Résumé
Several cotton Gossypium hirsutum L. race stocks have been identified that possess resistance to the boll weevil Anthonomus grandis Boh. because oviposition in the bud is decreased. In three tests of 13 boll weevil resistant lines conducted over a 6 year period on average, boll weevil punctures were decreased by 37.2% as compared to two susceptible commercial lines, while anther sugars were decreased 34.3% and anther gossypol was decreased 19.6%. Sugars and gossypol in the petals and ovaries were not different, however. Gas-liquid chromatographic analyses via the alditol acetate procedure revealed that the major free sugars of both the boll weevil suppressant and commercial cotton lines were glucose, fructose, sucrose, and arabinose with lesser amounts of xylose, galactose, and erythritol. Efforts to incorporate genes for oviposition resistance into commercial lines based on their correlation with low anther sugar content may have some promise.
