✦ Synopsis

A method for screening populations of potato genotypes for sensitivity to metribuzin has been developed. Plants grown from both tubers and true seed were screened in the greenhouse by growing them in a metribuzin-containing nutrient solution. Sensitivity to metribuzin was found to be determined by a single recessive gene in several categories of cultivated diploid potatoes. The gene symbol me is proposed. The frequency of me in a population of Sohnum tuberosum Groups Phureja and Stenotomum was estimated at 0.7. The me gene is a potentially useful marker gene in potato genetics. Some implications of breeding for herbicide tolerance and the use of agricultural chemicals in germ plasm material are discussed.
