The paper presents the results of research made in 2007 year at the Biobasis within USAMV-Bucharest Campus regarding morphological and biological characteristics, chemical composition and yield quality of Amaranthus hypochodriacus species. It worked with 5 different cultivars, coming from the world collection: Manna de Montana, Rio san Lorentzo, Nepal, Guarijio and New-Mexico. The duration of the vegetation period was of 130-147 days, the late cultivar was Manna de Montana, with a vegetation period of 147 days, and most early proved to the Rio San Lorentzo cultivar with 135 days of vegetation. The height of Amaranthus hypochodriacus plants varied between 132.8 cm for New-Mexico cultivar and 75.3 cm for Nepal cultivar. The productivity of Amaranthus hypochondriacus cultivars was illustrated by grains yields of 11.1-25.3 q/ha, data which mirror an important adjustment capacity to the cropping condition in the area and resistance to drought and high temperatures. The chemical composition of grains was following: 16.95% proteins; 62.02% starch; 5.56% lipids; 4.68%  fibres and 3.67% ash.
