摘要

Flax is an important agricultural crop grown for oil and fiber. Flax fiber is used in various industries and breeding new flax varieties with better fiber characteristics is subject of interest. Genome-wide association studies (GWAS) can find variants associated with traits important for fiber quality, but differences in data due to different growing conditions in different years reduce the power of GWAS methods. The 3VmrMLM method allows one to search for variants in data measured in several environments, allowing one to find new variants not found by other methods. Measurements in different years were taken as different environments; the method found a total of 205 variants characteristic of all or several environments, 37 of which were located in the body of known genes with important functions; the effect of some variants on fiber characteristics was also confirmed in an independent set of plants.
