520			_aTo develop a genetic basis for an in situ maize improvement program, a project was started to select families of half-sibs among landrace varieties in the Puebla valley. In 1992, 136 maize varieties were evaluated; outstanding ones were selected within three early maturity classes. From these outstanding collections, families of half-sibs were derived and evaluated in 1993 at six locations in the Puebla valley. In specific environments, some families equalled or even surpassed the yield of the best check in each earliness class. We concluded that there is high yield potential and great genetic diversity in maize varieties of the Puebla valley which can be used, if improvement is targeted to the conditions where each genotype can express its maximum potential.
