“…Amaranths are traditional leafy vegetables popular in most African countries [1,2]. They are characterized by a high diversity and capacity to adapt to different agro-climatic conditions [3][4][5]. Being C4 type plants like maize and sugarcane, amaranths have a carbon sequestration capacity, which allows them to have a high production of dry matter and protein per unit area [6].…”

The present study was carried out on eighty (80) accessions from Burkina Faso. It has a double objective: to identify the different species of amaranths cultivated and to estimate their agronomic performances. To this end, twenty-four (24) descriptors were used to characterize the collection, according to a Fisher block design with three replications. The survey was conducted at the IDR experimental site in Gampèla. The study revealed a great phenotypic diversity characterized by the existence of qualitative discriminating characters of which the color of the stem and the leaves, the shape and the size of the leaves as well as the color of the inflorescence. These observations allowed us to identify seven morphotypes belonging to three species: Amaranthus cruentus, Amaranthus hypochondriacus and Amaranthus dubius. The analysis of variance showed several discriminating quantitative characters including height, stem diameter, number of branches and number of days to flowering. The green-leaved Amaranthus cruentus species showed the highest yields of leaf biomass (283.57 g) with a long flowering cycle (72.5 days) and a high number of branching (45.6). Oval-leaved accessions with broad, long blades and early flowering were identified belonging to the species Amaranthus dubius. The light green morphotype of Amaranthus hypochondriacus species and accessions of Amaranthus dubius species yielded low foliar biomass.

Grain Amaranths are important nutritional vegetables in the world for their grains and leaves. Twelve grain Amaranth accessions were evaluated for their performances using randomized complete block design with 3 replications in the cropping seasons of 2016 and 2017 to measure variability, Classify the accessions and select outstanding genotypes. Analysis of Variance and accessions performances revealed significant variability among the grain Amaranths. Phenotypic variances were higher in magnitude than genotypic variance for all the traits studied. The high genetic advance was obtained for all the characters except 1000 grain weight (23.61). The genotypic coefficients of variations were lower than the phenotypic coefficient of variations. Heritability ranged from 41.08% for grain yield/plot to 62.18% for plant height at flowering. Grain yield was positive and highly significantly correlated with 1000 grain weight, leaf area but significantly correlated only with leaf length and leaf width. The Principal Component Analysis (PCA) revealed four main components of variations representing 78.06% of the total variability among the 12-grain amaranth accessions. The PCA identified all the 12 traits as strongly correlated with the three principal components. PC1 is well-correlated with plant height at flowering, stem girth, a number of leaves, plant height at maturity, leaf width, leaf length, leaf area and petiole length. The bi-plot analysis classified the accession NG/AA/03/11/010, NGB 01259, and NGB 0127 as having good leaf yield and desired leaf traits, Accession NHGB/09/108, NG/AO/08/04 and NGB 01261 were grouped as better grain yield with good yield attributes, while accession NGB 01234, NHGB 09/09 and NHAC3 are good dual-purpose accessions having good grain and leaf yield.
