Abstract: Analysis results showed that stability parameter and the high-stable yield coefficient (SPHSYC) is easier but rougher, while coordinate analysis of regression coefficient (CARC) is more accurate and detailed. It is suggested to use SPHSYC for a coarse analysis of regional trial result and to use CARC for a detailed one . Accuracy of a few stability parameters for varieties was also compared and analyzed, which showed that the difference of regression coefficient of the varieties accurately displayed the difference of their stableness.
