| Abstract: |
| 【Objective】To carry out cross breeding of high-quality Hybrid Cymbidium by using Hybrid Cymbidium
germplasm resources, observe the performance of main target traits of offspring, and obtain new Hybrid Cymbidium varieties that
meet the requirements of target traits.【Method】With Cymbidium sinense Yunv and C. lancifolium Wen Yin-1 as parents,
conventional hybridization and seed culture of Hybrid Cymbidium were carried out. The characters of hybrid offspring were
investigated and analyzed, and compared with their parents and control varieties Moye Amethyst.【Result】A new excellent Hybrid Cymbidium variety Yuqinglan was bred through the mixed selection breeding program. The collective hybrid was registered
in the British Royal Horticultural Society under the name of Cymbidium SCAU Love Song. The results of variety comparison and
many years of multi-point experiments show that Yuqinglan has compact plant type, erect leaves, erect inflorescences, 9.5 flowers
on average, yellow white flowers with light fragrance, 5.6 cm in horizontal diameter and 5.9 cm in vertical diameter. It is cultivated
in simple greenhouses in Guangzhou, and starts to flower in late December. Its single flower life is 30 days, and its ornamental
period is 50 days. It is different from its parents in plant type, leaf type, and flower type, and its ornamental period is better than
their parents, and it is more ornamental and disease resistant than the control Moye Amethyst, and it also has the characteristics
of continuous flowering and forming flower lateral branches, which is the first report on orchids.【Conclusion】The new excellent
Hybrid Cymbidium variety Yuqinglan, which has been bred through cross breeding and innovative improvement methods, has good
characters and strong ornamental ability, and has broad prospects for popularization and application. |
