Soybean development in dry land during the rainy season not only contributes to soybean production but also has the potential to be a source of seeds. The research aimed to identify the yield and yield component performance of soybean promising line at upland in the rainy season. A total of fourteen soybean promising lines and two check cultivars were evaluated for their yield and yield components in Blitar and Malang. The field experiments were conducted in each location during the rainy season 2021 using a randomized block design with four replicates. A significant GEI was found on the plant height, number of branches/plant, number of nodes/plant, number of filled pods/plant, and 100 seed weight. The Blitar location indicated resulting in the optimum yield and yield components of the tested promising lines. The average yield in Blitar was 2.81 t/ha (an average of 2.07 – 3.60 t/ha) and in Malang was 2.16 t/ha (an average of 1.52 – 3.18 t/ha). The number of branches and number of nodes has significant roles in determining the seed yield in soybean. Two genotypes with consistently high yield in Blitar and Malang are recommended to be evaluated in further advanced yield trials in different environments.
