Abstract
利用直線迴歸分析法來解釋植物穩定性的問題，是本省目前最常用而有效的方法。本文以個人電腦之SAS軟體中最基本的STAT功能系統，編寫出一個穩定性迴歸分析程式，並以一數例說明其進行分析的流程及結果，以幫助農業研究工作者進行區域試驗資料之穩定性迴歸分析。程式之輸出結果內容包含有綜合變方分析、各品系在不同環境下之產量平均值、環境指標估值、迴歸分析之統計值摘要表、穩定性係數對品系平均產量之圖示結果。Linear regression method is widely used to investigate the plant stability in Taiwan. A program written in SAS/STAT software is to presented for regressinon analysis of stability. This program runs on personal computers. The procedure is also illustrated through an example. It is useful to agricultural researchers who are analyzing the varietal performance in regional trials by regression approach. Output contains combined analysis of variance, mean yield of each variety under different environments, environmental index, summary statistics of regression analysis, plotting of stability index to varietal mean.
