| 摘 要： | 本文利用Ｅｂｅｒｈａｒｔ和Ｒｕｓｓｅｌｌ（１９６６）提出的方法，评价了１９９０年参加国家级东北片第四轮马铃薯品种区域试验中晚熟组６个点的３个品系，克８６３，春薯８４—８和呼单８１—２１３，以及对照品种克新２号的产量稳定性．克８６３和春薯８４－８的块茎产量显著高于对照品种克新２号，而呼单８１－２１３的产量和对照差异不显著．４个品种（系）的ｂｉ和１差异不显著，表现出显著差异，克８６３和克新２号的Ｓ和０差异显著，而春薯８４－８和呼单８１－２１３的Ｓ和０差异不显著．产量最高者克８６３产量不稳定，春薯８４－８表现出平均稳定性。

| Abstract: | Stability analysis was carried out for tuber yield of three cloncs, Ke863, Chunshu 84-8and Hudan 81-213 and one control cv. Kexin 2 which had been tested in the Fourth NationalPotato Regional Trial in Northeastern Part of China in 1990, using the method proposed byEbcrhart and Rustrcll (1966). The tuber yicjds of Ke 863 and Chunshu 84-8 were significantlyhigher than the control cv. Kexin2, whereas the yield of Hudan 81-213 was not differentaignificantly from the control. The values of biwas not different significantly from unity forthe fpur cultivar (cloncs) tested while S shown difference in magnitude. The S of Ke 863and Kexin 2 was different statistically from zero but Chunshu 84-8 and Hudan 81-213 wasnot. The highest yielder Ke 863 was unstable while the second higheast Chunshu 84-8 shownaverage stability. |
