Normal type and abnormal type of γ 2 generation of a cotton high-yied variety Emian 15 and a high yield cotton line 05①006, as well as their nonirradiated materials were investigated to study the correlations between six major economic traits such as lint yield, etc and nine agronomical traits such as plant hight.

Normal and abnormal type of γ 2 generation of a variety and a line with high yield, “Emian 15" and “05①006", as well as their non irradiated materials were made to study the correlation between six major Economic traits (lint yield, ect).
