Drought And Heat Tolerance In Bread Wheat Landraces

By Sarah McLaughlin

Climate change is predicted to cause losses of more than 20% in agricultural production by 2050. With a growing global population, crops adapted to the effects of climate change, such as drought and heat, are necessary for the maintenance of productivity levels to meet the demand for food.

Scientists from the International Maize and Wheat Improvement Center (CIMMYT), in collaboration with scientists from the Universidad Autónoma Agraria Antonio Narro, set out to analyze bread wheat landrace traits against seven climactic variables: mean temperature, maximum temperature, precipitation, precipitation seasonality, heat index of mean temperature, heat index of maximum temperature, and drought index. 

Based on a sample of 990 bread wheat landraces from the CIMMYT genebank, the study discovered proteins associated with tolerance to drought and heat. With these results, new genotypes with resistant alleles can be selected for breeding programs to produce resistant varieties adapted to extreme environments and the effects of climate change.

Are your crops protected "right off the hop" this spring?

of AgronomyTV, we talk with John Gavloski, provincial entomologist with Manitoba Agriculture, out in Carman, Man. John breaks down exactly what insects growers should be scouting for as seeding gets underway, how to identify early-season crop damage, and when your seed treatments will start to wear off.

We cover key pests affecting canola, cereals, pulse crops, and alfalfa, including critical scouting windows and remedial management strategies.
