Summary

The stabilities of plant height and yield for rice varieties grown in Sri Lanka were calculated by regression analysis. High yields were produced by both stable and unstable varieties in the wet season, but in the dry season high-yielding varieties tended to be of above-average stability. The yield of the newer, shorter varieties exceeded those of older varieties except at low nitrogen levels, and the new varieties were of above-average stability.
