WIKA W SYAHPUTRI:Characteristics Study Of The Introduction And Some Local Corn Varieties. Supervised by HOT SETIADO and KHAIRUNNISA LUBIS.The difference in the character of corn plants at different age, would perform different growth, besides the genetic factors also influenced by thecultivation. The high genetic diversity was one of the important factors to produce the new superior varieties.The research was aimed to know the characteristics of vegetative and generative of introduction and some local corn 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 corn (Black Aztec, Bisi2, Bonanza).The data obtained were analyzed and continued with the DMRT. 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, the production per plot. The results showed that thevarieties significantly affected 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.Key words: introduction, maize, varieties

Publisher : Universitas Sumatera Utara

This research was conducted in Pembangunan street Subdistrict Medan Selayang, began from May to September 2016. This research used factorial randomized block design with two factors. The first factor was lady finger varieties were Red burgundy and Garibar. The second factor was application of organic fertilizer with four treatment (without organis fertilizer, compost 22,5g/10kg soil, vermicompost 30g/10kg soil, and chicken manure 75g/10kg soil). Garibar variety different on plant length, number of leaves, number of fruit, and fruit weight with Red burgundy. Chicken manure treatment can increase plant length, number of leaves, number of fruit, and fruit weight. Interaction between varieties and organic fertilizer treatment can increase plant length.

Elaeidobius kamerunicus introduced to Indonesia in Palm Research Center, Marihat. It is one pollinator to pollinate palm. Genetic changes in these insects cause a decline in palm oil production. The purpose of this study to determine the genetic diversity of it based molecular analysis techniques AFLP using three primers. Primers used are HEX (EcoR1 ACA - Mse1 CTT), FAM (EcoR1 AGG - Mse1 CAG) and FAM (EcoR1 AGG - Mse1 CTT). Analysis of genetic diversity using the MEGA program version 6. Phylogenetic tree using 'Neighbor-Joining Tree'. AFLP amplification product to 42 samples of genomic it and 3 Sitophilus oryzae genomic sample as a control showed a high diversity. The analysis showed that itgenetically grouped separately with S. oryzae. It contained in districts in North Sumatra has two large groups : group A1 and A2. Group A1 consisting of Ajamu, Bah Birong Ulu, Binanga, Bukit Sentang, Marihat, Padang Madarsah and PT. TPS Sibolga while the Group A2 consists of two regions, namely Marihat and Bah Birong Ulu while S. oryzae contained in Medan form their own group.
