Identification of Isogenic ‘Naked-Tufted’ Seed Coat Mutants in Cotton

Abstract

A stable isogenic line with ‘naked-tufted’ seed has been identified in the restorer line AKH 98-81 through mass selection process. The original genotype was fuzzy with the dense white fuzz throughout the seed surface. The isogenic line is naked and has a small tuft of hair only at the micropylar region. Such genotypes with naked seeds will help in avoiding acid delinting of seeds, which is done at the time of sowing, for easier separation of seeds. This character will also help in reducing seed coat neps and reducing short fibre content.
