Although the total area and production of brown-kernel rice were much lower than those of the white-kernel, the brown-kernel rice was an importance rice line to develop. The study accomplished to test the brown-kernel rice hybrids to their white-kernel parental lines. Three F₃ hybrid lines H₁, H₂, and H₃ were tested versus their consecutive female-parental lines FP₁, FP₂, and FP₃. The parental lines were inbred lines having brown kernels. The hybrids were developed by crossing the female-parental lines having brown-kernels with a male-parental line having white-kernel. Boron was applied at 20 ppm versus 0 ppm to find out whether boron improved the over-all plant performances. The study was done in February – May 2019 at the Lampung State Polytechnics Research Field in South Lampung District using Randomized Complete Block Design with three replications. The result indicated the presence of heterosis that the hybrid lines produced higher than their parental lines and boron improved the vegetative and yield variables. Genetic variability and broad-sense heritability existed in all variables but only the plant height was an unbiased estimate. The other variables were biased by hybrid x boron interaction.&nbsp;&nbsp;</p> <p><strong>Keywords:</strong> boron, broad-sense heritability, heterosis, genetic variability, rice breeding.</p> Saiful Hikam Copyright (c) 2023 Journal of Tropical Upland Resources (J.

Mangrove forests have been utilized by humankind for so long.</em> <em>So far, the use of mangrove areas has been more ecological and tourism-oriented. However, the use of mangrove plants, for example fruit and leaves, to be processed into products has not been widely explored for industry. Processing products using biotechnology principles such as functional food, body care, and natural dyes (batik) can be an alternative in the utilization and industrialization of mangroves to increase the income or standard living of people living around the mangrove ecosystem. This article reviews the current conditions regarding the use of mangrove plants in Indonesia and their potential for the industrialization of products made from mangrove plants.</em></p> Neng Tanty Sofyana Redoyan Refli Copyright (c) 2024 Journal of Tropical Upland Resources (J.
