【 摘 要 】

Armyworm is important polyphagous pest causing economic losses in many agricultural crops including soybean. In Indonesia, there are no soybean varieties which indicated had a resistance against armyworm. The experiment was conducted in Laboratory of Entomology and Green House of Indonesian Legumes and Tuber Crops Research Institute from March to April 2016. The experiment was arranged using randomized block design with a total of 18 soybean genotypes as a treatment in three replicates. The results showed that the difference of soybean genotypes had a significant effect on the leaf damaged intensity. Based on no-choice test and the leaves damaged intensity compared with resistant check genotypes, there was no genotype indicated resistant against S. litura. Most of the tested genotype showed moderately resistant and others showed susceptible to highly susceptible. Genotypes that indicated as moderately resistant are G 511 H/Anjs-1-1, G 511 H/Arg//Arg///Arg-30-7, G 511 H/Kaba//Kaba///-4-4, G 511 H/Kaba//Kaba///Kaba////Kaba-16-2, G 511 H/Anjs/Anjs///Anjs-3-3, G 511 H/Anjs/Anjs-1-2, G 511 H/Anjs/Anjs-5-5, G 511 H/Anjs/Anjs///Anjs-6-11, and Argomulyo. In conclusion, those nine genotypes indicated have antixenosis resistance against armyworm and can be considered as a source of gene for improving the soybean resistance to armyworm.
