Natural Resistance to Thrips Injury in Cotton as Measured by Differential Leaf Area Reduction¹

Ten entries of cotton (Gossypium hirsutum L.) were evaluated for 2 years to measure their relative resistance to injury from thrips (Thripidae). Resistance was measured as the percentage of leaf area reduction associated with thrips damage. Leaf area was determined three times at weekly intervals during each year.

Pilose (H₂) was associated with a high level of resistance to thrips. Other morphological traits such as Okra-leaf shape (L°), Red plant color (R₁), glandless (gl₂, gl₃), nectariless (ne₁, ne₂), or smooth leaf (Sm₁, Sm₂) did not provide the plant with resistance. Significantly less leaf area damage occurred on the pubescent ‘Tamcot SP-37’ cultivar than on the glabrous ‘Tamcot SP-21’ cultivar.

Key Words: Insect resistance • Pubescene • Glabrous • Isolines • Leaf area • Gossypium hirsutum L.
