Correlation Analysis of Leafy Mustard (Brassica juncea var. rugosa) Genotypes for Morphological and Neutraceutical Attributes under Tarai Condition of Uttarakhand, India

Abstract

The phenotype coefficient of variation recorded highest in green leaves yield per plant and green leaves yield (kg/ha). Highest value of heritability was reported for green leaf yield/plot (99.90%) followed by green leaf yield/plant (99.07%), leaf area (98.24%) and days to last leaf harvest (73.42%) while lowest value of heritability was observed in no. of leaves/plant at 30 days (47.52%). High heritability in conjunction with high genetic advance was observed for leaf area (169.99). Highest genetic advance as % of mean was recorded in leaf area (31.37%) followed by green leaf yield/plant (26.39%), Leaf width (25.04%) and Green leaf yield/plot (23.73%). The genotypic and phenotypic correlation study revealed that leaf yield per plant was found to be positively and significantly correlated with Leaves per plant at 30 days, Days to last leaf harvest, Phosphorus (mg/100g) and Potassium (mg/100g) while, negative significant association of leaf yield was observed with leaf width (cm) and leaf length with petiole (cm).
