Abstract
Superiority of the carrot hybrids by comparison with the varieties is revealed by the uniformity and quality of the roots, their productive potential as well a high rate of biochemical compounds accumulation (Sycheva, 1986; Barbara Michalik end al., 1988 Gauchene,1989). During the 2004-2006 period, 10 F1 carrot hybrid combinations were studied in order to establish of the intensity of behaviour of heterosis phenomenon (e.g. suppositional one, real one and competitive one) in some biochemical traits (total carotenes content and soluble dry matter) in order to identify the most valuable perspective hybrids. So, it was performed by comparison of the hybrid value with the average of parental lines and with the best parent as well as with the best grown variety Nantes for each heterosis type, namely suppositional one (Hi), real one (Hr), and competitive one (Hc) which were computed in per cent (%).
