High-resolution genetic map construction and QTL analysis of important fiber traits in kenaf using RAD-seq

Kenaf fiber extracted from kenaf stem bast is an important natural fiber. The genetic basis of yield and quality poorly understood. In the present study, Fiber phenotypic data showed continuous positive distribution or positively skewed distribution. traits its related including plant height, fresh weight, dry weight a correlation. However, there was negative correlation between count. results that agronomic are quantitative controlled by multiple genes. Quantitative trait locus (QTL) mapping useful method for revealing mechanism complex identifying new genomic information to accelerate crop improvement. this total 1,997 polymorphic SNP markers were successfully mapped onto 18 different linkage groups. Meanwhile six QTLs identified based on map using QTL (MQM) method, which assigned three groups, LG16, LG8, LG3. QTL-Plant hight, QTL-Fresh QTL-Dry QTL-fiber yield, while strength count quality. This first study kind quality, will facilitate further understanding molecular these traits. limitations regarding utilization because several large gaps remain in some Therefore, additional need be developed narrow regions.
