Grain yield and seed size are key breeding objectives for the chickpea breeding program in Morocco. Six winter-type chickpea (Cicer arietinum L.) varieties released between 1992 and 2015, and two candidate lines, were evaluated under different environments in order to study the stubility of grain yield and seed size across locations and to assess the genetic gain.. The varieties and candidates lines were evaluated in field experiments using a randomized complete block design with four replications in 9 different environments. The results showed that in 27 years of breeding, the average value of hundred seed weight improved from 33 to 47 g. Greater genetic progress was made for seed size than for grain yield. Average yearly genetic gains of 1.30 were recorded for seed size. Most varieties had wide adaptation and responded positively to the increase in environmental index. However, differences between varieties in terms of adaptation and stability were observed. A clear increase in seed size, an important market trait for chickpea in Morocco, is observed in the more recent improved genotypes. The improvement in seed size had limited penalty on yield as shown by a joint stable to slightly increasing or decreasing in grain yield thought years of breeding. These results could help draw more attention to the importance of winter-sown chickpea and enhance its adoption in Morocco. The end results could be the enhancement of national food production and security.

谷物产量和种子大小是摩洛哥鹰嘴豆育种计划的关键育种目标。六冬型鹰嘴豆（Cicer arietinum L.）在不同环境下对 1992 年至 2015 年间发布的品种和两个候选品系进行了评估，以研究不同地点的谷物产量和种子大小的稳定性并评估遗传增益。在 9 个不同环境中具有 4 个重复的随机完整区组设计。结果表明，经过27年的育种，百粒重平均值由33g提高到47g。与谷物产量相比，种子大小的遗传进展更大。种子大小的平均年遗传增益为 1.30。大部分品种适应性广，对环境指数的上升反应积极。然而，观察到品种之间在适应性和稳定性方面的差异。种子大小明显增加，在摩洛哥鹰嘴豆的一个重要市场性状，在最近的改良基因型中观察到。种子大小的改善对产量的影响有限，这表现为经过多年的育种后谷物产量的稳定到略微增加或减少。这些结果有助于引起人们对冬播鹰嘴豆重要性的更多关注，并促进其在摩洛哥的采用。最终结果可能是加强国家粮食生产和安全。这些结果有助于引起人们对冬播鹰嘴豆重要性的更多关注，并促进其在摩洛哥的采用。最终结果可能是加强国家粮食生产和安全。这些结果有助于引起人们对冬播鹰嘴豆重要性的更多关注，并促进其在摩洛哥的采用。最终结果可能是加强国家粮食生产和安全。
