“…Early-maturing groups mature in 70–80 d after sowing, which enables seed harvests, but at the cost of lower biomass. Late-maturing groups grow vegetatively for 130–140 d and yield significantly higher biomass, but late maturation reduces seed quality [ 14 , 15 ]. Therefore, a breeding goal in new Korean kenaf cultivars is to increase both biomass and seed yields per unit area [ 35 , 36 ].…”

“…The population used in the analysis had three stem colors: green, dark purple, and brown, with stem colors other than green having a slightly lower biomass content. Although the non-green stem color was associated with lower biomass, such lines are valuable as breeding material because they produce functional substances such as anthocyanins [ 14 ]. In general, plant pigments are functional substances with various activities, such as antioxidant, antidiabetic, and anti-inflammatory compounds.…”

“…Since the frequency of natural mutations is quite low, it is difficult to discover useful genetic variations in a short period of time. Therefore, generating genetic variations by treating crops with physical or chemical mutagens has been used successfully in mutation breeding [ 14 , 15 ]. Among physical mutagens, gamma rays have been used to induce mutations in various crops, such as rice, soybean, and kenaf, and to breed new cultivars [ 10 , 14 , 16 ].…”

“…Our research group has also developed novel kenaf cultivars via gamma irradiation on seeds of the introduced cultivars and registered them in the Korea Seed and Variety Service. In our previous work, we explored the potential of a novel flower or stem color mutation cultivar, ‘Jeokbong’ and ‘Bora’, as a functional food [ 14 ].…”

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.

Mutation induction and detection of desired mutants represents an accelerated means of reaching the desired superior Variety. In this work seeds of Kenaf varieties NG, HIB18, HIB24 and HIB42 collected from National Centre for Genetic Resources and Biotechnology (NAGRAB) Ibadan, Nigeria were subjected to mutagenesis using sodium azide at concentrations of 0.2%, 0.4%, and 0.6%. These treated seeds were planted in polythene bags in row of Four by Four columns in a completely Randomized Design (CRD) with three replications of each treatments. Data on germination percentage, plant height (cm), leaf number, fresh weight and dry weight were taken. Germination was found to be significantly higher in the control and decreased gradually with increasing mutagen concentration for all the four varieties. Among the treatments, NG at 0.6% SA showed better germination compared to other varieties of the same concentration. This indicated differential intervarietal response to the same dose of sodium azide under the same environmental condition. Analyses of data showed significant differences in all the varieties of Hibiscus cannabinus L. treated with sodium azide compared to control. Results indicate sodium azide improved yield performance of Kenaf. Also, negative effect of sodium azide was observed in plants height in variety NG. These finding suggests that plants Varieties would respond differently to mutagenic treatments of specific dosage or concentration. Since 0.6%SA appears to have negative effects on germination and seedling performance of the Varieties planted it is advisable to use lower concentration of sodium azide.

The kenaf plant is used widely as food and in traditional folk medicine. This study evaluated the morphological characteristics, functional compounds, and genetic diversity of 32 kenaf cultivars from a worldwide collection. We found significant differences in the functional compounds of leaves from all cultivars, including differences in levels of chlorogenic acid isomer (CAI), chlorogenic acid (CA), kaempferol glucosyl rhamnoside isomer (KGRI), kaempferol rhamnosyl xyloside (KRX), kaemperitrin (KAPT) and total phenols (TPC). The highest TPC, KAPT, CA, and KRX contents were observed in the C22 cultivars. A significant correlation was observed between flowering time and DM yield, seed yield, and four phenolic compounds (KGRI, KRX, CAI, and TPC) (P < 0.01). To assess genetic diversity, we used 80 simple sequence repeats (SSR) primer sets and identified 225 polymorphic loci in the kenaf cultivars. The polymorphism information content and genetic diversity values ranged from 0.11 to 0.79 and 12 to 0.83, with average values of 0.39 and 0.43, respectively. The cluster analysis of the SSR markers showed that the kenaf genotypes could be clearly divided into three clusters based on flowering time. Correlations analysis was conducted for the 80 SSR markers; morphological, chemical and growth traits were found for 15 marker traits (corolla, vein, petal, leaf, stem color, leaf shape, and KGRI content) with significant marker-trait correlations. These results could be used for the selection of kenaf cultivars with improved yield and functional compounds. (Jin et al. 2013;Ryu et al. 2017a).The most common phenolic compounds in kenaf are the kaempferol glycoside, caffeic acid, myricetin glycoside, and p-hydroxybenzoic acid (Ryu et al. 2017a). In ayurvedic medicine, the kenaf are used for bilious, blood, diabetes, biliousness, coughs and throat disorders (Alexopoulou et al. 2013;Ryu et al. 2017a This is an Open-Access article distributed under the terms of the Creative Commons Attribution Non-Commercial License (http://creativecommons.org/licenses/by-nc/4.0) which permits unrestricted non-commercial use, distribution, and reproduction in any medium, provided the original work is properly cited.
