Abstract: About ten countries have adopted Bt-cotton since its commercial release in the USA in 1996. This release immediately has led to raise the concern of Monsanto's monopoly and loss of varietal diversity in adopting countries. There are very few studies addressing the actual state of the cotton variety markets in the adopting countries. This article proposes an analysis of these markets in China along what is observed in other countries where Bt-cotton is grown. Monsanto's monopoly in supplying Bt-genes, indeed encountered in all countries except China, must be distinguished from monopoly of Monsanto's varieties. This latter monopoly is not always confirmed, and surely not in China. In this country, very active competition has taken place, with a tendency for breeders to propose varieties integrating both Bt and hybrid F1 traits. Furthermore, competition has become excessive and implies negative effects to producers as well as to breeding and seed distribution companies, hence forcing the Chinese government to engage regulation policy
