No. 17 for late leafing and blooming characters, genotype No. 3 5 for long pistil effective pollination period and genotype. No. 37 for long anthesis period and lateral bearing were selected. In addition, in this study, 4 homogame, 17 prothandre and 27 protogyne genotypes were identified.
