This experiment was carried out on Souri and Zeni grape cultivars during 2001-2002 seasons to determine their fertility and some other characteristics besides the position of flower cluster on shoots under head training system with four-five eyes spurs. Data showed that the two cultivars had an average of fertility 47.16 % and 58.9 % for Souri and Zeni during 2001-2002, respectively and these percentages can be increased by using other training and pruning systems. The position of flower cluster is a stable genetic characteristic. The climate factors had no effect on fertility and the flower cluster position and on some other characteristics of these two grape cultivars.
