Analysis of genetic diversity using molecular markers is also useful for detecting duplication found among collected clones. The research aimed to determine the genetic diversity of local cacao clones derived from Southeast Sulawesi based on SSR markers and morphological characters. The research was conducted at Cacao Research Sub-Station, Lebojaya Village, Konda Subdistrict, South Konawe Regency, Southeast Sulawesi, and Integrated Laboratory of Indonesian Industrial and Beverage Crops Research Institute Sukabumi, and Molecular Biology Laboratory of Indonesian Center for Agricultural Biotechnology and Genetic Resources Research and Development Bogor, from April to November 2015. Genetic diversity analysis was performed on 21 cacao clones covering 19 local clones and 2 national varieties using 22 SSR markers. The molecular characterization results showed that 11 markers are polymorphic, and subsequently used to group cacao clones using NTSYS program. The grouping results divided the cacao clones into 4 main groups at 0.46 genetic similarity values. Based on genetic distance values >0.7, 8 combinations of cacao clones can be selected as parental clones with the expectation to increase the effect of heterosis on progeny. On the other hand, result of morphological characterization generally indicated the diversity between the four cacao groups. Based on molecular and morphological characterization, it can be seen that cacao clones derived from Southeast Sulawesi have a high diversity and can be utilized in the development program of new improved varieties.","PeriodicalId":201337,"journal":{"name":"Jurnal Tanaman Industri dan Penyegar","volume":"79 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115438728","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The research was conducted in Integrated Laboratory, Seameo Biotrop, Bogor, from July to September 2013. Genomic DNA was isolated from 21 tea genotypes leaf samples, then amplified with primer OPA 03, OPA 05, OPB 04, OPB 06, OPC 06, and OPD 08. Electrophoresis result was converted into binary data. The genetic similarity and cluster analysis calculation was done using NTSYS-pc version 2.10. In this research, 50 polymorphic bands (94,34%) and 3 monomorphic band (5,66%) were obtained. Cluster analysis based on Nei's genetic distance using the unweighted pair-group method with arithmatic (UPGMA) divided 21 tea genotypes into two groups at a genetic similarity value of 0,48. Group 1 consisted of 20 tea genotypes, while the second group comprised only a one genotype (Sin 27). The range of genetic similarity matrix was between 28%–92%, the lowest genetic similarity (28%) was found between GMB 4 and Sin 27 genotypes, while the highest (92%) was found between AS 2 and AS 1 genotypes.

Complex roasting is one excellent method in increasing the added value of coffee, such as Coffea arabica var. Sigarar Utang which is the best coffee variety in Indonesia. The study was carried out at The Indonesian Industrial and Beverage Crops Research Institute (IIBCRI), Sukabumi, West Java, from January to November 2020 which aimed: (1) to evaluate the effect of initial temperature and roasting degree on the quality of Sigarar Utang coffee bean, and (2) to evaluate the mass balance and economic feasibility of the best roasting treatment. This study was designed in a factorial completely randomized design, using 2 factors, and 2 replications. The first factor was the initial temperature which consisted of 2 levels (185 oC dan 210 oC), and the second factor was the roasting degree which consisted of 2 levels (light-medium and medium-dark). The variables observed were the water content, ash content, bulk density, brix, titratable acidity, pH, radical scavenging (antioxidant) activity, and caffeine content. The results showed that the complex roasting method with an initial temperature of 210 oC and mild-moderate roasting degrees generated a quality of Sigarar Utang coffee originating from Gunung Putri, IIBCRI, closest to the quality I of SNI 01-3542-2004. The roasted coffee beans have a special taste (score 86.51) which is a high added value. The production economic value is feasible to be adopted by small-medium scale coffee industry.","PeriodicalId":201337,"journal":{"name":"Jurnal Tanaman Industri dan Penyegar","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121968114","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
