Characterization of adaptive and productive soybean (G. max L.) genotypes in dry land of Kalimantan, Indonesia

Abstract

Dry land is one of potential areas for soybean (Glycine max L. Merrill) development. A total of 12 soybean genotypes, including two check varieties of Anjasmoro (high yield) and Demas 1 (adaptive in acidic dry land) were evaluated in two locations of dry land in Gunung Makmur Village and Kuala Tambangan Village, South Kalimantan, Indonesia from May to August 2017. The experimental design in each location was randomized block design (with 12 soybean genotypes as treatments) and four replicates. Data were subjected to combined ANOVA. The range of seed yield in Gunung Makmur was 1.56 t ha-1 to 3.18 t hm-2 and in Kuala Tambangan was 1.72 t ha1 to 2.96 t ha-1. Anjasmoro variety showed a higher productivity than Demas 1. Genotype of 19BE produced the highest yield in Gunung Makmur (3.18 t ha-1), meawhile G511H/Anjs-1-3 produced the highest yield in Kuala Tambangan (2.96 t ha-1). The best genotype across environments was G511H/Anjs-1-3 (2.99 t ha-1), then followed by 19BE (2.74 t ha-1). The G511H/Anjs-1-3 has medium height and a relatively low of empty pods, meanwhile 19BE has medium height and relatively high numbers of nodes per plant and branches per plant. Those genotypes could be developed in acidic dry land area of Kalimantan.
