Major global crops in high-yielding, temperate cropping regions are facing increasing
threats from the impact of climate change, particularly from drought and heat at critical …

This chapter reviews four main aspects of genetic diversity in soybean: formation, collection,
evaluation, and utilization. Because the benefit of genetic diversity can be realized only by …

This new edition of a bestseller examines plant nutrition's role as one of the most important
limiting factors that must be overcome to optimize food production. Extensively revised and …

Soybean improvement via plant breeding has been critical for the success of the crop. The
objective of this study was to quantify genetic change in yield and other traits that occurred …

Increasing yield is a high priority in most breeding programs. Approximately 600 soybean
cultivars had been released by the end of the last century in Northeast China …

One of the main approaches for safeguarding food security, sustainable development has
increased demand for knowledge on fertilizer management in crop production. Among …

Soybean [Glycine max (L.) Merr.] yield has increased during the past century; however, little
is understood about the morphological parameters that have contributed most to yield gain …

Pod and seed number are the most important yield components of soybean [Glycine max
(L.) Merr.]. Leaf area index (LAI), leaf area duration (LAD) and dry matter accumulation …

Summary Soybean [Glycine max (L.) Merr.] yield improvement arises from continual
producer adoption of genetic technology—the annual releases of new cultivars that express …

Yield increase in soybean [Glycine max (L.) Merr.] has occurred due to plant breeding, as
well as the improvement in management practices. Genetic gain for important traits in …
