M3 generation population was thought to have wide character variability. The objective of this study was to determine the performance of agronomic characters and to estimate genetic parameters values of M3 generation in mutant populations of 150 Gy and 450 Gy. Seeds from mutant population 150 Gy and 450 Gy in M2 generation were harvested, and then their seeds were grown as M3 generation. Variations that were obtained of each character at generation M3 influences plants growth and development. The difference in character variability from the two mutant putative populations causes significant differences compared to the mean value character of control plants population. The heritability values of all characters observed range from low to high. Character canopy diameter and number of fruits per plant can be used as a character of selection in the next generation

Permata and Tymoti), and the second was concentration of Oryzalin (0 µM as control, 30 µM, 60 µM, 90 µM and 120 µM). Parameters observed 30 days after sowing were the plant height, leaf number and the stem diameter of both tomato varieties. The results showed that there was no variation between var. Permata and Tymoti in parameters observed. However, there were differences among plants growth treated plants by Oryzalin concentration. In general, the higher the concentration of oryzalin, the shorter the plant height, the fewer leaf number and the smaller stem diameter for both tomato varieties.

Nowadays, people's need for soybeans is not only seen from the production aspects but also soybean nutrient contents, especially fatty acids. One of the ways to develop superior varieties of soybean with high fatty acids is through mutations. Seven soybean mutants selected M5 and M7 generation with high production character and resistance Athelia rolfsii Curz were genetically related to high fatty acids using SSR markers. DNA quality and quantity test results showed DNA purity between 1.12-2.13 with concentration between 15.4-97.9 μg/mL. The FAD2-2D locus is the gene candidate of the result by the QTL mapping used in this study to identify soybean genes related to linoleic acid characters. The results showed that the primer used was specific and polymorphic. Mutant soybeans tested have a high genetic diversity.

The aims of research was to study the response and heritability of oil palm type of seedling K++ and K-- to KCl fertilizer application in pre nursery. This research was conducted at PT. Socfindo Bangun Bandar, Martebing Village, Dolok Masihul District, Serdang Bedagai Regency, Province of North Sumatera, with an altitude of ±60 meters above sea level, starting from February 2017 until May 2017 using Randomized Block Design with 2 factors of treatment: seed type (K++ and K--) and aplication of KCl fertilizer (0 g, 0.15 g and 0.30 g)/seedlings. The data obtained were analyzed using a verbal examination and continued by Duncan's multiple-range test. The parameters observed were plant height, stem diameter, number of leaves, the element of potassium nutrients on the soil and the element of potassium nutrient in th...

The research was conducted at Desa Tanjung Selamat, Kecamatan Sunggal, Kabupaten Deli Serdang from July to December 2016. The research was arranged by Randomized Block Design for one variety (Adira-1) and 6 genotype (Valencia, Malang, Malaysia, Lampung, and Putih) each treatment was replicated 4 t imes.The result showed that Pulut genotype has the highest average plant heigth (277,48 cm) that is significantly different from the others accept Malang genotype, Malang genotype has the highest average diameter (31,26 mm) wich is significantly different from the others. The highest Lobus length character is at Pulut genotype (22,6 cm) and the highest lobus wide is at Malang genotype (7,3 cm). The highest leaf length petiole character is at Putih genotype (31,4 cm), and the highest of leaf lobus character at Adira 1 and Lampung genotype are 5 leaves lobus. There are was differe...

The gamma irradiation was used toinduced the mutation as the genetic diversity. The increase of the genetic diversity would make theeasy selection of certain growth character. The effect of gamma irradiation on the first phase ofplant growth would affected the morphological performance and the plant yield. The aim of theresearch was to determine the morphological response of soybean plant (Glycine max (L.) Merill)Anjasmoro variety to the gamma irradiation. The research was priored by inducing the seed ofAnjasmoro variety with several gamma irradiation i.e. : 0, 100, 200, 300 gy. The result showed thatthe gamma irradiation affected the plant height, the number of branches, the time of flowering, theflower colouration, the time of pod maturation, the number of pods, the number of seeds, and theseed weight per plant.Keywords : Anjasmoro, Seeds, Gamma Ray Irradiation

Penelitian ini dilaksanakan di rumah kasa dan Laboratorium Kultur Jaringan, Fakultas Pertanian USU Medan,dari bulan Juni sampai November 2016. Penelitian dilakukan dengan cara perendaman bahan tanam setek secara keseluruhan dengan 4 konsentrasi yakni 0ppm, 2ppm, 4ppm dan 6ppm.Hasil penelitian menunjukkan tanaman Aglaonema hasil perlakuan kolkisin 6ppm berpengaruh sangat nyata pada peubah amatan panjang daun terpanjang. Hasil penelitian menunjukkan tanaman Aglaonema hasil perlakuan kolkisin memiliki karakter morfologis dan kromosom yang berbeda dibandingkan dengan kontrol. Karakter fenotipe paling baik dihasilkan pada dosis kolkisin 6ppm, dan perlakuan konsentrasi kolkisin mampu menghasilkan karakter fenotipe dan kromosom yang aneh dan berbeda.

Nowadays, people's need for soybeans is not only seen from the production aspects but also soybean nutrient contents, especially fatty acids. One of the ways to develop superior varieties of soybean with high fatty acids is through mutations. Seven soybean mutants selected M5 and M7 generation with high production character and resistance Athelia rolfsii Curz were genetically related to high fatty acids using SSR markers. DNA quality and quantity test results showed DNA purity between 1.12-2.13 with concentration between 15.4-97.9 μg/mL. The FAD2-2D locus is the gene candidate of the result by the QTL mapping used in this study to identify soybean genes related to linoleic acid characters. The results showed that the primer used was specific and polymorphic. Mutant soybeans tested have a high genetic diversity.

(Merrill) in M5 generation based on high production character and tolerance of stem rot disease Athelia rolfsii (Curzi). This research was conducted in Plant Disease Laboratory and experimental field Faculty of Agriculture Universitas Sumatera Utara Medan, Indonesia. This research was conducted from December 2016 to June 2017. The treatments were 15 mutant lines genotypes and Anjasmoro variety. The results showed that some lines mutant genotypes can gave the good agronomic appearance character than Anjasmoro variety on inoculation treatment of stem rot disease. Selection performed on population M 5 producesselected individuals with tolerance of stem rot disease from 100 and 200 Gy population.
