Horticultural scientists tend plant breeding trials aimed at developing improved crop varieties.
Breeding programs for major agricultural crop species are capable of meeting adaptation needs associated with climate change. Breeding programs for many regionally important, specialty, and /or perennial crop species may face greater challenges.
Will significant adjustments at the regional scale of agricultural production be required because of CO2-driven climate change?
Analyses of potential influences of climate change on agricultural ecosystems typically ignore regionally important specialty crops that may be especially sensitive to geographic shifts in climate.
Impacts of climate change on agriculture will vary from crop to crop, location to location, and system to system. Adaptation may be constrained by factors other than climate and crop genetic capability, including availability of suitable soils and adequate supplies of water.
