Physiological Basis of Successful Breeding Strategies for Maize Grain Yield

During the maize (Zea mays L.) hybrid era (1939 to present), commercial grain yields have improved nearly sixfold and the genetic component of the improvement has been estimated as approximately 60%. In this paper, we examine physiological factors and successful breeding strategies that underlie the...
