The trial of experimental white corn

hybrids from PRM-2001 was evaluated in 14 localities in

Central America during 2001. The objective was to assess

their grain yield and agronomic characteristics of the

experimental hybrids. Twelve triple hybrids and one double

hybrid, bred from simple crosses from CIMMYT and

superior lines from different PRM projects, mainly of hybrids

and stunting , including one reference entry (CML 247 x

CML 254) and on control, were evaluated. A Complete

Randomized Experimental Block design with three

replication was used. The variables registered were: grain

yield, ear rot, male and female flowering, ear covering and

aspect, root and stalk lodging. The results obtained for grain

yield, through the 14 environments, varied between 4.75 to

6.37 t/ha, with a general media of 5.60 t/ha and variation

coefficient of 9.9%. In ear rot, the hybrids showed values of

4.3 and 8.0%, being lower than the controls.
