Considering the increasing demand, reducing dependance on wild/ semi-wild population and promotion of cultivation is the need of the hour. Seedling progenies are known to have considerable variability of commercial significance. To identify the superior germplasm with desirable traits, systematic efforts are required. Though such screening from natural population could help in identifying superior genotypes, the data on various yield related traits could be misleading due to differences in the growing conditions of the natural stands. In the present study, the conserved germplasm was evaluated to understand the variations for leaf, fruit and seed morphological parameters apart from their harvesting patterns, yield traits, drying recovery etc. Results revealed that collections showed significant variations for these parameters and unique types viz.

Experiments were carried out using 20 accessions of <i>L. sativus</i> and three accessions of <i>L. cicera</i>. Anther dehiscence and stigma receptivity were determined through microscopic observation and hydrogen peroxide test, respectively. Pollen viability was assessed through in vitro pollen germination and fluorescein diacetate (FDA) test. Flowers were found to be bisexual and protogynous, with self-pollination favored by the cleistogamous nature of flowers. Five flower-development and three pod-development stages were classified in both species. The timing of all stages differed significantly among the accessions studied. Stigma receptivity was observed to occur 2–4 days before anther dehiscence and persisted until flower wilting.

Its homeland harbors a wide spectrum of genetic diversity, relevant to various desirable horticultural traits. Assessing genetic variability for varietal enhancement necessitates a comprehensive capture of both quantifiable and non-quantifiable morphological characteristics. In this study, 49 accessions were meticulously evaluated and characterized for 38 diverse qualitative and quantitative morphological traits. Commercial <i>Aonla</i> cultivars, primarily selected, typically exhibit a semi-spreading or spreading nature. The <i>Aonla</i> germplasm showcases notable discrepancies in morphological traits, spanning growth, flower, bark, and fruit characteristics, reflecting the diversity across its tree. Fruit aspect ratio, defining the relationship between diameter and length, serves as a crucial identifying feature. Variations in total soluble solids, ascorbic acids, pulp: stone ratio, pulp content, fruit dimensions, weight, circumference, and yield per plant were observed across genotypes and varied from 7.5–12.1°brix, 340.72–550.38 mg/100 g, 13.25–19.71, 13.50–42.35 g, 1.79–4.17 cm, 2.28–4.27 cm, 15.97–45.19 g, 7.04–13.44 cm, and 45.70–105.14 kg/tree, respectively.

Path coefficient analysis identified traits with direct and indirect effects on yield per plant, while principal component analysis offered a comprehensive overview of variability among genotypes. Cluster analysis categorized genotypes into distinct groups, revealing valuable traits for achieving high fruit yield.

To gain insight into the repetitive DNA fractions in kenaf, the organization of 5S and 35S rRNA genes, as well as telomeric signal patterns were studied by a molecular cytogenetic approach. Using multi-color fluorescent in situ hybridization, distinct rDNA loci and <i>Arabidopsis</i>-like telomere signal patterns were revealed. The 5S rRNA genes were conserved in kenaf and localized in interstitial regions of two chromosomes across all accessions. The 35S rRNA genes were variable across the kenaf accessions and localized at sub-terminal ends and rarely interstitially in eight or six chromosome arms.

Flowers were collected at anthesis; the morphology of calyxes, corolla and pollen grains was characterized; DNA barcoding analyses were performed. All taxa were identified only as <i>O. basilicum</i> by molecular analyses, but two haplotypes were distinguishable. All taxa were identifiable due to the presence/absence of specific glandular trichomes, and by pollen size and number of colpi. ‘Cinnamon’ and <i>O.</i> × <i>africanum</i> showed more morphological affinities to each other, but histochemical analyses suggested the separation of the three taxa. Pollen grains from ‘Cinnamon’ had the smallest diameter in polar view and were hexacolpate, while ‘Blue Spice’ pollen showed the highest diameter with grains being hexacolpate/octacolpate, similarly to <i>O.</i> × <i>africanum</i>.
