Abstract
The research was aimed to evaluate seed samples of altogether 29 neem genotypes selected from various agro-ecological regions across India, focusing on their morphological and biochemical traits. Neem seeds of the selected genotypes underwent a comprehensive seed morphological evaluation encompassing seed length (SL), seed width (SW), 100-seed weight (SWT), and seed-kernel ratio (SKR). Furthermore, seeds were subjected to biochemical analyses to determine their oil content (OC) and azadirachtin content (AC). Significant genotypic variations were observed, with high heritability and genetic advance for traits like SWT and AC, signifying a strong genetic influence. Correlation and path coefficient analyses indicated that SW and AC positively influenced OC, while SWT showed a negative direct effect. Genetic divergence analysis categorized the genotypes into five clusters, highlighting substantial diversity. These findings accentuate the potential for selecting superior neem genotypes for breeding programs intended at enhancing fatty oil and azadirachtin production thereby contributing to sustainable agricultural practices and neem-based industries.
期刊介绍:
Industrial Crops and Products is an International Journal publishing academic and industrial research on industrial (defined as non-food/non-feed) crops and products. Papers concern both crop-oriented and bio-based materials from crops-oriented research, and should be of interest to an international audience, hypothesis driven, and where comparisons are made statistics performed.
