“…Breeding methods mainly used in kenaf include introduction breeding, exploiting natural variation, hybridizations, and mutation breeding. Recently, cultivars with new characteristics have become required because of changes in various cultivation environments and industrial demands [ 5 , 11 ]. Therefore, remote crossing and modular and mutation breeding are gradually being more widely used.…”

“…However, the identification of genetic information and relationships using NGS technologies has been limited in kenaf. It is necessary to better understand the genetic basis of important traits in kenaf to improve production and to lay the foundation for molecular breeding efforts [ 11 , 12 , 13 ]. Our current study was the first to attempt GBS analysis targeting kenaf genetic resources and breeding lines for various agronomic traits and/or useful traits for the pharmaceutical industry.…”

“…Novel kenaf cultivars generated by radiation mutagenesis and showing improved seed and biomass yield characteristics have been developed using radiation breeding techniques. The cultivars of Hibiscus species have been generated via hybridization, but the floriculture and/or pharmaceutical industry relies on a limited number of mutated traits established based on specific flower quality parameters and consumer palatability [ 11 , 12 , 13 ].…”

Kenaf (Hibiscus cannabinus L.), in the Malvaceae family, is an important crop for not only fiber production, but also various other industrial materials. We performed phylogenetic analysis and a genome-wide association study (GWAS) of seven agronomic traits: days to flowering, plant height, fresh weight, dry weight, flower color, stem color, and leaf shape, using 96 kenaf genotypes, including gamma-irradiation-derived mutant lines. Genotypes were determined by genotyping-by-sequencing (GBS) and a total of 49,241 single-nucleotide polymorphisms (SNPs) were used in the analysis. Days to flowering, plant height, fresh weight, and dry weight were positively correlated with each other, and stem color was also correlated with fresh weight and dry weight. The phylogenetic analysis divided the 96 lines into nine related groups within two independent groups, and the GWAS analysis detected a total of 49 SNPs for days to flowering, plant height, fresh weight, dry weight, flower color, stem color, and leaf shape with −log10(P) ≥ 4, of which 22 were located in genic regions. The detected SNPs were located in genes with homology ranging from 45% to 96% to plants of the Malvaceae and Betulaceae, and these genes were found to be involved in plant growth and development via various pathways. Our identification of SNP markers related to agronomic traits is expected to help improve the quality of selective breeding programs for kenaf.

Kenaf whole stems were obtained from kenaf plantation located in Chendor, Cherating, Pahang. The stems were cut into small particles with sizes ranging between 0.5 mm to 2.0 mm. Kenaf particles were treated using 2 % NaOH solution. Phenol formaldehyde (PF) adhesive was used to bind the kenaf particles together with resin contents of 8 and 10 %. The objectives of this study were to evaluate the effect of resin content on mechanical and physical properties of treated kenaf particleboard. The boards were cut and tested according to the Malaysian Standard (MS1787:2004) for furniture grade particleboards for use in humid condition. Results showed that the values of modulus of rupture, modulus of elasticity and internal bonding strength increased with an increase in resin content, while thickness swelling and water absorption increased with a decrease in resin content. Kenaf board treated with sodium hydroxide gave the highest value of bending strength and internal bonding strength compared to untreated particleboard which acted as a control board. Although all boards did not achieve the minimum standard values requirement according to the Malaysian standard, kenaf has been proven to have a great potential as raw materials in the particleboard industry. Further studies are needed to improve its properties particularly for exterior applications.
