Abstract

Genetic variability of some morphological traits of 18 amaranth accessions of different species and ecological-geographical belonging were estimated. We studied determinants which characterize the productivity and straight or mediated influence on it (plants height, inflorescence length, mass of seed from one inflorescence, productivity of seed, mass is 1000 seed, length and width of leaf plate, leaf index). The considerable varying of the most characteristics was established. Correlations between them were shown. Close connection between length and width of leaf plate, middle degree of positive dependence between leaf length and leaf index, between inflorescence length, mass of seed from a 1 inflorescence and with 1 m2, between mass of seed from a 1 inflorescence, mass 1000 seed and mass of seed with 1 m2. For other combinations of traits insignificant correlations is marked.
