Abstract

Rust disease is an important disease on soybean, it was widely distributed in almost all soybean
producing countries, the yield losses can be reach 85 %. One of the control measured is planting the
resistant varieties. Resistant gens of one character can be obtained from the germplasm collection. The
study aiar to evaluate the resistance of soybean germplasm collection against rust diseases. The study was
conducted at Kendalpayak experimental station, Indonesian Legumes and Tuber Crops Research
Institute, in June to September 2013. Materials used were 175 genotypes of soybean germplasm collection.
Observations of rust disease resistance based on the method of International Working Group on Soybean
Rust system. The results showed that out of 175 soybean genotypes tested, 162 genotypes were moderately
resistant, 12 genotypes were moderately susceptible , and one genotype was susceptible to rust disease.
Keywords: soybean , rust disease, resistance.
