Morphological Study of some Wild Grape Genotypes of Sardasht and Piranshahr Regions, Iran

Authors

Abstract

To evaluate the variation in morphological traits of some wild grape genotypes in Sardasht and Piranshahr forests and their relationship with Rasha grape cultivar, this research was conducted. In the first year wild grapevine genotypes were identified and marked by plaques based on the sexuality of flowers. In the same regions some plants of Rasha cultivar in vinegards were also marked. In different phenological stages, based on global gene bank descriptor for grape, different traits related to growth end point, young stem, young leaves, mature leaves and fruit were measured and recorded. Results showed differences between various traits in wild genotypes. The frequency ratio of female accessions to male grapes was 3:13. Based on cluster analysis, all genotypes of wild and cultivated Rasha grape were divided into three groups. The first group consisted of genotype PR1 from Piranshahr, in the second group all wild grape genotypes of Piranshahr and Sardasht and in the third group only cultivated Rasha cultivar were located. In this clustering, the high similarity was observed between GH7 and GH5, GH3 and GH6 and PR8, PR3 and PR4, PR5, and PR8, respectively. Rasha cultivar showed very little similarity with the wild grapes.
