Embodiment Construction

[0019] (1) Breeding method

[0020] Sheyang County, Jiangsu Province is one of the main producing areas of white chrysanthemums in my country. It has been cultivated for nearly 50 years. Many years of planting have made chrysanthemum diseases worse every year, especially silkworm and wilt. The reason for this problem is It is mainly multi-year continuous cropping. Almost all the land in the town is chrysanthemum cropping land, and 10% to 20% of the land can no longer be planted with chrysanthemums, and other plots are also increasing year by year. Nanjing Agricultural University selected and bred medicinal chrysanthemum disease-resistant varieties. The petals of the local cultivar New White Chrysanthemum were used as explants, and the disease-resistant cell lines induced by chrysanthemum chrysanthemum and Fusarium wilt virus were used to cultivate test-tube plantlets, and then the Planted in Yanmar Town. Cultivated for two consecutive years to investigate the incidence of bact...

Abstract

The invention discloses a breeding method for a southern blight-resistant and wilt of dendranthema morifolium. The breeding method comprises the steps of selecting the variety, cultivating the resistance, breeding cutting seedlings, breeding the stability and the consistency of a property, conducting a variety comparison test, a production test and disease statistics for continuous two years, and determining the disease-resistant variety NJK-1 of the dendranthema morifolium with the property. The breeding method has the advantages that a research is conducted by screening the disease-resistant variety as an object and integrating indexes such as a yield, the inherent quality and the property of the dendranthema morifolium, so that the disease-resistant variety of the dendranthema morifolium, which is stable in property and good in quality is cultivated; the disease resistance is improved and plant diseases and insect pests are reduced, so that the yield of the dendranthema morifolium is at least increased by 44%, the production costs of an agent for preventing and treating the diseases, manual work and the like are saved greatly, and very good economic and social benefits are generated; the application amount of a pesticide is reduced, so that secondary pollution to an environment is reduced, and a chronic injury to human health is reduced; and the breeding method is convenient to operate, simple, easy, and easy to achieve.
