Abstract

The study aimed to determine the agronomic characteristics of 14 local upland rice varieties from Bengkulu. The study used a randomized block design (RBD) with one factor, namely 14 local upland rice varieties, and six replications. It's varieties was G1; Keleng Mano, G2; Masak Berangin, G3; Tambun Buih, G4; Sebakas, G5; Ogan, G6; Siung Kancil, G7; Sirantau, G8; Abang Pintal, G9; Babatan, G10; Komering, G11; Lampung, G12; Ir 64, G13; Sawah Darat, and G14; Umbul-umbul. The results concluded that there is agronomic diversity among the 14 local upland rice varieties from Bengkulu. The highest plant height ranged between 131 – 152 cm and was not significantly different shown in the varieties of Ogan 146.83 cm, Sirantau, Keleng Mano, Masak Berangin, Siung Kancil, Tambun Buih, Abang Pintal, Babatan, Sebakas, Komering, Lampung respectively and the lowest plant height ranged between 88 - 96 cm in the Sawah Darat, Umbul-umbul and IR 64 varieties with a height of 87.87 cm. The highest total number of tillers ranged between 15.5 – 18.5 tillers in the Sirantau variety but was not significantly different from the varieties of Ogan, Siung Kancil, IR 64, Tambun buih, Sebakas, Babatan and Lampung while the lowest number of tillers was in the Sawah Darat variety. The highest number of productive tillers ranged from 7.5 to 9.5 for the Sirantau, Komering, Ogan, Siung Kancil, IR 64, Sebakas, Tambun Buih, Lampung, Babatan, and Abang Pintal varieties. The lowest number of productive tillers ranged from 6.3 to 6.8 for the Masak Angin, Sawah Darat, Umbul-umbul, and Keleng Mano varieties. The fastest flowering time ranged from 78 to 90 days and was not significantly different for the IR 64, Umbul-umbul, Komering Lampung, and Sawah Darat varieties.

Review

This study presents a timely and relevant evaluation of 14 local upland rice varieties from Bengkulu, addressing a crucial need for characterization of indigenous germplasm. The objective to determine the agronomic characteristics is well-defined, and the chosen methodology, a Randomized Block Design with six replications, is appropriate for robust data collection in agricultural field trials. The inclusion of a diverse range of local varieties, alongside a comparative variety like IR 64, provides a solid framework for assessing the genetic resources available in the region. This foundational work is essential for conservation efforts and future breeding initiatives. The research successfully identified significant agronomic diversity among the 14 local upland rice varieties, which is a key finding. Important variations were observed across several critical traits. Plant height showed a broad spectrum, from tall varieties like Ogan (146.83 cm) and others, to shorter types such as Sawah Darat, Umbul-umbul, and IR 64 (87.87 cm). Tiller production also varied considerably, with Sirantau consistently demonstrating high total and productive tillers, indicating its potential for higher yields. Differences in flowering time, ranging from 78 to 90 days for the fastest varieties, are also noteworthy for adaptability to different cropping calendars and environmental conditions within the region. The findings have significant implications for agricultural development and plant breeding in Bengkulu. The identified superior varieties for specific traits, such as Sirantau and Ogan for tillering capacity, offer valuable candidates for direct release to farmers or as parental lines in breeding programs. Conversely, varieties with early flowering times could be beneficial for areas prone to drought or with shorter growing seasons. This study not only highlights the richness of Bengkulu's upland rice genetic diversity but also provides a strong basis for further research, including more detailed physiological or molecular characterization, and multi-location trials to evaluate yield stability and adaptability across different environments.
