In: Smith, S., Diers, B., Specht, J., Carver, B., editors. Yield gains in major U.S. field crops. CSSA Special Publications 33. Madison, WI: American Society of Agronomy, Inc., Crop Science Society of America, Inc., and Soil Science Society of America, Inc. p. 53-86. Interpretive Summary: Yield of all crops have increased during the past century through improved cultural practices and plant breeding. We reviewed gains in yield of lettuce and spinach in the U.S., principally California and Arizona. We proposed several genetic models for yield of lettuce based on the market type: whole head, bulk, and baby leaf. This review provides a basis for controlled studies to partition yield increases of these crops into cultural and genetic components.
