Abstract
The current study was carried out at CCSHAU College of Agriculture, Bawal, during 2020-21 to study the phenotypic variation and progeny performance in Moringa oleifera. The experiment was conducted after following Complete Randomized Block design (CRD) with three replications. The observations were recorded for phenotypic variation i.e. Plant height (m), diameter at breast height (DBH) (cm), crown spread (m2), length of pod (cm), pod diameter (mm), pod weight (g), number of seeds per pod, 100 Seed weight (g), and other biochemical characters viz., moisture content (%), fat (%), crude protein content (%), crude fibre content (%), ash content (%), total sugar content (g/ 100g) in twenty-four genotypes collected from the states of Haryana and Rajasthan. The progeny performance of these genotypes was assessed in terms of germination percent (%), collar diameter (cm), number of leaves, shoot length (cm), root length (cm), total plant height (cm), Shoot Vigour Index (SVI), Root Vigour Index (RVI), fresh weight of seedlings (g), dry weight of seedlings (g). The genotypic and phenotypic coefficients of variation (GCV and PCV respectively), and heritability were also studied.
Wide range of variability was observed in tree growth, Genotypes collected from Haryana state i.e. G-9 yields maximum plant height whereas G-3 outperformed in diameter at breast height (DBH) and crown spread. For pod parameters, G-11 found to be superior whereas P-15 and P-22 were superior at nursery stage. Similarly higher significant results were observed for moisture content, fat, crude protein, crude fibre, ash content (%), total sugar content (g/ 100g) in genotypes G-21, G-20, G-5, G-22, G-12 and G-11 respectively. Higher genotypic and phenotypic coefficients of variation were discovered for trends in crown spread, diameter at breast height (DBH), and pod weight, number of leaves, Shoot Vigour Index (SVI), shoot length, plant height, ash content and 100 seed weight. Excessive heritability as a percentage of mean was observed for crown spread, 100 seed weight, crude fiber, shoot length, plant height, and diameter at breast height (DBH), number of leaves, fat content, and crude protein.
