Selection, Cross Breeding And Cultivation Experiment Of Potted Large Spray Chrysanthemum Varieties

Potted large spray chrysanthemum (Chrysanthemum×morifolium Ramat.) is the improved type of traditional chrysanthemum with multiple branches, each branch of a plant has one or more flowers. The number of branch is different. There was another type that made a number strains in the same basin. The branch number was based on market demand and requirements. The potted large spray chrysanthemum was not only single basin ornamental decorations for indoors, but also can be used by a larger piece,and used in large-scale flower arrangement, it is good materials for festival flowers adornment.At present, the potted large spray chrysanthemum supply is also rare, but in other countries, potted large spray chrysanthemum has been put on sales schedule as a kind of fashion goods, this will become a development of the flower industry trends and new growth point. There were rich variety resources of traditional chrysanthemum in our country, which can be selected for large-scale production directly. In the meantime, we also need to cultivate new varieties by crossbreeding constantly to assure the flower enterprises can develop sustainable; Moreover, To establish appropriate cultivation techniques can truly put it into industrialization.Based on the above three, the author made a research on varieties breeding and industrialization cultivation technology, and get results as follows:(1) Through design the questionnaire and analyzed effective questionnaires, determined the potted large spray chrysanthemum's breeding objective is:branched, stalks strong. The best ornamental traits for plant should height below 50cm, in centimeters, much branched, has the best number of flower, flowering consistent, neatly composite, design and color of the flower is pure, large covering area of flowers, aroma, strong illness.(2)Comprehensive analyzed " The testing guidelines for distinctness, uniformity and stability of chrysanthemum of People's Republic of China "," Evaluation standard for standard chrysanthemum on chrysanthemum exhibition "and " Evaluation standard by hundred-mark system for standard chrysanthemum ", established "Evaluation standard by hundred-mark system for.potted large spray chrysanthemum" to evaluate potted large spray chrysanthemum.(3) The primary access to 34 species, get 5 by the check varieties, in the end, obtain 3 varieties,(4) Through the natural flowering of hybrid and out-season hybrid, screened 7 hybrid combination and 79 pairs of non-hybrid, access to seed 79;Explored the difference of crossbreeding technology on potted chrysanthemum at different seasons and hybrid technology of some special varieties.(5) Through cultivation experiment for the three varieties, established appropriate cultivation techniques. This technique can minimize labor and land costs; The tests were carried out for industrialized production potted chrysanthemum best flower number should between 3 and 5. The main technique factor to ornamental characteristics is the times of pinching.
