description: Abstrak    Pola segregasi karakter merupakan salah satu parameter genetik dalam proses  seleksi. Pemuliaan tanaman kedelai akan efektif apabila menggunakan pola  segregasi. Penelitian bertujuan untuk mengestimasi sebaran frekuensi, pola  segregasi, dan jumlah gen yang mengendalikan karakter agronomi tanaman  kedelai generasi F2 hasil persilangan Wilis x B3570. Penelitian dilaksanakan di  Kebun Percobaan dan Laboratorium Benih dan Pemuliaan Tanaman Universitas  Lampung pada Oktober 2011 sampai Februari 2012. Penelitian dilakukan dengan  rancangan percobaan tanpa ulangan dan analisis data menggunakan uji khikuadrat untuk kesesuaian distribusi normal dan kesesuaian antara nilai  pengamatan dan nilai harapan. Hasil penelitian menunjukkan sebaran frekuensi  karakter umur berbunga, tinggi tanaman, jumlah cabang produktif, bobot 100  butir, dan bobot biji per tanaman berdistribusi normal. Karakter-karakter tersebut  termasuk karakter kuantitatif yang dikendalikan oleh banyak gen. Karakter umur  panen dan jumlah polong per tanaman tidak berdistribusi normal. Karakterkarakter tersebut termasuk dalam karakter kualitatif yang dikendalikan oleh dua  gen. Karakter umur panen dikendalikan oleh dua gen yang bekerja secara  epistasis dominan duplikat dengan nisbah 15 : 1, karakter jumlah polong per  tanaman dikendalikan oleh dua gen duplikat yang bekerja secara epistasis dengan  efek kumulatif mengikuti nisbah 9 : 6 : 1 .  Kata kunci: Kedelai, Segregasi, Generasi F2                Abstract      Segregation pattern of characters is one of the genetic parameters in the selection  process. Soybean plant breeding will be effective when using patterns of  segregation. The research aimed to estimate the frequency distribution, patterns  of segregation, and the number of genes controlling agronomic characters of  soybean F2 generation from crosses Wilis x B3570. The research was conducted  at the Experimental Farm and Seed and Plant Breeding Laboratory of the  University of Lampung in October 2011 until February 2012. Research carried  out by the experimental design and data analysis without replicates using chisquare test for normal distribution and the suitability of the fit between the  observed values and the expected value. The results showed the character  frequency distribution flowering, plant height, number of productive branches,  weight of 100 grains, and grain weight per plant normally distributed. The  characters include a quantitative character controlled by many genes. Character  harvest and number of pods per plant was not normally distributed. The  characters are included in the qualitative character that is controlled by two genes.  Character harvest is controlled by two genes that duplicate dominant epistasis  working with the ratio 15: 1, number of pods per plant character is controlled by  two duplicate genes that work in epistasis with cumulative effect following the  ratio 9: 6: 1.  Key word : Soybean, Segregation, F2 generation.
