✦ Synopsis

Breeding of herbicide-resistant foxtail millet (Setaria italica (L.) Beauv.) is desirable in modern agriculture because no selective herbicide is available for this crop. TriÑuralin-resistant millet lines obtained from a interspeciÐc cross between a resistant green foxtail (Setaria viridis (L.) Beauv.) and a foxtail millet cultivar were tested for response to Ðve dinitroaniline herbicides in greenhouse and Ðeld experiments. The results in the greenhouse study showed that the resistant type was cross-resistant to all tested herbicides. values indicated that ED 50 the highest resistance was obtained with triÑuralin, the resistant biotype being seven and 33 times more resistant than the parent cultivar at the emergence and seedling stages, respectively. However, the doses recommended for efficient weed control resulted in some detrimental e †ects on emergence and growth in the Ðeld. Strategies for use of this resistance to control weeds in millet Ðelds are proposed.
