Abstract:

In order to utilize efficient 110 flax germplasm resources imported from the United States, ten main agronomic characteristics were analysed. The results showed that the genetic diversity indexes were 0.26 to 2.04, the variation coefficients were 13.85% to 90.79%. Correlation analysis and path analysis showed that the seed yield per plot forms highly significant positive correlation with tiller stem number, branching number, capsule number and seeds per plant, and the capsule number had the highest effect on the seed yield per plot, and had high direct effect and indirect effect. Through principal component analysis, the yield factor, fiber factor and ineffective factor were extracted, and the accumulating contribution rate was 72.796%. Through clustering analysis, the 110 flax germplasm were divided into six categories, among which the resource materials in categories IV, V, and VI had excellent agronomic traits and high utilization value.

Key words: Flax (Linum usitatissimum L.), Germplasm resources, Agronomic characteristics
