Ploidy identification is one of the basic tasks for germplasm resources and new variety breeding of tropical flowers. In this study, flow cytometry was used to identify the ploidy level of Cymbidium hybrid seedlings. aiming at the key links such as the type of dissociated liquid, the tissue organ of the test material, evaluation indexes such as the nuclear dissociation, the clear degree of the main peak, the easy degree of sampling, and the coefficient of variation. A technique system was established and the stomatal traits of different ploidy were analyzed. The results showed that CyStain UV Precise P was the best of the three dissociated liquid and young leaves were most suitable. Six triploid and two tetraploid were identified from the offspring of the three hybrid combinations. There were significant differences in stomatal length, width and density between different ploidy (P<0.05). The rank of stomatal length and stomatal width was tetraploid>triploid>diploid, while stomatal density was reversed. This study is valuable for the polyploid selection and use of different ploidy germplasm resources for cross breeding of Cymbidium hybrid.

倍性鉴定是热带花卉种质资源鉴定及新品种选育的基础工作之一。本研究利用流式细胞仪对兰属杂交后代进行倍性鉴定。针对裂解液种类、试验材料组织器官等关键环节,以细胞核解离情况、主峰清晰程度、变异系数及取材容易程度等方面为评价指标,建立鉴定体系,并比较不同倍性植株的气孔性状差异。结果表明:CyStain UV Precise P为3种裂解液中最优,组织器官以嫩叶为宜;从3个杂交组合后代中鉴定出三倍体6株,四倍体2株,不同倍性间的气孔长度、宽度和密度均差异显著(P<0.05),气孔长度和宽度的排序为四倍体>三倍体>二倍体,而气孔密度的排序则相反。该研究结果对杂交兰多倍体选育及开展不同倍性间杂交育种具有重要应用价值。

倍性鉴定是热带花卉种质资源鉴定及新品种选育的基础工作之一。本研究利用流式细胞仪对兰属杂交后代进行倍性鉴定。针对裂解液种类、试验材料组织器官等关键环节,以细胞核解离情况、主峰清晰程度、变异系数及取材容易程度等方面为评价指标,建立鉴定体系,并比较不同倍性植株的气孔性状差异。结果表明:CyStain UV Precise P为3种裂解液中最优,组织器官以嫩叶为宜;从3个杂交组合后代中鉴定出三倍体6株,四倍体2株,不同倍性间的气孔长度、宽度和密度均差异显著(P<0.05),气孔长度和宽度的排序为四倍体>三倍体>二倍体,而气孔密度的排序则相反。该研究结果对杂交兰多倍体选育及开展不同倍性间杂交育种具有重要应用价值。

Ploidy identification is one of the basic tasks for germplasm resources and new variety breeding of tropical flowers. In this study, flow cytometry was used to identify the ploidy level of Cymbidium hybrid seedlings. aiming at the key links such as the type of dissociated liquid, the tissue organ of the test material, evaluation indexes such as the nuclear dissociation, the clear degree of the main peak, the easy degree of sampling, and the coefficient of variation. A technique system was established and the stomatal traits of different ploidy were analyzed. The results showed that CyStain UV Precise P was the best of the three dissociated liquid and young leaves were most suitable. Six triploid and two tetraploid were identified from the offspring of the three hybrid combinations. There were significant differences in stomatal length, width and density between different ploidy (P<0.05). The rank of stomatal length and stomatal width was tetraploid>triploid>diploid, while stomatal density was reversed. This study is valuable for the polyploid selection and use of different ploidy germplasm resources for cross breeding of Cymbidium hybrid.
