Abstract

The invention discloses a method and device for constructing Cynodon dactylon core germplasms with morphological markers. The method comprises the following steps: using original germplasms of Cynodondactylon as test materials, detecting 11 morphological traits through morphological marking, and selecting the best strategy to construct Cynodon dactylon core germplasms from 5 levels, including 7 kinds of total sampling proportion, 3 kinds of sampling methods, 5 kinds of clustering methods, 3 kinds of genetic distance, and 3 kinds of in-group sampling proportion. According to the embodiments ofthe invention, the constructed Cynodon dactylon core germplasms can effectively retain the phenotype genetic diversity, phenotypic trait correlation and population phenotype structure of the originalgermplasms and can be used as representative samples of a whole resource.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method and a device for constructing bermudagrass core germplasm using morphological markers. Background technique [0002] Bermudagrass (Cynodon Richard) belongs to the C4 type perennial herb of the Poaceae Teffaceae Sansevieria family. It is one of the three warm-season turfgrasses in the world and is also an excellent pasture grass (Harlan, 1969). Bermudagrass is divided into 9 species and 10 varieties (Taliaferro, 1995). Most bermudagrass originated in Africa, mainly distributed in warm and humid tropical or subtropical regions, and some bermudagrass are distributed in temperate regions (Rochecouste, 1962; Wofford and Baltensperger, 1985; Harlan, 1970). Among them, common bermudagrass (C.var.dactylon) is a widely distributed species in the world, with a horizontal distribution range of 53°N to 45°S; vertical distribution, it can grow not only below sea level but also on ...
