Farmers across the world produce between 10 and 13 million tons of field pea every year.  That makes it a top legume crop, just behind dry beans and chickpeas.

But as the global climate changes and temperatures continue to rise, heat stress is becoming a major limiting factor for pea cultivation.

A new study indicates that pea plants with some specific traits -- such as longer flowering time and higher pod numbers -- may be more resistant to heat stress.

The researchers also gained new insights into the genetics of heat tolerance in pea.
