Abstract

Sowing of non-conventional hybrids is a real possibility to increase maize grain yield in areas of medium productive potential from altitudes of 1 200 to 1 700 m of the Guerrero’s mountains and similar regions, where different ecological niches predominate, in which has been difficult to make specific improved material available to farmers. Therefore the INIFAP’s Maize Breeding Program based in Iguala, Guerrero, since 1985 has been working on the use of native populations of subtropical origin per se or in combination with improved maize and experimental lines till the generation of the new ‘HV-240’ varietal hybrid, obtained with native and improved germplasm so that it shows greater adaptation and better plant type than native maize, which is planted in 70% of the area cultivated with maize in the state of Guerrero. The ‘HV-240’ is characterized by a wide adaptation, a biological cycle of 125 days on average, with 64 days to male and female flowering, plant height of 250 to 270 cm, reason why it shows greater resistance to bending, and grain yield from 5 to 6.5 t ha-1.
