The field experiment was conducted to study the “Genetic Variability and Correlation Analysis for yieldrelated traitsin Amaranthus (Amaranthus spp.)” was conducted at the Department of Horticulture, College of Agriculture, Indore (M.P.) during Rabi 2024-25. Eleven genotypes of Amaranthus were evaluated in a Randomized Block Design with three replications to assess genetic variability for yield and related traits. full-size variations have been located amongst genotypes for all characters, indicating huge genetic variability. Correlation coefficients had been estimated among yield and its factor tendencies at phenotypic and genotypic degrees to understand the inter-relationship among the characters. It presents records approximately the character, volume and direction of selection strain to be implemented for realistic attention. excessive heritability coupled with slight genetic advance was recorded for developments which include plant peak, stem diameter, and wide variety of branches according to plant, suggesting additive gene movement. vast and advantageous correlation changed into observed for leaf yield per hectare (quintal) with seed yield in keeping with hectare (q), seed yield in keeping with plant, harvesting index, leaf region, sparkling weight of leaf, leaf width at harvest, no of inflorescence per plant at harvest, no of leaves according to plant at harvest. On the basis of mean performance of the genotypes, large range was observed for most of the traits under study. It was observed that leaf yield per hectare (quintal) varied from 45.92 qt/ha (AMARANTHUS VIRIDIS) to 127.34 qt. (INDORE-AMA 17-18-133) with mean of 75.03 qt. seed yield per hectare (quintal) varied from 1.26 qt (AMARANTHUS VIRIDIS) to 3.84 qt (INDORE-AMA 17-18-104) with mean of 2.7 qt. Significant positivecorrelation found with leaf yield per plant (g) (1.000) followed by fresh weight of leaf (g) (0.953), leaf area (cm2) (0.811), harvest index (%) (0.751), seed yield per plant (g) (0.670), seed yield per ha (q) (0.659), number of leaves per plant (0.637), number of inflorescences per plant (0.617) andleaf width (cm) (0.368).
