Cold tolerance of pea

Pisum sativum L.

The cold tolerance of peas determines the feasibility of early sowing and the resistance of seedlings to spring frosts, with a biological minimum for seed germination of 1–2 °C.

In the reference 11 varieties crop Pea, where this is mentioned in the description.

For field peas, cold tolerance is a key adaptive trait that allows for early sowing dates to effectively utilize spring moisture reserves. The biological minimum for the onset of seed germination for this crop is 1–2 °C.

Highly cold-tolerant forms are capable of withstanding frosts down to -6…-8 °C at the seedling stage. However, during the fruiting period, the crop's sensitivity increases, and the critical temperature threshold for frost damage to pods is considered to be the range of -2…-3 °C.

In modern breeding, cold tolerance is assessed primarily through field observations of seedling survival and by comparing new lines with regional standards. For regions with high-risk farming, this trait is a determining factor in selecting varieties capable of withstanding sharp spring temperature fluctuations.
