Abstract: The need to accelerate breeding for increased yield potential and better adaptation to drought and other abiotic stresses is an issue of increasing urgency. As the population continues to grow rapidly, the pressure on resources (mainly untouched land and water) is also increasing, and potential climate change poses further challenges. We discuss ways to improve the efficiency of crop breeding through a better physiological understanding by both conventional and molecular methods. Thus the review highlights the physiological basis of crop yield and its response to stresses, with special emphasis on drought. This is not just because physiology forms the basis of proper phenotyping, one of the pillars of breeding, but because a full understanding of physiology is also needed, for example, to design the traits targeted by molecular breeding approaches such as marker-assisted selection (MAS) or plant transformation or the way these traits are evaluated. Most of the information in this review deals with cereals...

Crops that feed the world 6. Past successes and future challenges to the role played by maize in global food security
TL;DR: In this paper, the Green Revolution (GR) has played an outstanding role in feeding a hungry world and improving global food security, and it also generated its own environmental problems also productivity increase is now slow or static, and achieving the productivity gains needed to ensure food security will therefore require more than a repeat performance of the GR of the past, while the key challenges today is to replace these varieties with new ones for better sustainability.
Nonlinear heat effects on African maize as evidenced by historical yield trials
TL;DR: In this article, an analysis of over 20,000 historical African maize trials suggests the crop will better cope with climate change under rain-fed management, and that optimal rainfed conditions would mean 65% of maize-growing areas in Africa would be likely to experience yield losses, compared with 100% under drought conditions.

General mechanisms of drought response and their application in drought resistance improvement in plants
TL;DR: With increasing knowledge to comprehensively decipher the complicated mechanisms of drought resistance in model plants, it still remains an enormous challenge to develop water-saving and drought-resistant crops to cope with the water shortage and increasing demand for food production in the future.

TL;DR: A functional genomics approach has identified a transcription factor from the nuclear factor Y ( NF-Y) family, AtNF-YB1, which acts through a previously undescribed mechanism to confer improved performance in Arabidopsis under drought conditions and has the potential to significantly impact maize production systems that experience drought.

Post–Green Revolution Trends in Yield Potential of Temperate Maize in the North-Central United States
D. N. Duvick,Kenneth G. Cassman +1 more
TL;DR: There is conflicting evidence to support the hypothesis that maize yield potential has increased since the advent of the “Green Revolution” that began in the late 1960s, according to evaluation of maize breeding efforts, changes in plant traits of commercial hybrids, and by comparison of statewide average yield trends and yield trends in sanctioned yield contests.
Yield potential, yield stability and stress tolerance in maize
TL;DR: Stability analyses were performed on a number of high-yielding maize hybrids, including three hybrids that have been involved in some of the highest maize yields recorded in producers’ fields, to examine the relationship between yield and yield stability.
