Stability of inbred lines over a range of environments is variable. The objective of this research was to evaluate field response of inbred lines grown under line source irrigation as a predictor of yield stability of inbred lines over environments. Stability regression analyses were computed on yield data of five widely used inbred lines from a single line source experiment and from an interregional study grown at seven locations. Stability response slopes of inbred line performance under a line source irrigation system and in interregional testing were in perfect agreement when compared by rank order correlation. Line source irrigation experiments could serve as a time and moneysaving alternative to testing at numerous locations in a program of selecting for inbred line performance stability.
