Abstract

Guava has several different accessions. Guava diversity needs to be studied and evaluated in order to determine the next steps in the guava breeding. The objective of this research was to characterize and cluster of some guava germplasm collections. The study was conducted at Aripan and Subang experimental farm, Indonesian Tropical Fruit Research Institute from January 2012 to December 2012. Five fruits of each accession were randomly selected sampled and then characterized using UPOV guidelines. Obtained data were analyzed by NTSYS ver.2.1. The Similarity level of 19 accessions ranged from 70 – 90% or the genetic distance was between 0-20%. Dendogram obtained could be clustered into two different groups, namely group I (ARP9406, ARP9407, ARP8653, ARP8742, ARP10.2, JBT001, JBT002, ARP8740, JBT003 and JBT004), group II (ARP10.7, ARP10.6, ARP10.1, ARP10.12, ARP10.9, ARP10.11, ARP8744, ARP8741 and ARP8743). The result of this research can be used for guava breeding. Species diversity and genetic resources are very important to get new varieties. This study would be highly valuable in the future. Keywords :  Guava  Germplasm, Characterization, Clustering

Abstract

Nine different accessions of water apples were evaluated at Indonesian Tropical Fruit Research Institute(ITFRI), Solok, West Sumatera from January 2013 to December 2014. This present study was aimed to evaluate the variability, heritability, genetic advance and its characters in nine different accessions to provide useful information in the improvement program of water apples. The research used Randomized Complete Block Design (RCBD) with two replications. The ANOVA results exposed significant differences at 5% probability level for all characters. Genotypic variance on fruit weight, fruit length, fruit diameter, leaf length were broad. However, the genotypic variance on total soluble solids, leaf width were narrow. The phenotypic variation for all characters was broad. The heritability estimation was categorized as low, moderate, and high. High heritability estimation was recorded for fruit weight, fruit length, fruit diameter, and leaf diameter. Moderate heritability estimation was noticed for total soluble solids. Leaf width had low heritability estimation. High heritability and high genetic advance were observed on fruit weight.

Abstract

Shallot is an important spice and seasoning in Indonesia. It is consumed almost daily in many dishes. The objective of this experiment was to study the effect of the medium and the variety on the yield of shallots grown in a polybag. The experiments were arranged in a two-factorial randomized complete block design with three replications. The factors were medium (1 soil: 1 paddy husk ash and 1 soil: 1 compost) and variety (Agrihorti 1 and Mentes). Data were statistically analyzed by Analysis of Variance (ANOVA), and the means were compared using Honestly Significant Difference (HSD) at P < 0.05. There was no interaction between medium and variety. Overall, all treatments did not significantly affect yield. Varieties were significant differences on bulb diameter; however, they were not significant differences on bulb height, fresh bulb weight per polybag, and bulb number per polybag. Those media are considered as precise media due to they contain organic materials.
