Abstract

During Spring .

Summer season in 2001 experiments of normal and high

quality protein maize were conducted in four locations in the

Veracruz State (Cotaxtla, Papantla, Isla and San Andres

Tuxtla) and Huimanguillo in Tabasco State, to evaluate their

yield and agronomic characteristics and to define their

adaptability under these environments. Thus, the experiments

were stablished under alpha lattice designs 4 x 8 with 32

entries and two replications, in plots with two 5 m long rows

and 80 cm between them. The combined analysis for grain

yield showed highly significant differences for varieties (V),

locations (L) and for the interaction Vx L. Among the best

genotypes at 0.05 of probability are the normal synthetic

varieties formed with drought tolerant inbred lines, SINT 3

SEQ, VS-536 y SINT 9 SEQ and the high quality protein

maize varieties SINT 1 Q, V-537C, y V-537C Comp. 1. In

reference to the agronomic characteristics, these genotypes

registered 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 families

recurrent selection cycle of V-537C), registered important

advantages in yield, ear and plant aspect, lodging, husk cover

and ear rot.
