Preliminary study on Populus euphratica Oliv. hybridization and breeding.

【Objective】The main purpose of this study was to reveal the key method for hybridizing Populus euphratica Oliv.and Leuce Duby,Tacamahaca Spach.,Aigeiros Duby,to obtian hybridized breeds with genetic characteristics of Populus euphratica Oliv.【Method】Using Populus euphratica Oliv.as female parents to hybridize with Sect.Leuce Duby,Sect.Tacamahaca Spach.,Sect.Aigeiros Duby,by bagging method,using Populus euphratica Oliv.as male parents to be hybridized with Sect.Leuce Duby,Sect.Tacamahaca Spach.,Sect.Aigeiros Duby,with water culture and cutting branches.The hybrid seedling were culture by nutrient cups.【Result】4 artificial hybridized seedling combinations were obtained using Populus euphratica Oliv.as female parents,3 artificial hybridized seedling combinations were obtained using Populus euphratica Oliv.as male parents. 【Conclusion】The order of each combination using Populus euphratica Oliv.as female parents and each combination using Populus euphratica Oliv.were as follows:The best was P.talassic×P.Euphratica,the followed by Sect.Tacamahaca Spach.and Sect.Aigeiros Duby,the worst is Section Leuce Duby.These results can be the fine foundation for Populus euphratica Oliv.meliorating in the future.
