Agronomic performance of F7 soybean lines resistant to Soybean mosaic virus in the dryland area

Abstract

Abstract In Indonesia, soybean cultivation is generally planted in paddy fields after the rice harvest. However, expanding soybean cultivation is needed to make optimal dry land in the future. This study aims to obtain F7 soybean lines resistant to Soybean mosaic virus (SMV) adaptive in the dry land. In the dry land planted eleven soybean breeding lines resistant to SMV and two varieties as control. Ten days after planting (DAP), soybean plants were inoculated with SMV. The experiment was conducted in the randomized complete block design with four replicates within each area. These results showed that the GK/PI200.485-7-17 line was the most superior soybean line and the potency to develop in the dryland area because it had the highest number of branches per plant, number of filled pods per plant, and 100-seed weight. The tested line showed the highest seed yields of 2.40 t/ha, and 2.72 t/ha, in Girisubo and Sidowayah Districts, respectively. This line did not indicate any serological relationship to SMV in both locations.
