Effects of the resistance of nectariless and smooth leaf cotton on bollworms and its utilization


China Cottons (3): 46-47
Effects of the resistance of nectariless and smooth leaf cotton on bollworms and its utilization
Cage and field experiments in 1982-86 on 100 accessions of cotton, including nectariless + smooth leaf, nectariless + hairy leaf, and nectaried + hairy leaf cultivars or lines, showed that the nectariless + smooth leaf materials reduced the egg-mass of Heliothis armigera by 52.5-78.7% in cage tests and by 45.9 +or- 19.0% in the field. Nectariless + hairy leaf materials decreased egg-mass by 33.4% +or- 27.3% in the field.
