Pink Bollworm Resistance and Lint Yield of a Nectariless, Okra-Leaf Germplasm Line
A nectariless, okra -leaf germplasm line of cotton, Gossvpium hirsutum L., designated WC-12NL, was compared with a nectaried, regular leaf commercial cultivar, 'Deltapine 61' (DPL-61) at two locations, Maricopa, AZ and Brawley, CA. At Maricopa, two and three insecticide applications were r...

| Summary: | A nectariless, okra -leaf germplasm line of cotton, Gossvpium hirsutum L., designated WC-12NL, was compared with a nectaried, regular leaf commercial cultivar, 'Deltapine 61' (DPL-61) at two locations, Maricopa, AZ and Brawley, CA. At Maricopa, two and three insecticide applications were required for control of pink bollworm, Pectinophora gossypiella (Saunders), on WC-12NL and DPL-61, respectively. At Brawley, six and nine applications were required. Lint yield of WC-12NL was 30% higher than that of DPL-61 at Maricopa, while at Brawley, lint yields were about equal. |
