Effect of Spraying Benzyladenine and Male Parent on Hybrid Embryos Rescue in Grape (Vitis vinifera L.) cv. Askari

Grapevine is one of the most important fruit crops in the world. Seedless grapes are a type of grapevine that is preferred by most fruit consumers. Seedless grapevines are induced via either stenospermocarpy or parthenocarpy. Grapevine is one of important fruit crops with abundant nutrition materials that utilized by consumers from past. Breeding of seedless grapes is one of the important aim of breeders. Embryo rescue technique can provide new seedless grapes with desirable characteristics. In this study the effect of sprays with benzyladenine and male parent on embryo germination in Askari × Bidane Sefid and Askari × Bidane Ghermez crosses was investigated. Results showed that benzyladenine sprays and interaction between benzyladenine and male parent had significant effect on embryo germination, as highest germination was observed in Askari × Bidane Sefid cross (5.26%) that treated with benzyladenine. Interaction between benzyladenine sprays and male parent also had significant effect on callused, collapsed and enlarged ovules.
