Brief Introduction of Research Team of Lily in Beijing University of Agriculture
Research and Development Team of Lily belongs to Landscape Architecture, Beijing University of Agriculture. It currently employs a total of 9 faculties, including 5 professors, 2 associate professors, 2 senior technicians and 12 MSc graduate students. Since the end of 1980s, the research team focused on collection, cultivation, reproduction and innovation of lily germplasm, postharvest storage and fresh-keeping research. It owns Research and Innovation Base in Beijing University of Agriculture, and cooperates with several companies, including Yunnan Yuxi Pearl Flower Co., Ltd., M•Grass and Beijing Jinhe Horticulture Technology Co., Ltd. to tackled key problems in breeding of new lily varieties.
Beijing University of Agriculture carried out lily research from many aspects long ago. We will summarize our achievements in the following six aspects: lily resource collection and introduction experiment, lily basic biological characteristics research, lily industrialization key technology research, lily breeding research, lily molecular biology research, lily fragrance research and so on.
Lily resource collection and introduction experiment
Professor Xiangyun Zhao of Beijing University of Agriculture began collecting and introducing lily germplasm in the late 1980s. She made many field investigations on the distribution of lilies in Northwest, Southwest and Northeast China. More than 30 Lilium species and about 500 Lilium varieties were collected and introduced from home and abroad for different purposes. According to the target of lily breeding, we selected core planting resources and preserved about 100 Lilium species and varieties. Four books and 13 articles have been published in the field.
Lily basic biological characteristics research
Researches on anatomy, embryology, physiology and cell biology were carried out to understand the structure of vegetative organs, including lily root, stem and leave, the substance in bulb during lily storage, the type and content of petal pigments and the embryonic development process. We also founded the method of chromosome ploidy identification. Seven research papers have been published in this field.
Lily industrialization key technology research
Aiming at the problems in lily production process, the key industrialization technologies such as virus-free tissue culture and rapid propagation, virus detection, scales cutting and bulb degeneration were studied. In 2005, ‘A Rapid Culture Method for Virus-free Lily bulb’ was authorized by the State for invention patent. Eleven papers have been published in this field.
Lily breeding research
The team carried out germplasm resources innovation by radiation technology earlier. Lily cross breeding was carried out in recent 10 years. From the perspective of resource utilization, the pollen vigor, compatibility of cross combinations, methods of overcoming incompatibility before and after fertilization, embryo rescue and authenticity identification of hybrid were studied. From 2000 to 2015, 24 new lily varieties for courtyard cultivation were cultivated, and all of them were registered in the Royal Horticultural Society (RHS). Among them, four new varieties for garden cultivation, 'Red Yunjing', 'Yundanbaobei', 'Elegant Prince' and 'Fenjiaren', were identified by Beijing Municipal Forest Variety Examination and Approval Committee. In the field 17 papers have been published. (see Certificate for details)
Lily molecular biology research
In recent years, combined with the cultivation of postgraduate students, molecular biology research on lily has been carried out, including the construction of lily regeneration system, anti-virus and anti-bacteria genes cloning, color formation mechanism and so on. In the research field we have published 10 papers.
Lily fragrance research
In recent years, the Professor Pingsheng Leng from Beijing University of Agriculture has made good use of all kinds of lily resources, which we have collected, to study the regularity and mechanism of lily fragrance release, achieved good results and published 8 papers on lily flower fragrance.
Research and Development Team of Lily in Beijing University of Agriculture has been insisting on the combination of production, teaching and research. Besides researches, it has also devoted all its efforts to the development and application of lily industry in Beijing mountainous areas. Combining with the teaching and scientific research work of the university, we have successively established the demonstration base of lily domesticated seedballs in Sihai, Zhangshanying and DazhuangkeSihai towns of Yanqing distict, Shangzhuang town of Miyun distict and other mountainous villages and towns. We have gone deep into the rural base all the year round, regardless of winter or summer, without pay or holidays, summarized the key technologies in the localized production of lily, and vigorously propagated and popularized the new varieties and new technologies of lily, and promoted the development of lily production in Yanqing, Huairou, Miyun, Pinggu and Changping districts. We have formulated ‘National Lily Fresh Cut Flower Cultivation Technical Rule’ of the Ministry of Forestry, and approved ‘Beijing Lily Cut Flower Production Technical Rule’ and ‘Seed Ball Production Technical Rule’, and trained more than 300 technical backbones for lily production in Beijing. ‘Rapid cultivation technology of lily virus-free seed balls’ and ‘Cultivation techniques suitable for lily bulb propagation and growth in cold mountain areas at high altitude’ have also been popularized to lily bulb production areas in southwest and northwest China. Research and Development Team of Lily in Beijing University of Agriculture has made due contributions to the development of lily industry in China.
