ABSTRACT = {Five genotypes of amaranth were evaluated: four of <i>Amaranthus hypochondriacus</i> L. (collect 153-5-3, 653, 655 and Criollo Tlaxcala) and one of <i>A. cruentus</i> L. genotype 33. Studies were conducted in the cycle of spring-summer (PV) 2000 in Marín, N. L., and PV 2001 and PV 2002 in El Valle del Guadiana, Dgo. A completely randomized design with two repetitions was used, with factorial arrangement using split-plots, divided in space and time. The study population densities (DP) were 125000; 62500; 41666; 32500 and 18666 plants/ha. They analyzed (1) the stability of the genotypes exposed to different environments following Eberhart & Russell (1966), and (2) the grouping of the materials by their yield of grain (RG) and dry forage (FS) by the method of Francis & Kannenberg (1978). Study of interaction G x A indicated that the evaluated materials tended to behave differently in the various localities and evaluated population densities. For RG, genotypes 153-5-3 and 653 were superior to the rest of the genotypes with 30.5 and 29.3 g/plant to a DP of 18666 plants/ha. In yield of FS, genotypes <i>A. cruentus</i> 33 and 153-5-3 were superior to the other genotypes with 150 and 98 g/plant, respectively, to a DP of 18666 plants/ha at the two study sites.},
