Response of Nectaried and Nectariless Pima Cotton to Pink Bollworm
MetadataShow full item record
AbstractFour Pima cotton entries were grown in large plots at MAC, not treated with insecticide, to determine their response to attack of pink bollworm. P62, an early -maturing germplasm line, sustained significantly less seed damage caused by pink bollworm than did 'Pima S-6', Pima S-6 nectariless, and P62 nectariless. The nectariless trait did not reduce seed damage significantly.
