Ecuadorian potato landraces (Solanum tuberosum L.) are an important genetic resource, but they have been poorly described. Simple Sequence Repeats (SSR) markers were applied to 152 landraces to assess the genetic diversity of potatoes collected in three areas of high diversity: the Carchi, Chimborazo and Loja provinces. These SSR markers were previously used in the genotyping of more than 800 European potato varieties. The number of alleles and Polymorphism Information Content (PIC) of the markers found in this study were similar to those in European cultivars; however, the overlap in alleles was small. Based on SSR data, the relationship between local names of landraces and genetic identity showed several landraces with different names but identical molecular profiles. It also showed that landraces with identical names but obvious differences in tuber morphology were almost always genetically different. There was no clear grouping of material collected according to the regions under study that suggests extensive movement of seed potatoes all over Ecuador.

Qualitative Traits

Potato (Solanum tuberosum L.) is a versatile crop and a source of inexpensive energy in the human diet in many countries. It can be used as fresh products and commercially processed foods such as French fries and chips. Potato varieties development research previously conducted in Ethiopia related to processing quality were limited in their scope of quality parameters. This experiment was conducted at Holetta Agricultural Research Centre, Ethiopia during the main crop season of 2017. Twenty-four potato genotypes were evaluated for 23 quantitative and six qualitative traits in randomized complete block design with three replications to determining the nature and magnitude of common genetic diversity and to screen out genetically diverse parents by using cluster and principal component analysis. The first eight principal components accounted for 90.26% of the observed variations among 24 potato genotypes. The first three PC accounted for 60.43% of the variation. The genetic distances among the 24 potato genotypes ranged from 3.40 to 11.80 and the genotypes were grouped into eight clusters based on quantitative and qualitative traits. Cluster II consisted of 25%, Cluster IV, I, III contained 20.83%, 16.67% and 12.5% of genotypes, respectively, while Cluster VI, VII and VIII each consisted of one genotype. In conclusion, genotypes grouped under Cluster II and VIII worth further evaluation to obtain genotypes with highest total tuber yield, the specific gravity of tuber, dry matter content, total starch content, acceptable tuber physical and frying quality with other desirable traits.

Abstrak Pengembangan tanaman kentang (Solanum tuberosum L.)  unggul untuk menunjang kebutuhan produksi kentang yang terus meningkat membutuhkan tersedianya informasi genetik tanaman kentang yang ada. Informasi keragaman genetik dapat diperoleh menggunakan penanda molekuler RAPD yang dapat mendeteksi keragaman sampai pada tingkat DNA, baik pada daerah penyandi atau bukan penyandi protein dengan cara mendeteksi polimorfik sekuens nukleotida. Informasi yang diperoleh akurat karena tidak dipengaruhi lingkungan.  Penelitian ini bertujuan untuk menganalisis keragaman genetik dari kentang kultivar Superjhon, Atlantik, Dessire, Nadia dan Granola menggunakan penanda RAPD.  Hasil penelitian menunjukkan bahwa dari 14 primer acak yang digunakan hanya 7 yang memberikan pola pita DNA yang polimorfik dan 16 pita dari total 28 pita DNA yang dihasilkan (57 %)  merupakan pita DNA polimorfik. Rata-rata keragaman genetik kentang sebesar 26,8 %. Keragaman genetik terkecil (15,4 %) adalah antara kentang  Atlantic dan Superjhon, sedangkan keragaman terbesar (57,7 %) antara kentang Nadia dan Dessire. Hasil analisis pengelompokan menunjukkan tanaman mengelompok berdasarkan sifat/karakter dan asalnya. Kata kunci: kentang, keragaman genetik, RAPD Abstract The information of potato genetic diversity are required to support the increasing potato demands in the superior potato production. The information of genetic diversity can be obtained using RAPD molecular marker. RAPD can detect the genetic diversity at the DNA level, both in the coding region and non-protein-coding regions by detecting polymorphic sequences in nucleotides. This method provide accurate genetic information because it is not influenced by the environment. This study was conducted to analyze the genetic diversity of potato Superjhon, Atlantic, Dessire, Nadia and Granola using RAPD marker. Amongst the 14 random primers, only 7 primers produced polymorphic banding pattern. Sixteen DNA bands of total 28 existed DNA bands (57%) were polymorphic. The average of genetic diversity was 26.8 %. The smallest genetic diversity (15.4%) was between Atlantic and Superjhon, whereas the greatest genetic diversity (57.7%) was between Nadia and Dessire. The analysis results showed that potato clustered grouping was based on their characters and their origins. Keywords: genetic diversity, potatoes, RAPD
