Abstract

Cotton lines (Gossypium hirsutum L.) possessing the okra leaf (L°L°) — frego bract (fg fg) characters were evaluated in a 3-year field study in the Coastal Bend area of Texas. Two locations were used in 1974 and 1975 and one location in 1976. The number of squares (flower buds) with boll weevil (Anthonomus grandis Boheman) ovipositional punctures was recorded on a total of forty cotton lines.

Cotton lines possessing the okra leaf-frego bract characters averaged about 60% fewer boll weevil ovipositional punctured squares than the broad leaf — normal bract cottons.
