During 1990, a maize quality breeding programme was initiated at the Instituro Fitotecnico de Santa Catalina aimed at obtaining high quality protein, waxy and double recessive hybrids capable of bein used for human and animal nutrition, as well as new staples for several industries. Amongst other traits, evolutive cycle length was measured in the foundational materials, backcrosses, inbreds and different types of hybrids derived from them, through Heat Unit Requirements (HUR) and nunmber of days to mid silking (R1 stage according to Hanway scale). In general terms, selection by precocity associated to quality breeding was successful, and unpublished data from a single hybrid field trail evaluated in Llavallol during the growing season 2002/3 showed that the evolutive cycle length of these was dominated by the most precocious parent of the cross.
