Javanese cardamom plants are mostly propagated vegetatively using its rhizome. Therefore, the genetic variability is quite low so that needs to be enhanced, one of them by gamma irradiation. The objectives were reveal optimal dose (LD20 and LD50) irradiation on Java seedlings assess performance post experiment was arranged in randomized complete block design with 6 replications. Gamma ray used 0, 25, 50, 75, 100, 125, 150, 175, 200, 225, 250, 275 300 Gy. Survival rate, quantitative qualitative observation plant growth conducted. Irradiation conducted mature plant. Result showed LD20 LD50 values 55,89 Gy 100,75 Seedling necrosis leaves stem area after especially high doses. Until 25 weeks irradiation, irradiated 50 100 produced 16.7% new shoots, but their development very slow. Control 5.2 shoots good agronomic appearance 67% flowers at Furthermore, for cultivation optimized range 50-100 younger material. ABSTRAK Tanaman kapulaga jawa sebagian besar diperbanyak secara vegetatif dengan menggunakan rimpangnya. Oleh karena itu, variabilitas genetiknya cukup rendah sehingga tersebut perlu ditingkatkan, salah satunya iradiasi sinar gamma. Penelitian ini bertujuan untuk mengetahui dosis dan pada bibit Jawa menilai keragaan pasca Percobaan rancangan kelompok lengkap teracak ulangan. Iradiasi digunakan adalah Tingkat kelangsungan hidup, pengamatan kuantitatif kualitatif pertumbuhan tanaman dilakukan. dilakukan dewasa. Hasil menunjukkan nilai sebesar Bibit nekrosis daun batang setelah penyinaran terutama tinggi. Sampai umur minggu (MSI), yang diiradiasi menghasilkan 16,7% tunas baru, namun perkembangannya sangat lambat. kontrol 5,2 baru penampilan agronomis baik bunga iradiasi. Selanjutnya budidaya dioptimalkan kisaran bahan lebih muda.
