Identification and registration of some grape cultivars by usmg morphological characteristics

Unique genetic resources and abundant plant and animal are the main land of vast wealth and investment in Iran. The present project was conducted in order to distinguish and registration the most important grape cultivars of Iran based on morphological and physiological traits in the International Union for the Protection of New Varieties of Plants (UPOV).This reasearch was conducted in Qazvin Province (Takestan Grape Research Station) and West Azerbaijan (Urmia research station) on Fakhri, Pykamy Kashmar, Khvshnav, Rish Baba Sefid, Rish Baba Ghermez, Sefid Bidaneh, Shahrodi, Shast Arous, Yaghoti, Askari, Ghermez Bidaneh and Mish Pestan. Measured, recorded and evaluated more than 50 vegetative and reproductive traits were based on Guidelines for the Conduct of Tests for Distinctness, Uniformity and Stability in grapes cultivars in development and growth stages of grape plant and fruit during 2009-2011.Results showed application of quantitative or qualitative traits alone was unable to distinguish from together all the grape varieties studied. But using combination of some qualitative and quantitative properties as the key attributes yielded the full performance in distinguish varieties. So that studied cultivars were distinct from each other completely, only with application rates of eleven qualitative and quantitative traits such as number of consecutive tendrils, shape of blade, profile in cross section, number of lobes, shape of teeth, raipening formation of seeds seed formation (as a plant code) or presentation of four characters, including fruit color, seed formation, profile in cross section and tendril length over the full cross-section of leaf varieties studied were completely distinct from each other. On this basis, can be stated that registration of qualitative and quantitative traits is one of the safest and best practices to distinguish grape varieties from each other and perhaps, except in certain cases, does not require other measurements including genetic fingerprinting.
