Research Team of Ornamental Plant Genetics and Breeding
in Shenyang Agricultural University
The team consists of five researchers, all of whom have PhD, including one professor, one associate professor and three lecturers. There are 600 m2 special laboratory, 10 mu experimental base and two greenhouses. It mainly engages in the collection, conservation, evaluation and utilization of germplasm resources, the inheritance of main characters, distant cross breeding, polyploid breeding, biotechnology and tissue culture on the ornamental plants, such as lily, iris, tulip, gentleman orchid and ornamental strawberry. We have presided over more than 50 projects of the Ministry of Science and Technology, the Ministry of Education, provinces and municipalities, among which three projects were the National Natural Science Foundation. More than 300 articles have been published, in which about 40 articles were published in SCI and ISTP, some books have been edited as editor-in-chiefs, such as Liaoning Flowers, and Greenhouse Cultivation of Main Fresh Cut Flowers in North China. There were 8 new lily cultivars, 4 new ornamental strawberry cultivars and 35 new iris cultivars released. More than 100 doctors and masters have been graduated and obtained their degrees.
Team leader Professor Lei Jiajun, postdoctoral student in Japan, now is the leader of ornamental horticulture discipline in Shenyang Agricultural University. He is also a council member of China Flower Association, the executive director of Bulbous Flower Branch, Chinese Society for Horticultural Science, the executive director of Liaoning Horticultural Society, the member of Chinese Tulip Expert Committee, the vice director of Liaoning Flower Association and the vice director of Shenyang Flower Association. The team also includes associate professor Bi Xiaoying, lecturer Zheng Yang, lecturer Zhao Jun, and lecturer Xue Li.
The main research directions of this team are as follows.
Research and utilization of Lilium germplasm resources: 350 lily germplasm resources were collected and preserved, and their genetic diversity, chromosomes, pollen, distant hybridization, in vitro conservation and embryo rescue techniques were systematically studied. A large number of distant hybridization progenies were obtained, and new lily cultivars such as diploid, triploid, tetraploid and pollen-free were cultivated. In 2016, the first National Lily Germplasm Bank was approved in China.
Research and utilization of Iris germplasm resources: More than 100 Iris germplasm resources have been collected and preserved. Research work has been carried out on genetic diversity, chromosome, pollen, seed dormancy, germination characteristics, distant hybridization, flower color inheritance, etc. A large number of new materials for distant hybridization have been obtained, and iris cultivar has been first internationally registered in China.
Research and utilization of Tulip germplasm resources: 80 tulip resources were collected and preserved. The genetic diversity, chromosome, karyotype, pollen, seed dormancy, polyploid breeding and in vitro culture were studied.
Research and utilization of Clivia germplasm resources: At present, 60 Clivia germplasm resources were collected. The distant hybridization, chromosome doubling, in vitro culture, flower bud differentiation and flowering regulation were systematically studied. There are large-scale cooperative bases in Anshan, Liaoyang and Shenyang.
Fragaria germplasm resources and ornamental strawberry breeding: 620 strawberry resources were collected and preserved in Shenyang Agricultural University, which was one of the richest germplasm in the world. Great progress has been made in classification, evaluation, distant hybridization, chromosome doubling, polyploidy, ornamental strawberry germplasm innovation and so on.
