Abstract The change in the proteolytic activity of the seeds of the cotton plant varieties Tashkent-1- Tashkent-6, S-4727, and 108-F when the plants are affected by wilt has been studied. A relationship has been established between the decrease in activity for seeds of the Tashkent-1 and Tashkent-6 varieties and the degree of attack by wilt. A hypothesis has been put forward on the existence of variety differences in the response reaction of the cotton plant to the introduction of the pathogen. The appearance of distinctive electrophoretic protein components in the seeds of wilt-affected cotton plants of the Tashkent-1 and Tashkent-6 varieties has been shown. A hypothesis has been made of a possible increase in the amount of proteinase inhibitors in response to the infection of the plants by wilt, a consequence of which is a sharp decrease in proteolytic activity and the appearance of distinctive electrophoretic components.
