Abstract:

16 major domestic flax varieties and superior strains were used as experiment materials and Jinya 10 as the control in our study to evaluate nine main agronomic traits including plant height, processing length and the number of stem under natural drought and normal irrigation in Datong. The drought resistance of the species was compared by calculating the drought resistance coefficient combined with linolenic acid, oil content, the subordinate function value and the drought resistance comprehensive evaluation values (D value). According to the D value, the drought-resistant adaptability of the species was evaluated and grouped into three categories. In conclusion, the varieties with strong adaptability to drought were selected out: 2075-20, Jizhangya 1, 423, 24005-8, Yiya 6, 9718, Neiya 9, Nei 44, Baxuan 3 and Longya 10 as recommended flax varieties to be planted in Datong region of Shanxi.

Key words: Flax, Drought resisant adaptability, Subordinate function, Cluster analysis
