Researchers try producing potato resistant to climate change

BANGOR, Maine – University of Maine researchers are trying to nutrient potatoes that tin amended withstand warming temperatures arsenic the clime changes.

Warming temperatures and an extended increasing play tin pb to prime problems and disease, Gregory Porter, a prof of harvest ecology and management, told the Bangor Daily News.

“The predictions for clime alteration are heavier rainfall events, and potatoes don’t tolerate flooding oregon bedewed conditions for agelong without having different prime problems,” Porter said. “If we privation potatoes to beryllium continued to beryllium produced successfully successful Maine, we request to beryllium capable to nutrient varieties that tin beryllium resistant to change.”

Around the world, probe aimed astatine mitigating harvest harm is underway. A NASA survey published this period suggests clime alteration whitethorn impact the accumulation of maize and wheat, reducing yields of both, arsenic soon arsenic 2030.

Maine is coming disconnected of a banner murphy harvest acknowledgment successful portion to the occurrence of the Caribou russet, which was developed by UMaine researchers. But Porter fears that adjacent that assortment isn’t arsenic vigor tolerant arsenic indispensable to defy the aboriginal effects of clime change.

Pests are different factor. The Colorado murphy beetle and disease-spreading aphids person flourished with the changing climate, said Jim Dill, pest absorption specializer astatine the University of Maine Cooperative Extension.

Breeding seemingly tiny changes similar hairier leaves that marque it hard for insects to determination astir connected the works tin chopped down connected pests’ demolition and besides the request for pesticides, helium said.

Breeding specified characteristics into potatoes is simply a agelong process of cross-pollinating antithetic murphy varieties.

The process is good underway.

They're successful a probe investigating signifier close present astatine sites passim the United States. Test potatoes successful Virginia, North Carolina and Florida are investigating precocious somesthesia stress.

“It takes 10 years of enactment aft that archetypal transverse pollination, and it mightiness instrumentality 2 to 5 years earlier capable commercialized valuation has taken spot to merchandise a caller murphy variety,” Porter said.
