Genetic Parameters of Soybean [Glycine max (L.)] Genotypes Tolerant to Salinity

Abstract

Background: Saline land can be used to increase soybean planting area. Adaptive varieties is one of technology to utilize saline land for soybeans. The objective of this study was to determine the phenotype and genotype performance of the F3 generation soybean lines in saline soil of Indonesia. Methods: A total 247 soybean genotypes, including four check varieties, were planted in augmented design in 2018. The field electrical conductivity (EC) value before planting soybean was 10.4 dS/m and soil acidity was 8.1 which was classified as high saline land based on Jones (2002). Result: The number of selected plants were 172 single plants. GH K13/Anjasmoro lines has an opportunity to further selection. Average height of GH K13/Anjasmoro selected lines was 26.4 cm, number of fertile nodes was 11, number of filled pods was 27 and seeds weight per plant was 4.8 g. GH K13/Anjasmoro lines has a high broad sense heritability for plant height, number of branches and number of filled pods, also high genetic advance for all characters.
