Abstract Development of new sugarcane varieties allows to increase sucrose production and faces challenges as new pests and diseases, and soil fertility losses. The objective of this study was to contribute to expand molecular tools in selecting useful progenitors for hybridization programs. With this purpose, 14 RAPDs primers were pre-screened, and four of them which produced clearly resolved, reproducible and polymorphic fragment patterns were selected for genetic analysis of 22 sugarcane variety hybrids. These were used in the Estación de Hibridación at Tapachula, Chiapas, as progenitors in genetic improvement programs. Genetic distance analysis showed three main clusters. The first cluster contained… More >
