In recent years a number of glandless cotton varieties has been developed in China. Assessment of their economical values is based on the results of an overall analysis of fibre quality and seed quality. Quality analysis indicates that the theoretical yield of glandless variety is higher than that of the glanded variety (control). But its actual yield is lower due to boll rot and other reasons. This fact is worthy of attention of producers in a rainy area. Its fibre quality is comparable to that of the glanded variety, but it is noted for a greater ecological variability. The purity of gossypol in a glandless variety and its extraction are still problems remaining to be solved. A high negative correlation exists between the protein content and fat content of a seed kernel. It is possible to develop a glandless variety rich in protein, but a new germplasm must be sought in order to breed a variety of high lysine content
