本筛选研究通过对中国栽培的61个锦鸡品种的染色体数目进行统计，分析其倍性水平。在这些品种中有4个品种发现了三倍体：Populus x euramericana (Dode) Guiner cv。Wuhei-1, R x Liaohenica， P. Langfangensis-3 Wang （P. deltodide Barry等）。“山海关”x R simonii x R pyramidalis-12+Ulmus pumila Linn.)，和P. x euramericana (Dode) Guinier。简历。“Zhonglin-46”。核型分析表明，该三倍体可能是由原同种异体三倍体衍生而来。由于三倍体树木在我们收集材料的人工林中的生长速度快于它们各自的二倍体杂交种或无性系，我们期望它们在中国的育种、再造林和纤维生产中发挥重要作用。
This screening study analyzed ploidy levels by counting the chromosome number of 61 Aigeiros cultivars grown in China. Triploid Aigeiros has been found in four of these cultivars: Populus x euramericana (Dode) Guiner cv. Wuhei-1, R x Liaohenica, P. Langfangensis-3 Wang (P. deltodide Barry cv. "Shanhaiguan" x R simonii x R pyramidalis-12+Ulmus pumila Linn.), and P. x euramericana (Dode) Guinier. cv. "Zhonglin-46". The karyotype analysis indicates that triploid Aigeiros might be derived from original allotriploid. Because growth of the triploid trees was faster than their respective diploid hybrids or clones in the plantations where we collected the materials, we expect that they will play a significant role in breeding, reforestation and fiber production in China.
