“…Masalah yang dihadapi adalah belum tersedia informasi parameter genetik dari plasma nutfah ini seperti variabilitas genetik, heretabilitas, korelasi dan pengaruh langsung dari karakter-karakter yang erat hubungannya dengan hasil (BOROJEVIC, 1990dalam WAHYUNI et al, 2004. Menurut FREY (1983) dalam WAHYUNI et al (2004) pemuliaan tanaman meliputi 3 fase kegiatan, yaitu: (a) menciptakan variabilitas genotip dalam suatu populasi tanaman, (b) seleksi genotip gen-gen pengendali karakter yang diinginkan, dan (c) melepas kultivar terbaik untuk produksi pertanian.…”

ABSTRAK Analisis jarak genetik dilakukan terhadap tujuh populasi pinang (Areca catechu L.), yaitu Sumut-1, Sumut-2, Sumbar-1, Sumbar-2, Sumbar-3, Bengkulu-1 dan Bengkulu-2 hasil eksplorasi pada tahun 1994 dan telah dikoleksi di kebun koleksi plasma nutfah palma Kayuwatu, Sulawesi Utara. Tujuan analisis adalah untuk mengetahui seberapa besar jarak genetik antara ke tujuh aksesi pinang sekaligus untuk mengelompokkan ketujuh aksesi tersebut. Analisis menggunakan Uji Statistik D 2 dari Mahalanobis, sedangkan untuk pengelompokan populasi menggunakan metode Tocher yang dikemukakan oleh RAO dalam SINGH dan CHAUDARY. Hasil analisis menunjukkan bahwa ketujuh aksesi pinang membentuk 4 kelompok yaitu, kelompok I terdiri dari aksesi Sumbar-1 dan Sumut-1; kelompok II terdiri dari 3 aksesi yaitu Sumbar-3, Sumut-2 dan Bengkulu-1; kelompok III dan kelompok IV masing-masing hanya terdapat satu aksesi yaitu Sumbar-2 dan Bengkulu-2. Jarak genetik paling jauh adalah antara kelompok I dan II dengan nilai D 2 = 1263.137. Sementara jarak genetik antar kelompok terdekat adalah antara kelompok I dan III dengan nilai D 2 = 108.587. Penyumbang terbesar terjadinya pengelompokan tersebut adalah karakter jumlah bekas daun. Kata kunci : Pinang, Areca catechu L., populasi, jarak genetik, Sulawesi Utara ABSTRACT Genetic diversity of seven arecanut (Areca catechu L.) accessions from Sumatera Island Genetic divergence analysis has been done on seven arecanut (Areca catechu L.) populations, i.e, Sumut-1, Sumut-2, Sumbar-1, Sumbar-2, Sumbar-3, Bengkulu-1, and Bengkulu-2 explorated in 1994 and had been collected in Kayuwatu Experimental Garden, North Sulawesi. The purpose of the analysis was to know how far the genetic distance among the seven accessions of the arecanut. The analysis used D 2 statistics of Mahalanobis, while to cluster the population used Tocher Method by Rao. The result showed that there are four groups among the seven accessions of arecanut. Group I consisted of Sumbar-1 and Sumut-1, group II consisted of Sumbar-3, Sumut-2, and Bengkulu-1, and both of group III and group IV consisted of one accession, namely Sumbar-2 and Bengkulu- 2 respectively. The largest genetic distance occurred between group I and group II (D 2 = 1263.137) while the smallest genetic distance occurred between group I and group III (D 2 = 108.587). Number of leaf scars was the largest contribution of the grouping. Key words : Arecanut, Areca catehcu L., population, genetic distance, North Sulawesi

“…Also, according to Sulastri (2010), head weight is influenced by how much photosynthetic results are distributed to the crop area. This statement was also expressed by Wahyuni et al (2004) that crop yield does not depend on how much photosynthate is given and produced but is also influenced by how much photosynthate is distributed to the plant parts.…”

Research on the effect of doses of cattle biourine on plant N levels and growth of cabbage (Brassica oleraceae, L) in lowland Ultisol was carried out by Desa Bakti in Marga Sakti Sebelat District, North Bengkulu Regency in October 2019 to January 2020. This study aimed to determine the dosage of cattle biourine optimal for N levels and cabbage growth in lowland ultisols. This study used a Randomized Complete Block Design (RCBD) of one factor consisting of 4 treatments and 4 replications, with the treatment dose 0 L ha-1, 1500 L ha-1, 3000 L ha-1, and 4500 L ha-1. Observation data were analyzed by Analysis of variance (ANOVA) at ? level of 5% with the Orthogonal Polynomial Test. The results of the study showed that the optimum dosage was not obtained on the variable N levels of plants and soil pH, but had a very significant effect on both of these variables. The optimum dosage obtained on the variable growth and yield of plants includes the optimum dose of 2250 L ha-1 biourine producing an average plant height of 36.14 cm age 45 dap, the optimum dose of 2200 L ha-1 of biourine produces an average plant height of 37.87 cm age 60 dap, optimum dose of biourine 1250 L ha-1 produces an average biomass fresh weigh 1.33 kg, the optimum dose of biourine 1666.67 L ha-1 produces an average head weight of 0.83 kg, and optimum dose of biourine 2000 L ha-1 produces average head diameter of 15.36 cm.

“…Variabilitas genetik menunjukkan kriteria keanekaragaman genetik. Variabilitas genetik yang luas merupakan salah satu syarat efektifnya program seleksi, dan seleksi suatu karakter yang diinginkan akan lebih berarti apabila karakter tersebut mudah diwariskan (Wahyuni et al, 2004). Penyebab variabilitas dapat dibedakan menjadi dua kategori, yaitu variabilitas yang disebabkan oleh lingkungan (variabilitas lingkungan) dan variabilitas yang disebabkan oleh sifat atau pewarisan genetik (variabilitas genetik) (Huda, 2008).…”

The crossing between Srikandi Putih corn varieties which have high production potential and protein content with local pulut corn which has high amylopectin levels is expected to produce superior offspring. This study aimed to determine the character of F1 and F2 results of crossing of Srikandi Putih variety with local Pulut corn (waxy corn) at different planting distance. This research was conducted in the Experimental Farm of the Bajeng Cereals Crop Research Institute, South Sulawesi Province, from May-August 2018. This method used was Split Plot Design, consisting of Main Plots, namely planting distance (70 cm x 20 cm and 70 cm x 30 cm) and Sub Plots, namely Varieties (Srikandi Putih, Local Pulut, F1 and F2). The results showed that genotype significantly affected plant height, seed production per hectare, amylopectin content and seed protein content, and genotype had very significant effect on number of leaves, ear length, ear diameter, seed weight per plant and seed weight per plot. Planting distance has a very significant effect on seed weight per plot and the best was 70 cm x 20 cm. This is due to the number of populations at 70 cm x 20 cm planting distance more than 70 cm x 30 cm. Genotype interaction and planting distance have a very significant effect on seed weight per plant. Srikandi Putih variety was the best genotype for growth, production and protein content parameters while the best amylopectin content parameter was local Pulut. Srikandi Putih variety was potential for growth and production as well as high protein content, but low amylopectin levels while local Pulut has high potential for amylopectin levels but low growth and production potential. The best combination of growth, production, protein and amylopectin content was in F1 and F2 genotypes.
