摘要

Hardwickia binata Roxb. is an important multipurpose tree species renowned for its high-quality timber value. The present study aimed to evaluate the morphological and biochemical variation among selected accessions of this species collected from different geographical regions of central India. The result revealed significant variation in both morphology and biochemical traits across populations. Analysis of morphological data revealed that in H. binata, tree height ranged from 8.5 to 27.0 m, clear bole height from 4.0 to 22.0 m, girth at breast height from 38 to 143.0 cm, crown diameter from 2 to 5.0 m, and number of primary branches from 2 to 12. A positive correlation was observed among tree height, clear bole height, and girth at breast height. PCA indicated that tree height contributed the most to the total variation (80.52%). Based on morphological variables, cluster analysis classified accessions into five distinct groups. Genetic estimates indicated substantial variability among genotypes, with a broad range of variation. The PCV was higher than both the GCV and ECV for all traits. The heritability (98.94%) and GA (31.45) recorded maximum in GBH, while the highest GAM (41.23%) was observed in Primary branches. Qualitative biochemical estimation confirmed the presence of various bioactive constituents, except alkaloids. Quantitative biochemical estimation revealed that accessions from the Kanker population exhibited the highest level of TCC (1.240 mg GE/g dry wt), TFC (0.742 mg QE/g dry wt), and TPC (2.870 mg GAE/g dry wt), highlighting their potential for future research and conservation efforts.
