| Abstract: | According to the basic concept of precision and the methods of analysis of variance (ANOVA), precision of experiment and variety comparison in regional crop trials were studied and developed; expected variety comparison precision (EVCP) and realized variety comparison precision (RVCP) were proposed, and the calculation formulae and application examples of them were presented. The precisions of regional cotton trials in Yellow River Valley and Changjiang River Valley were investigated based on the trials data from 1980 to 1999. |
| Keywords: | Regional trial Precision Variety comparison precision |
