摘要
该研究旨在评估从印度不同农业生态区域选取的共 29 个楝树基因型的种子样本,重点关注其形态和生化性状。对所选基因型的楝树种子进行了全面的种子形态评估,包括种子长度(SL)、种子宽度(SW)、100 粒种子重量(SWT)和种仁比(SKR)。此外,还对种子进行了生化分析,以确定其油含量(OC)和氮芥含量(AC)。在 SWT 和 AC 等性状上,观察到了显著的基因型变异,遗传率和遗传进展较高,表明遗传影响很大。相关性和路径系数分析表明,SW 和 AC 对 OC 有正向影响,而 SWT 则有负向直接影响。遗传差异分析将基因型分为五个群组,突出显示了巨大的多样性。这些发现凸显了为育种计划选择楝树优良基因型的潜力,育种计划旨在提高脂肪油和杜鹃素的产量,从而促进可持续农业实践和以楝树为基础的产业。
Assessment of seed and biochemical traits in neem germplasm for sustainable agriculture and industrial applications
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.
