| Abstract: |
| The aim of this study is to use AMMI model to analyze yield and agronomic traits, including plant height, tuber quantity per plant, stem quantity per plant, mature days, and tuber fresh weight per plant, in 2010-2011 potato regional test results in Guizhou province. The study results showed that the interact prineiple component of AMMI model is capable of explaining 90.64%,90%,86%,82%,81% of total sum of squares of yield, tuber quantity per plant, stem quantity per plant, mature days, tuber fresh weight per plant, respectively. The species stability, adaptability and high yield ability of three varieties, W04-36, 0402-2 and Mila, were better than rest species among the eleven of species tested in Guizhou potato regional test. W04-36 can be promoted and planted in large areas.Yield ability of
Heimeiren was the worst among all the tested varieties. Among the five test sites, Divalues of Bijie and Anshun were larger than others. Both sites have a high diseriminability for variety. Liupanshui has the lowest discriminability for vari-ety; therefore it is suitable for planting many different species. |
