Study of Compatibility and the Effect of Pollen of Some Grape Cultivars on Fruit set and Quantitative and Qualitative Characters of Fruit, cv. Rish Baba Sefid

Grapes have perfect flowers that are able to be self-one self-pollinated. However, some of the grape cultivars can be incompatible to each other. So, before planning for making suitable hybrids, study of compatibility and incompatibility’s of pollinizers with maternal parents is necessary. Propose of this study is investigation of the compatibility and the effect of pollinizers include ‛Bidaneh Ghermez, ‛Bidaneh Sefidand Perlette on fruit set and quantitative and qualitative characteristics of cultivar Rish Baba Sefid in vineyard conditions. Therefore, pistils of cv. Rish Baba Sefid were emasculated (863 pistils in 9 clusters) and then were pollinated with pollen of Bidaneh Ghermez, Bidaneh Sefidand Perlette. Experiment was carried out based on completely randomized design (CRD). Ultimately of 91 obtained hybrid seed, in each cross with pollinizer cultivars of Bidaneh Ghermez, Bidaneh Sefid and Perlette were 52, 36 and 3, respectively. The results from these crossing showed that compatibility between pollen of cv. Bidaneh Sefid and cv. Rish Baba Sefid were more than other treatments but pollen of cv. Bidaneh Ghermezand cv. Rish Baba Sefid with 20% for seed forming if the this mount were nearest to self-pollinated. Two other treatments Bidaneh Sefidand Perlette with Rish Baba Sefid had 11.5% and 2.34%, seed forming respectively. Study of obtained fruits physical properties like fruit cluster weight, berry size and TSS/TA proved the advantage of pollen of cv. Bidaneh Ghermez hybrids.
