Behaviour of normal and high quality protein maize varieties for the Gulf of Mexico region.
During Spring .Summer season in 2001 experiments of normal and highquality protein maize were conducted in four locations in theVeracruz State (Cotaxtla, Papantla, Isla and San AndresTuxtla) and Huimanguillo in Tabasco State, to evaluate theiryield and agronomic characteristics and to define theiradaptability under these environments. Thus, the experimentswere stablished under alpha lattice designs 4 x 8 with 32entries and two replications, in plots with two 5 m long rowsand 80 cm between them. The combined analysis for grainyield showed highly significant differences for varieties (V),locations (L) and for the interaction Vx L. Among the bestgenotypes at 0.05 of probability are the normal syntheticvarieties formed with drought tolerant inbred lines, SINT 3SEQ, VS-536 y SINT 9 SEQ and the high quality proteinmaize varieties SINT 1 Q, V-537C, y V-537C Comp. 1. Inreference to the agronomic characteristics, these genotypesregistered good ear and plant aspect and healthiness.Particulary in Cotaxtla, Papantla and San Andres Tuxtla, V-537C Comp 1 (which correspond to the first S1 familiesrecurrent selection cycle of V-537C), registered importantadvantages in yield, ear and plant aspect, lodging, husk coverand ear rot.
