Variabilitas Genetik Dan Heritabilitas Karakter Agronomi Beberapa Varietas Kenaf (Hibiscus Cannabinus L.)
ABSTRACT
Kenaf (Hibiscus cannabinus L.) is a potential fiber crop widely utilized in
eco-friendly industries such as textiles, biocomposites, and paper. However, the
development of kenaf in Indonesia remains limited due to the lack of superior
varieties with high fiber productivity. This study aimed to evaluate the genetic
variability, heritability, selection response, and phenotypic correlation of several
agronomic traits among kenaf varieties. The experiment was conducted at the
Experimental Farm of the Faculty of Agriculture, Universitas Riau, from January
to May 2025, using a non-factorial randomized block design with four kenaf
varieties (Karang Ploso 6, Karang Ploso 9, Karang Ploso 14, and Kenafindo 2)
and six replications. Data were analyzed using analysis of variance. The results
showed significant differences among varieties for all agronomic traits. All traits
exhibited narrow genetic variability but most showed high heritability values.
Phenotypic correlations among traits were positive. Plant fresh weight, stem fresh
weight, and stem diameter were identified as potential selection criteria for
improving kenaf fiber yield.
