| dc.description.abstract | Leafy Mustard (Brassica juncea var. rugosa) is a popular green vegetable grown in plains and hills of Northern India. It is a rich source of vitamins, minerals and protein. The present investigation carried out with 31 germplasm during November – February 2018 – 2019 at Vegetable Research Center (VRC). Nutraceutical properties of each genotype were determined at G.B.P.U.A & T. Laboratory Pantnagar. The estimation of micronutrient (iron, zinc manganese by atomic absorption spectrophotometer), macronutrient (phosphorus and potassium by spectrophotometer and flame photometer), protein and nitrogen (by Kjeldahl method) were done. Analysis of coefficient of variation showed significant differences among the genotypes for all the traits. The genotype which recorded highest green leaves yield (kg/ha) was PLM-15 (400kg/ha). The phenotype coefficient of variation recorded highest in green leaves yield per plant (g) was PLM-16 (350.00g) and phenotype coefficient of variation recorded highest in green leaves yield (kg/ha) was PLM-15 (400kg/ha). Lowest GCV and PCV value was recorded in days to last leaf harvest. Highest value of heritability was reported for green leaf yield/plot (99.90%). Highest genetic advance was obtained in leaf area (169.99) while highest genetic advance as % of mean was recorded in leaf area (31.37%). All 31 genotypes showed variability in neutraceutical property. Highest protein content (33.38%), nitrogen (5.55%), phosphorus (1400.33 mg/100g), potassium (2770.00 mg/100g), iron (30.56 mg/100g), zinc (5.73 mg/100g) and manganese (4.94 mg/100g) was observed in PLM-16. The 31 genotypes were classified into 6 different clusters based on genetic distance. The analysis showed the highest intra cluster distance in cluster III (451.92) having 5 genotypes and the highest inter cluster distance (20529.11) among cluster V having 1 genotype and cluster VI having one genotype. Thus with these findings, we can state that above genotypes were promising and can be utilized for further improvement programme in leafy mustard. The genotypes which are rich in neutraceutical properties can be used for plant biofortification. | en_US |
