Abstract
The present research was carried out to collect and assess grape cultivars from different aspects such as cold tolerance, fruit quality, cluster marketability, cluster density, berry quality and size, and introduce the best cultivars of Qazvin province. During 2000-2002, superior and healthy genotypes were identified, and 5 plants from each cultivar or genotype were labeled in different orchards. Finally, 19 cultivars with local names of Mesghali, Mollaei, Fakhri, Shahani Qazvin, Yaghouti, Asgari, Shast-e-Arous, Shani Gerd (Shahani Siah), Yazdandaei, Kareroye Sefid, Kareroye Ghermez, Siah Qazvin, Mishpestan, Bidaneh Sefid, Talaei, Shahroodi, Bidaneh Ghermez, Shani Sefid and Rishbaba were identified. During 2001-2002, different characteristics and phonological stages were recorded on the labeled stock plants using grape descriptors. In March 2001, 20 cuttings were prepared from the stock plants, and cultured in nursery for rooting. Then, 9 plants from each genotype were transplanted to the collection gardon at the Takistan Grape Research Station for further evaluations in the second phase of the project. In the first phase, genotypes showed wide variation for the measured characteristics, so that, among them genotypes of early ripening to late ripening, seedless and seeded, low to high yield, very small to large fruit, early to late flowering, low to high sugar content, different vegetative characteristics, weak to power vigor etc. were observed. Cultivars Fakhri, Shast-e-Arous and Mishpestan had very large berries Yaghouti, Asgari, Bidaneh Sefid and Bidaneh Ghermez contained imperfect seed Shast-e-Arous and Shahroodi had very large clusters Kareroye Sefid and Kareroye Ghermez contained female flower with reflex stamens Shahani, Yaghouti, Yazdandaei and Shani Gerd had very early ripening fruit Siah Qazvin had late ripening fruit Shast-e-Arous and Shahroodi had Good storage ability Fakhri, Asgari, Shast-e-Arous, Shani Gerd, Shahroodi and Bidaneh Sefid had high Brix.
