      Abstract
      Penelitian ini bertujuan untuk mempelajari respon pertumbuhan dan produksi 130 genotipe kedelai dari berbagai negara terhadap kondisi lingkungan tumbuh agroekosistem tropika basah. Percobaan ini disusun dengan rancangan augmented dalam rancangan acak lengkap (RAL). Benih kedelai yang digunakan sebagai pembanding (kontrol) adalah kedelai varietas Tanggamus, Anjasmoro, Argo Mulyo, Wilis dan Tachinagaha (varietas Jepang) yang terdiri dari 5 ulangan sehingga terdapat 150 satuan percobaan. Hasil penelitian menunjukkan bahwa genotipe GmWMC192 yang berasal dari Nepal berdaya hasil tinggi dan beradaptasi baik pada lahan kebun percobaan IPB Sawah Baru. Hal ini dilihat dari persentase tanaman yang tumbuh di lapangan, tinggi tanaman, jumlah buku, jumlah polong per tanaman, dan persentase biji penuh yang tinggi. Selain itu, genotipe GmWMC019 dan GmWMC042*2 yang berasal dari Korea Utara dan Republik Rakyat Cina berumur sangat genjah (66 hari) serta beradaptasi baik pada lahan kebun percobaan IPB Sawah baru. GmWMC019 dan GmWMC042*2 merupakan genotipe yang peka terhadap suhu tinggi
       
      This research aims to study the response of growth and production of 130 soybean genotypes from various countries to the condition at wet tropical agroecosystem. The experimental design used was augmented design in randomized complete design (RCB). Soybean seed that was used as check varieties are Tanggamus, Anjasmoro, Argo Mulyo, Wilis and Tachinagaha (Japan soybean variety) consist of 5 replicates so there are 150 units of the experiment. The results indicated that the genotype GmWMC192 from Nepal has high result and adaptable at the field of Bogor Agricultural University. It is seen from the percentage of the survived plants, plant height, the number of node, number of pods per plant, and higher percentage of full seeds. In addition, genotypes GmWMC042*2 and GmWMC019 from North Korea and China have very fast growth (66 days) and also adaptable at the field of Bogor Agricultural University. Both of the genotypes may be useful as a source in soybean breeding
