A NEW NOBILISATION SYSTEM IN SUGAR CANE (SACCHARUM SPP.)

A NEW nobilisation system (NSN) in sugarcane (Saccharum spp.) is presented to compare with the traditional style of nobilisation (TSN). A group of parents with 2n+n chromosomes has been used to transmit this character to their progenies. The system has increased the chromosome numbers in some parents of our breeding program. We suggest a new nobilisation system in combination with the traditional one in order to increase the genetic base of sugarcane cultivars in any breeding program.
