2002年旱季，在塞内加尔河谷（SRV） 3个农业生态区（三角洲、居耶尔湖区（GLZ）和中谷区（MVZ）对Fleur 11、55-437、73-33、78-936、GC8-35和h<s:1> tive de Sefa） 6个花生品种进行了产量性能和稳定性评价。三角洲、MVZ和GLZ的产量环境指数分别为3.7、2.5和1.7 t ha-1。GC8-35在三角洲和MVZ分别表现出4.5和3.9 t ha-1的良好响应。该品种对不利环境非常敏感，在GLZ产量下降至1.62 t hm -1，回归系数为1.4190(>1)，截留系数为负。GC8-35品种的平均平均最高，为3.3 t hm -1，显示出超常的生产潜力开发能力，Delta和MVZ的偏差分别为+21.6和+56%。该品种（GC8-35）对有利环境具有特殊的适应性。花11号在Delta和MVZ分别表现出4.2和2.6 t ha-1的优良性能。它具有利用有利环境的非凡能力。GLZ、MVZ和Delta区的偏差分别为+ 23.5%、+ 4%和+13.5%。回归系数非常接近于单位，证实了小花11号具有良好的可塑性（适应能力广）。在三角洲和MVZ地区，适居玉米的产量分别为3.6 t ha-1和2.0 t ha-1，而在不利地区，适居玉米的产量为2.4 t ha-1。该品种较弱地利用了有利环境，MVZ和DELTA区的偏差分别为- 20%和- 2.7%。它表现出对不利环境的特殊适应。品种78-936在三角洲和MVZ的产量也适中，分别为3.4和2.9 t ha-1，但对不利环境的敏感性特别高，产量降至0.4 t ha-1。该品种在所有位点均呈现负偏差。品种55-437在三角洲和MVZ的产量超过3 t ha-1，而73-33仅在三角洲达到3 t ha-1。三角洲和MVZ的偏差为负或为零，这些品种对不利环境的特异性适应较弱，偏差为+ 5.8%
Six groundnut varieties (Fleur 11, 55-437, 73-33, 78-936, GC8-35 and Hâtive de Sefa) were tested in three agroecological zones of Senegal River Valley (SRV) (Delta, Guiers Lake zone (GLZ) and Middle Valley zone (MVZ)) during the dry season 2002 to evaluate their yield performance and stability. The yield environmental index was 3.7, 2.5 and 1.7 t ha-1 in Delta, MVZ and GLZ, respectively. GC8-35 showed good response with 4.5 and 3.9 t ha-1 in the Delta and MVZ, respectively. The variety was very sensitive to unfavourable environment with yield decreasing to 1.62 t ha-1 in GLZ, as indicated by the coefficient of regression of 1.4190 (>1) and the negative constant of interception. With the highest general average of 3.3 t ha-1, GC8-35 variety showed exceptional capacities to exploit their production potential, as shown by the deviation of +21.6 and +56% in Delta and MVZ, respectively. This variety (GC8-35) had a specific adaptation to favourable environments. Fleur 11 showed a good performance with 4.2 and 2.6 t ha-1 in Delta and MVZ, respectively. It had exceptional capacities to exploit the favourable environments. It showed a deviation of +23.5, +4 and +13.5% in GLZ, MVZ and Delta zones, respectively. These results reinforced by the coefficient of regression very close to unit confirm the good plasticity of Fleur 11 (broad adaptation capacity). Hâtive de Sefa gave moderate yield of 3.6 and 2.0 t ha-1 in the Delta and MVZ, respectively, with however the best response in unfavourable zone (2.4 t ha-1). This variety, weakly exploited favourable environments with deviations of -20 and -2.7 % in MVZ and DELTA zones, respectively. It showed specific adaptation to unfavourable environments. The variety 78-936 gave also moderate yield of 3.4 and 2.9 t ha-1 in the Delta and MVZ, respectively, with however a particularly high sensitivity to unfavourable environment, its yield decreasing to 0.4 t ha-1. This variety showed negative deviation in all sites. The variety 55-437 yielded more than 3 t ha-1 in the Delta and MVZ, whereas 73-33 reached 3 t ha-1 only in the Delta. With a negative or zero deviation in the Delta and MVZ, these varieties showed a weak specific adaptation to unfavourable environments, in which they achieved +5.8 % deviation
