An improved cultivar, based on17 genotypes of S.cpitata and six of S.macrocephala, was developed at the Embrapa Beef Cattle Research Center. Campo Grande, Brazil. The aim was o create durable, race non-spedific resistance to anthracnose controlled by polygenic factors. A mass hybridisation technique was employed to produce a higth degree of genetic diversity and sizeable quantities of seed of hybriderived progenies of Brazilian and Venezuelan genotypes of S.capitata. Outcrossing resulted in a significant improvement in the forage production of progeny of Venezuelan accessions. The multicross was evaluated in multilocational trials, each representing a large tract of country in the Cerradis ecosystem along a north-south transect from lat 6 to 20 S. The genetic shift that accourred in S. capitata was a key element in the formation of the new cultivar. It is a complex mixture of two especies, and a reombination of murch desired forage tratis of Brazilian x Venezuelan genotypes, high forage and seed yields coupled eith anthracnose resistance. The new cultivar with its diverse genetic make up has a wide application in the acid-soil savannas of tropical America. It was released by Embrapa for the Cerrados in 2000. |
