WINNIPEG, Aug. 24 (CNS Canada) – A new study by researchers at the University of Saskatchewan has found that two genetic traits in field peas, longer flowering times and higher pod counts, are also indicators of heat stress tolerance. Rosalind Bueckert, lead researcher, said heat tolerance in peas depends on several traits but higher pod numbers and longer flowering are most important. It marks the first time the location of genes that affect heat stress have been located.

Widespread rain in Minnesota has limited harvest times for many producers as dry edible bean crops advance to setting pods stage or beyond. The crop condition is rated 73 per cent good to excellent in the state.
