  • Descrição: Soybean cultivar with high pod-shatter resistance and good agronomic performances is essential for reducing yield loss in soybeans. The research aimed to evaluate the pod-shattering resistance and agronomic performance of soybean genotypes in the dry season. The experimental research was conducted in Probolinggo, East Java, Indonesia, from March to June 2019. The experiment used 150 genotypes and laid in a randomized block design with three replicates. Three sample plants were randomly taken after the R8 phase, and thirty pods were randomly taken for shattering evaluation using the sun-drying method. The result showed that the dry environment exacerbated the increase in pod shattering in soybeans climate. The screening for pod-shattering using the sun-drying method on the first day showed that 17 genotypes were resistant to pod-shattering, and 46 were resistant. The third day of sun drying revealed no very resistant genotype. On the fourth day of screening, it obtained six resistant genotypes (Anjas/IAC 100-1-183, Grobogan/G100H-8-342, Mahameru/IAC100-3-427, Mahameru/IAC100-3-937, G100H/Anjasmoro-3-181, and Mahameru/IAC100-2-426). Harvesting could be delayed by 4-5 days for resistant or very resistant genotypes in the dry season or dry climate environment. The number of nodes, number of branches, and number of filled pods were all significantly positively correlated with seed yield. The plant height has a significant positive correlation with the number of nodes and the number of filled pods. The GYT-biplot indicates two genotypes with the best performance for YLD*PS (Mahameru/IAC100-2-426 and Mahameru/IAC100-3-427).
