Note: Groups G1 and G2 were classified based on the results of STRUCTURE analysis of the 158 cotton lines.

The G1 group were further partitioned into G1a, G1b and G1c subgroups, and the G2 group into G2a, G2b, G2c and G2d subgroups.

The intermediates in the total panel, G1 group and G2 group were named as “Mixed”, “G1 mixed” and “G2 mixed”, respectively.
