It is the objective of this study is to determine the best combinations of some of the important factors contributing to differential killings of barley varieties when given cold treatment at the sprouting stage. Intended sources of variation in this study are varieties, seed size, hardening period durations, freezing period durations, and their possible interactions.

Most varieties had a freezing test response that pretty well reflected their field performance. In Experiment II, all varieties ranked within three places of their rank in field tests. In Experiment I, also, the results agreed with field tests but the overall survival was high, making differentiation of varieties of similar hardiness difficult.
