The research was aimed to know the characteristics of vegetative and generative of introduction and
some local maize varieties. The research was carried out on the land of the Centre Seed Service of
Cash Crops, Departmentof Agriculture, Medan Sunggal, Deli Serdang district, from July 2016 to
October 2016. The randomized block design was used with three varieties of maize (Black Aztec,
Bisi2, Bonanza). Variables observed were: the plant height, the time of flowering, the time of
female flowers bloomed, the time of harvested, the cob length, the number of lines per cob, the
production per sample plant, the production per plot. The results showed that the three varieties of
maize tested have varying diversity to the plant height, the time of male flower bloomed, the time of
harveste, the cob length, the number of line per cob, the production per sample, the production per
plot. The Black Aztec showed the lowest production (1005.56 grams per plot) mean while the
Bonanza showed the highest production (2338.44 grams). The highest heritability and the broad of
diversity coefficient were obtained in the time of male flower bloomed, the time of female flower
bloomed, the time of harvested, the number of lines per cob.
Penelitian ini bertujuan untuk mengetahui karakteristik vegetatif dan generatif jagung introduksi dan beberapa varietas jagung lokal. Penelitian dilaksanakan di UPT Balai Benih Induk (BBI) Palawija Dinas Pertanian Tanjung Selamat, Kecamatan Medan Sunggal, Kabupaten Deli Serdang Medan pada Bulan Juli sampai Oktober 2016. Penelitian ini menggunakan rancangan acak kelompok dengan tiga jenis jagung yaitu Jagung hitam, varietas Bisi 2 dan Varietas Bonanza sebagai faktor penelitian. Peubah amatan yaitu tinggi tanaman, umur berbunga jantan, umur berbunga betina, umur panen, panjang tongkol, jumlah baris per tongkol, produksi per tanaman sampel, produksi per plot. Hasil penelitian menunjukkan ketiga varietas jagung yang diuji memiliki keragaman yang bervariasi terhadap tinggi tanaman, umur keluar bunga jantan, umur keluar bunga betina, umur panen, panjang tongkol, jumlah baris per tongkol, produksi per sampel dan produksi per plot. Jagung hitam memiliki produksi terendah dengan produksi 1005.56 g per plot dan jagung Varietas Bonanza memiliki produksi tertinggi dengan produksi 2338.44 g per plot. Karakter umur keluar bunga jantan, umur keluar bunga betina, umur panen dan jumlah baris per tongkol memiliki nilai heritabilitas yang tinggi dan diikuti koefisien keragaman yang luas.
