Genotypic Selection

Genotypic selection on red chili palnts resistant to anthracnose disease at m2 generation. A superior anthracnose resistant cultivar was sought to overcome the low production due to anthracnose in red chili. For the development of superior cultivars, it was necessary to select genotypes that were resistant to anthracnose. Selection effectiveness was determined by wide diversity and high reliability. The purpose of this study was to see the diversity and heritability of agronomic characters and resistance to anthracnose on chili plants, and to select genotypes that were resistant to anthracnose. This research was conducted with a design without repetition. The plant material used was the seed of the results of gamma ray mutations in generation M2. The results of this study were: the broad diversity of phenotypes found in all characters observed, while all characters of the genotype observed had broad criteria except plant height at flowering and harvest, and at seedling period. The genotype that should be planted in the next generation was genotype number 136. Genotype number 136 was very resistant to anthracnose infection.

Anther culture technique is able to accelerate plant breeding activities. The objectives of this research was to determine the agronomic traits that could be used for selection of the dihaploid rice line population through the calculation of heritability, genotypic correlation, path analysis and selecting dihaploid rice lines. The plant material used was 65 dihaploid rice lines DH 1 of F1 anther culture plants and Ciherang and Inpari 13 as check varieties. Agronomic characters that could be used as selection character are generative plant height, number of filled grain per panicle, the total number of grains per panicle, weight of 1,000 grains, and grain per hill. Twenty three dihaploid lines were selected based good agronomic characters with criteria generative plant height between 80-120 cm, number of filled grains per panicle > 100, number of grains per panicle > 120, weight of 1,000 grains > 20 g, and grain per hill > 25 g.Keywords: anther culture, heritability, agronomic characters

ABSTRACTVariability of mutant genotypes chrysanthemum (Dendranthema grandiflora Tzvelv.) fifth generationsthrough gamma iIrradiationDendranthema grandiflorum Tzvelv. is a major floriculture in Indonesia, and it is one of the five most popular flowers in Indonesia. Chrysanthemum varieties in Indonesia is largely the introduced varieties. Chrysanthemum hybridization especially for decorative flower type in order to obtain superior varieties is relatively difficult, so the mutation breeding is one approach that can be taken to get the chrysanthemum varieties with different phenotypic performances with the that parent.The purpose of this study was to obtain information genetic and phenotypic variability characters observed on chrysanthemum irradiated with gamma ray. The experiment was conducted by an experimental method using a randomized block design (RBD). The treatments consisted of 37 mutants genotypes and 11 genotypes chrysanthemums parent as controls with two replications. The results of this study indicated that the genotypes tested had broad genetic and phenotipic variation for the plant height, flower diameter, number of flower and neck lengths.Key words: Chrysanthemum mutants, Variability, Gamma ray irradiation.ABSTRAKKrisan merupakan komoditas tanaman hias utama di Indonesia dan paling banyak diminati masyarakat. Varietas-varietas krisan yang beredar di Indonesia sebagian besar merupakan varietas introduksi. Persilangan krisan khususnya untuk tipe bunga dekoratif dalam rangka memperoleh varietas unggul relatif sulit dilakukan, sehingga pemuliaan mutasi merupakan salah satu pendekatan yang dapat ditempuh untuk mendapatkan varietas krisan dengan penampilan fenotipik yang berbeda dengan induknya. Tujuan penelitian ini adalah untuk mendapatkan informasi variabilitas genetik dan fenotipik karakter-karakter yang diamati pada tanaman krisan yangd iradiasi dengan sinar gamma. Percobaan dilakukan dengan metode eksperimen menggunakan Rancangan Acak Kelompok (RAK). Perlakuan terdiri atas 37 genotipe mutan krisan dan 11 genotipe tetua krisan sebagai kontrol dengan dua ulangan. Hasil penelitian menunjukkan bahwa genotipe-genotipe yang diuji memiliki variabilitas yang luas untuk karakter tinggi tanaman, diameter bunga, jumlah kuntum dan panjang tangkai bunga.Kata kunci: Mutan krisan, Variabilitas, Sinar gamma

Generation Sequencing

In era of sequencing revolution, scientists seek for knowledge about the ever-expanding field of technology, Next Generation Sequence (NGS) to be applied in their research due to its high reliability and rate of discovery. What is NGS? To obtain a detailed understanding about NGS, it is required to look back the history of sequencing and how the NGS stepped into life science. This review paper gives an overview of NGS projects in wild terrestrial vertebrate including applications such as whole genome sequencing and metagenomics.

SUMMARYEffects of simulated and actual grazing at the tillering stage on tiller production and other agronomic characters were studied over a number of seasons at two sites in northern Syria with two local barley landraces. In general, grazing encouraged tiller production but reduced head number per unit area because of a higher tiller mortality or infertility. Seed number per head and seed weight were not affected by grazing except in one season. Grazing delayed heading and maturity and reduced plant height. Simulated and actual grazing produced similar effects on the different characters investigated.
