This reserach aimed to identify the morphological chracteristics and phylogenetic relationship of Dragon Fruit (Hylocereus sp.) plants. The research was started from April 2017 until May 2017 at Sitinjo district of Dairi Regency North Sumatera with survey methode using dragon fruit descriptor of Hylocereus by International Union For The Protection Of New Varieties (UPOV). Sampling technique using purposive sampling. Exploration results was obtained 24 genotypes of Dragon Fruit plants based on identified fruit morphological characteristic. Based on clustering analyze the closest genetic relationship is on genotype G17 and G23 which has 2 differences of 7 characteristic with dissimilarity coeficient is 1,000 and the furthest genetic relationship is on genotype G18 and G26 with dissimilarity coeficien is 4,796 which has 5 differences of 7 characteristic.

The purpose of this research is to identification of morphological characteristic and kinship of sweet potato at Kabupaten Simalungun and Kabupaten Dairi. The research well done in regency Simalungun dan regency Dairi, North Sumatera at March to June 2017 with descriptive survey using characterzed based on International Board for Plant Genetic Resources (IBPGR) standard and purposive random sampling technique. The result of this research indicate there 21 (twenty one) genotype of sweet potato that in Kabupaten Simalungun consists of Kecamatan Silimakuta (G1, G2, G3, and G4), Purba (G5, G6 and G7), Dolok Silau (G8), Pamatang Silimahuta (G9), Dolok Perdamean (G10), Hutabayu Raja (G11) in Kabupaten Dairi consists of Kecamatan Parbuluan (G12, G13, G14, G15, and G16), Sidikalang (G17 and G18), Sumbul (G19 and G20), and Sitinjo (G21) with closest kinship is G18 and G20 with a coefecient similarity 8,541 and farthes kinship is G4 and G5with a coefecient similarity 116,338.

Characteristics of several varieties of soybean (Glycine max L. Merrill) with giving BAP and GA3 on flooded lisna dewita lumban gaol; Revandy Iskandar Muda Damanik; Eva Sartini Bayu Girsang

This research aim to know the characteristic of some varieties of soybean with giving BAP and GA3 on flooded. The research was conducted at Land Faculty of Agriculture, University of Sumatra Utara, Medan, Indonesia with altitude ± 25 meters in April 2017 until August 2017 using a randomized block design (RAK) with three factors, i. e : varieties (Grobogan, Argomulyo and Demas 1),hormone BAP and GA3 (0 ppm, BAP 30 ppm + GA3 100 ppm, BAP 60 ppm + GA3 200 ppm, and flooding (control and waterlogged. The parameters observed were plant height, leaf number, root volume, number of plants pods, number of seeds of crop, protein totale, chlorophyll totale, and analysis of super oxide dismutase enzymes. The results showed that varieties significantly affect plant height 2, 3, 5 MST, leaf number 3, 4 MST, root volume, number of plant pods and number of seeds of crop. Hormone treatment significantly affected plant height 2, 3, 4 MST, and root volume. flooding significantly affect chlorophyll analysis.number of plants pods and number of seeds of crop. Interaction varieties and hormone significantly affected plant height 2, 3 MST, leaf number 4 MST and root volume. Interaction varieties and flooding significantly affect root volume. Interaction between varieties, ZPT and flooding significantly affect the root volume.

Adaptasi Tanaman Ubijalar ( Ipomoea batatas L.) Dataran Tinggi pada Dataran Rendah Hermanto Panjaitan; Emmy Harso Kardhinata; Revandy Iskandar Damanik

ABSTRAKSebanyak 5 genotipe ubijalar (G1, G2, G3, G4, G5) dataran tinggi ditanam pada dataran rendah. Penelitian ini bertujuan untuk mengetahui adaptasi tanaman ubijalar (Ipomoea batatas L.) dataran tinggi pada dataran rendah. Penelitian dilaksanakan di Tanjung Selamat Kabupaten Deli Serdang mulai bulan Mei sampai dengan Oktober 2017. Rancangan yang digunakan pada penelitian ini adalah rancangan acak kelompok. Hasil penelitian ini menunjukkan ubijalar G4 memiliki bobot umbi paling berat jika dibandingkan dengan genotip lainnya (466,67 g). G3 memiliki jumlah umbi paling banyak jika dibandingkan dengan genotip lainnya (4,67). G1 memiliki rataan bobot umbi paling berat jika dibandingkan dengan genotip lainnya (197,81 g). G1 dan G2 memiliki ketebalan korteks paling tebal jika dibandingkan dengan genotip lainnya (9 atau sangat tebal). Ubijalar dataran tinggi yang ditanam pada dataran tinggi lebih mudah beradaptasi dibandingkan yang ditanam pada dataran rendah. Dapat dilihat dari semua parameter produksi yang diamati.Kata kunci : adaptasi, genotip, karakter morfologis, ubijalar
