摘要：

This work examines the relationship between the osmoregulation capability of various pea cultivars and breeding lines, grown in climatic chambers (subjected to one dehydration cycle), and their yields in the field under drought conditions. The relative water content at an osmotic potential of - 1.5 MPa was used as an indicator of osmoregulation. There was a linear relationship between yield and osmotic adjustment in two years (R = 0.70 and R = 0.92), but not in a rainy year, when drought stress was slight.
