Variables observed included: plant height, stem diameter and number of leaves. Data were analyzed using analysis of variance and the Least Significant Difference Test (LSD) 5%.The results of research on the germination of jackfruit seeds in the zygote seed treatment (Z1), 2 whole and 2 split polyembryonic seeds had a viability above 80%, so they could be used as a seed source. Keywords: Jackfruit, Polyembryony, Seed Production  Abstrak Tujuan penelitian ini mengetahui sifat-sifat poliembrioni pada biji nangka apakah hasil biji poliembrioni yang dihasilkan dapat dijadikan sebagai penyumbang untuk produksi benih, mengetahui jumlah bibit yang dihasilkan dari sifat embrioni serta mengetahui hubungan antara poliembrioni dengan pertumbuhan bibit. Penelitian  mengunakan rancangan Acak Kelompok (RAK) dengan 5 perlakuan   masing-masing : benih Zigotik nangka utuh 1 (Z1), benih Poliembrioni nangka  utuh 2 (PU2), benih poliembrioni nangka utuh 3 (PU3), benih poliembrioni nangka belah 2 (PB2) dan benih poliembrioni nangka  belah 3 (PB3) Variabel yang diamati, meliputi: tinggi tanaman, diameter batang dan  dan jumlah  daun. Data  dianalisis menggunakan  analisis ragam dan Uji Beda Nyata Terkecil (BNT) 5 %. Hasil penelitian  perkecambahan  benih nangka  pada perlakuan  benih zigot (Z1), benih poliembrioni  utuh 2 dan belah 2  mempunyai viabilitas diatas 80%, sehingga dapat dijadikan sebagai sumber benih.
