ABSTRACT
To estimate genetic relationships among 46 local grape cultivars, RAPD analysis was performed with 25 decamer primers selected from a total of 60 primers. Genetic relationships among these cultivars were determined by calculating similarity indexes, from which a dendogram was derived. There was high genetic variation among the cultivars, with values of genetic diversity ranging from 0.553 to 0.952 using the Jaccard coefficient. UPGMA analysis of a distance matrix produced a dendogram with six clusters. The relatively high genetic similarity ratios observed for the cultivars was also reflected in the dendogram. In general, no relationship was encountered between the genetic similarity ratios of the cultivars and the results of previous ampelographic analyses.

The aim of this study was comparatively to examine herbal traits of the cultivars such as Rubin, Summit, Holland Dwarf, Heritage, Tulameen, Aksu Red, Nuburg, Canby and Willamette red raspberries cultivated at Ankara Condition, in the capital of Turkey between 2002 and 2005. According to Repeated Random Complete Design (RRCD) (which was composed of four random plot design experiments) used in the experiment, the effects of cultivar, year and cultivar by year interaction on herbal traits such as the height of shoot, diameter of shoot, number of shoot, fruitfulness of shoot and weight of fruit were further more significant (p < 0.0001). Besides, determination coefficients of RRCD for traits ranged from 95.60 to 99.94% (very-high). As a result, we concluded in Ankara condition that as to herbal traits such as the height of shoot, diameter of shoot, number of shoot, fruitfulness of shoot and weight of fruit, Willamette cultivar were more superior to others. In addition, we can suggest that researchers should analyze using RRCD because Determination Coefficients of RRCD for all traits were much more found.
