Abstract
<p>Soybean pod damaged by pod sucking bug (<em>Riptortus linearis</em>) is one of the constraint within soybean yield improvement in Indonesia. The research aimed was to identify the resistance of soybean genotypes to pod sucking pest. The experiment was conducted in Iletri’s screen house from March to June 2015. The experiment was arranged in Randomized Completely Block Design using 10 soybean genotypes with three replicates. The soybean resistance was evaluated using no-choice test. Data collected on number of pod/plant, number of seed/plant, seed weight per plant, number of attacked pod/plant, and number of attacked seed/plant. The result showed that the lowest percentage both of pod and seed damage was G511H/Anjasmoro//Anjasmoro-2-8, that was 25.83 % and 19.12 %, respectively. Based on the value of the percentage of seed damage, there were five susceptible genotypes, three moderately resistant, and two resistant genotypes. Based on the value of the percentage of pod damage, showed four susceptible genotypes, five moderately resistant, and a resistant genotype. G511H/Anjasmoro//Anjasmoro-2-8 was the only resistant genotype, and it could be used as a genetic source in the improvement of soybean resistance to pod sucking bug.</p><p><strong>How to Cite</strong></p><p>Krisnawati, A., Bayu, M.

Summary
The largest soybean cultivation areas in Indonesia are in the dry season. The abundant light and relatively stable of high temperatures in the dry season causes high infestation of pests in soybean. Pod sucking bug is a major pest in soybean production areas in Indonesia. This pest has spread over almost all provinces in Indonesia and cause considerably yield losses both in soybean quality and quantity. Pod sucking bug has the most extensive spread area and attacks compared to other soybean pests. Other studies have revealed that the pod sucking attack on pod maturity phase causes increased seed damage which resulting in delayed maturity (Leonard et al, 2011). The accumulation of losses caused by the pod sucking pest infestations may decreased soybean yield up to 79% (Arifin & Tengkano, 2008), and can result in crop failure if it is not well controlled (Marwoto, 2007). The research aimed was to identify the resistance of soybean genotypes to pod sucking pest (Riptortus linearis) using no-choice test
