Table 3 Phenotypic (above diagonal) and genotypic (below diagonal) correlations of 16 agro-morphological traits in 120 amaranth genotypes grown at Hawassa University agricultural research site in 2020 and 2021 cropping seasons.

From: Study on characters associations and path coefficient analysis for quantitative traits of amaranth genotypes from Ethiopia

  1. Axillary inflorescence length (cm) = AIL, leaf yield (t/ha) = LY, grain yield (t/ha) = GY, days to maturation = DM, leaf length (cm) = LL, leaf width (cm) = LW, branch number (number) = BN, leaf number (number). LN, plant height at flowering stage (cm) = PHF, plant height at maturity (cm) = PHM, terminal inflorescence laterals length (cm) = TILL, terminal inflorescence stalk length (cm) = TISL, grain sink filling rate (kg ha−1 day−1) = GSFR. The green and yellow colors indicate the strength of correlation; green is positively correlated; green to light green indicates strong to weak positive correlation; yellow is negatively correlated, and yellow to light yellow indicates strong to weak negative correlation. Below the diagonal is the correlation coefficient; while above the diagonal is the significance level. ns = non- significant (p ≤ 0.05), *significant (p ≤ 0.05),**highly significant (p ≤ 0.05), ***very highly significant (p < 0.0001).
