An Evaluation on Yield Potential in Walnut (Juglans Regia L.)

Abstract

In this study, yield potentials of Juglans regia selections were determined during two years 1996 and 1997 in the district Van (Turkey). A formula based on productions (%) and average numbers of pistillate flowers on terminal and lateral shoots was used. For this aim, yield index scores belonging to promising selections in terms of fruit characteristics were calculated. Yield potentials were classified in four groups low, middle, good and very good based on these scores. Consequently, five selections were considered as very good for yield potential.
