Abstract

The invention belongs to the technical field of turf grass breeding, in particular to a breeding method of a novel variety of dwarf bermudagrass. The breeding method is characterized in that a bermudagrass seed is mutated through radiation and screened in a field, molecule marking and isozyme identification are adopted to assist the selection and the breeding, and the novel variety of the dwarf bermudagrass required by the market is bred. The radiation source of the invention is a universal 60Co-gamma ray, the dose thereof is 200Gy to 500Gy, and the dose rate is 1.0Gy / min. The bred novel variety of the bermudagrass has significant dwarf characteristics and good stay green, and the turf grown from the new variety of the bred dwarf bermudagrass is essentially free of trimming during a growth period.

Description

technical field The invention belongs to the technical field of turfgrass breeding, and in particular relates to a method for cultivating a new variety of dwarf bermudagrass turfgrass. technical background Bermudagrass (Cynodon dactylon (L.) Pers.) is also known as tripping root grass, climbing root grass, Bermuda grass, etc. It is a perennial warm-season turfgrass of the grass family Bermudagrass. Native to Africa, widely distributed in tropical, subtropical and warm regions. There are wild species all over the south of the Yellow River Basin in my country. It is the main turfgrass species for laying ornamental turf, sports turf and leisure turf in the middle and lower reaches of the Yangtze River and its south. Most of the bermudagrass varieties currently used to build lawns have the characteristics of fast growth of erect stems. In the maintenance of lawns, especially in the maintenance of sports field lawns, the frequent pruning times make the maintenance cost high. A...
