Abstract
The resistance of several strains of cotton to the boll weevil, Anthonomus grandis Boheman, was studied for 4 years at Stoneville, Mississippi. Strains included were M-8, D2-Smooth, Pilose-Okra leaf, Nectariless, Glandless, Yugoslav-Early Upland, Red Plant, and Asiatic. The Asiatic strain was significantly more resistant than any of the others. Yugoslav Early had the earliest and greatest boll weevil infestation.D2-Smooth, Glandless, and Nectariless had intermediate infestations, all of the same level. Plant height, color, and growth characteristics were factors affecting the percentage of squares punctured.
