Abstract

The primary aim of seed companies is to provide products that the customer wants to buy, and to sell them at a profit. Future demands for improved cultivars of major field crops will continue to be primarily for those with reliably high yield and desirable quality. Herbicide tolerance will not be a primary determinant in cultivar choice for most customers. Therefore, seed companies probably will move with caution in development of herbicide-tolerant cultivars.
