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.

If you assumed Nebraska was too hot and dry for white mold to be a problem in soybeans, think again.

This week we're featuring Galen Samuelson, a farmer and dealer from Wakefield, Nebraska, who knows all too well how devastating white mold can be.

"We don't have it consistently every year, but with our temperature and humidity, it can hurt us quite bad," Samuelson says. Looking for alternatives, he explains, "What I like about Heads Up is that it's non-harmful to the beneficial fungal colonies in the soil." Galen has been using Heads Up for several years now, after first hearing about it through a small ad in a regional newspaper. Watch below to hear about his journey.

When asked to write about Samuelson Seed, Galen said the following:

"Samuelson Seed is a 4th-generation, family-based company. It started with my grandfather, and I'm now starting to pass the torch to my son, Caleb."

"In the early 1990s, I started working with a company whose focus was on plant and soil health before those benefits were widely known. I've continued to keep plant and soil health the main focus in our farming operation decisions."
