Study on breeding polyploidy grape by embryo rescue techniques
Abstract：For the purpose of breeding triploid grape, five cross combinations including Ruby Seedless （Vitis vinifera） x Fujiminori （V. vinifera x V. labrusca）, Dawn Seedless （V. vinifera） x Fujiminor （V. viniferax V. labrusca）, Emerald Seedless （V. vinifera） x Black Olimpia （V. vinifera x V. labrusca） , Fu- jiminori x Beichun （V. vinifera x V. amurensis ）and Black Olimpia x Beichun were performed and embryo rescue techniques were employed. As a result, 41 hybrid seedlings were obtained. Furthermore, the chro- mosome ploidy of these hybrids was measured by flow cytometry and chromosome identification. The re- sults showed that the hybrids were made up of 10 triploid plants, 6 tetraploid plants, 4 aneuploid plants and 21 diploid plants. This study will provide a foundation for further breeding triploid varieties and new breeding materials in grape.
