To study the agronomic traits of generation introduced from wild flax, the basic statistics, principal component analysis, and cluster analysis of 26 agronomic traits obtained from 26 individual plants were performed through field experiments. The results showed that the number of capsules and seeds per plant in the progeny were the largest, followed by the stem thickness and the weight. According to the principal component analysis, the first main factor of the offspring introduced into the pollen tube is the lodging factor dominated by stem thickness and stem weight per plant. The cluster analysis showed that the 26 single plants received were divided into four categories, among which the first category appeared dwarfed and the fourth category appeared super-parent.
