The classification of faba beans into winter and spring forms is determined by their genetically inherent cold hardiness and response to temperature regimes. Winter varieties are adapted for overwintering, whereas spring forms are intended for spring sowing and lack sufficient frost resistance.

The primary difference between faba bean forms lies in their ability to withstand low temperatures. Winter forms possess specific cold-adaptation genes, allowing them to develop in temperate climate conditions. Spring forms, which predominate in most regions, are intended for spring planting and are not adapted to winter frosts.
Winter forms are attractive due to their potential for higher yields resulting from an earlier start to the growing season and the utilization of spring moisture. However, their cultivation is restricted to specific agro-climatic zones where there is no risk of winterkill, as the differences between the forms are strictly anchored by genetic loci that determine frost resistance and the schedule for accumulating growing degree-days.
