The objective of this work is to assess the participatory five new selected varieties in the three cotton growing region of Benin in order to compare their performance with the commercial variety. The experiment was carried out in three cotton growing regions in farmers’ fields during two years (2011 and 2012). The results indicated that density and cotton seed yield (CSY) were significantly affected by environment (p˂0.000). Significant effect of genotypes was observed with boll average weight (BAW). However, there is no significant difference among genotypes for variables density and CSY (p˃0.05). In addition, the effect of genotypes × environments interaction on density was highly significant (p≤ 0.01). Savalou and Kandi have more favorable conditions for cotton seed yield for all genotypes. The genotypes Djougou 8/5, H-279-1, Kandi ¾ and Okpara 3/5 were adapted to the environments of Kandi and Savalou and were more stable in the production of bolls and cotton seeds yield. Therefore, these genotypes could be used as breeding stock that could be incorporated in crosses with the objectives of improving the previously mentioned traits.
