| Abstract: |
| AMMI(Additive Main Effects and Multiplicative Int
eraction Model) was adopted to conduct comprehensive evaluation on the yield of
ten cultivars at seven sites involved in the regional testing of potato in Gansu
Province during 2007—2008. The results indicated that the stability of tested
cultivars was as follows: L0206-6＞L0227-17＞L0227-18＞Tian 2008-8-2＞Fushu 3＞
CK＞34-126＞98-6-2＞35-62＞Longshu 6; the production stability of L0206-6 and 98
-6-2 was higher than others, while that
of Longshu 6 was the lowest; the yield of L0227-17, L0206-6, L0227-18 and Tian 2
008-8-2 was relative high, while that of 98-6-2 was the lowest. The results also
suggested that the discriminative parameter varied among different testing site
s, which could be ranked as: Tianshui＞Huichuan＞Anding＞Jingning＞Linxia＞Qinwa
ngchuan＞Tanchang. Therefore, Tianshui was the site
with a highest discrimination, while Tanchang was the site with a lowest discrim
ination in selecting cultivars. The principle component of AMMI model could expl
ain 93% of total sum of squares of interaction, being more effective in analyzin
g the interaction between gene and environment than the traditional regression m
odel. |
