Abstract

Tolerance cultivar is a best control measure to reduce losses due to virus attack in the field.  Study on growth and yield of new cultivars compared to the commercial ones is an important step in cultivar development whether they will be accepted by farmers or not. The objective of this research was to study growth and yield of new chili pepper hybrids developed for CMV tolerance in comparison to a commercial and similar fruit size one. Twelve new hybrids and one commercial hybrid cultivar Prada, as a control, were evaluated in a completely randomized design with 3 replications. In the greenhouse experiment, H23 and H20 showed better vegetative growth compared to other hybrids and control. Hybrid H17 showed the highest yield followed by H5, H4 and H6.  Keywords.  growth, yield, chili pepper hybrids, CMV tolerance

Abstract

Gamma irradiation to induce mutation in plant has been used intensively since several decades ago.  On maize, 275 Gy gamma irradiation have been known to increase genetic variability indicated by their morphological variation.  Identification on genetic changes by molecular technique is important to answer whether there is mutation happening on DNA level of the plants.   The objective of this research was to identify RAPD marker polymorphism on gamma irradiation mutants compared to their parents.  The initial step of the research was to select random primers could positively amplify the maize DNA.  The result showed that selection on 60 random primers yielded 15 primers that positively amplified the maize DNA.  Amplification on both mutants and their parents by those 15 selected primers indicated that only 5 primers yielding polymorphism between mutants and their parents.  Polymorphisms on mutant G1, G3 and G6 were detected on one locus, meanwhile on mutant G7, G8 and G9 were on two loci.

Abstract

Extending the planting area to a less-fertile soil, such as Ultisols, become inevitable choice to increase the national chili pepper production in Indonesia as this types of soil is the largest part of dry land of Indonesia, about 29.7% or around 51 million ha.  However, efforts to increase its productivity by providing sufficient fertilizers application is most frequently inefficient because in the conventional fertilizer applications, broadcasted fertilizer on the soil bed, are not readily available for the plant as their solubility is limited under the plastic mulch and still in the form of granular until the end of planting season.  Fertigation, therefore, maybe the answer for this problem.  The objective of this study was to determine the best NPK fertigation method on four chili pepper hybrids.  The experiment was conducted in a randomized complete block design with three replication, and the treatments were arranged in a split plot design.  As the main plots were NPK fertigation intensity, i.e. 100%, 75%, 50%, 25% and 0% fertigation with the remnant fertilizers were circularly broadcasted surrounding the plant.  As the subplots were chili pepper hybrids, i.e. ‘Maxima’, H39, H14, and ‘UNIB CHR17’.  The results showed that there was no interaction effect of fertigation intensity indicated that all hybrid genotypes showed similar pattern of responses.  The H39 hybrid had better vegetative growth compared to other hybrids in term of plant height, dichotomous height, stem diameter, number of branches, plant fresh-weight.  Whereas the hybrid cultivar ‘Maxima’ showed the highest yield followed by H14 and cultivar ‘UNIB CHR17’.  The 100% fertigation was the best method of NPK fertilizer application for chili pepper in Ultisols.keywowrd: fertigation, chili pepper, fertilizer application, acidic soil

Abstract

Superior hybrid and CMV tolerant cultivar development requires a pair of high heterobeltiosis parents and both of which are CMV tolerant.  Gene introgression has to be accomplished if the tolerance does not exist in the parents. This research was objected to employ DNA markers and morphological traits on identifying the most resemble BC3 CMV tolerant individuals to their recurrent parents to shortcut the backcrossing cycle. This research used fifteen BC3 populations generated from crosses of hybrid parents PBC1354 and PBC378 with tolerant parents of C1024, C1042 and C1043.  The BC3 populations were previously selected for their CMV tolerance and were characterized by RAPD technique and morphological traits. Selection by means of both RAPD marker and morphological traits identified BC3 individuals 99.9% resemble to their recurrent parent. Genotypes B3A24-20, B3A29-13, B3A29-22, B3B12-13, B3B37-9, B3B12-25, B3C16-5, B3C16-16, B3C34-18 99.9% were similar to PBC378, and  B3D11-8, B3D11-17, B3D38-5, B3E12-17, B3E20-22, B3E31-19  were 99.9% similar to PBC1354.   Those genotypes were both similar to their recurrent parent and tolerance to CMV. The employed strategy shortcut CMV tolerance genes introgression through a backcross breeding.

One of the largest coffee-producing areas in Rejang Lebong Regency is Suku IV Menanti Village, Sindang Dataran District. Coffee bean processing produces a by-product, namely coffee skin, which then has the potential to become waste. To help coffee farmers who lack the knowledge and skills to process coffee skin waste, cascara-making training has been held to improve the economy and environmental quality. This program aimed to empower members of the Bima Saktal and Tunas Jaya farmer groups in Suku Menanti Village IV, through the used of coffee skin waste to produce products with added value. The implementation process of this program includes prepared, implemented, mentored, supervised, evaluated, and program sustainability planned. The results of the implementation of this activity are showing positive results with the motivation of participants who are quite enthusiastic about participating in this program. This community service activity increases community knowledge and skills about the use of coffee skins to become cascara, cascara processing techniques, and techniques for creating quality and safe cascara for consumption. The potential for sustainability of this program is supported by the establishment of coffee shops in the local village and Village IV Suku Menanti as a tourist village so that it is expected to help market cascara products to support the sustainability of the social, economic, and environmental aspects of the local community.

Abstract

A comprehensive assessment of genetic diversity offers invaluable insights to breeders. This study aims to analyze the genetic diversity of 19 cayenne pepper genotypes using morphological and SSR markers.  Morphological markers are essential for evaluating visible traits while SSR markers provide deeper insights into genetic variation. Using both morphological and SSR markers provides a more robust, multidimensional approach to understanding genetic diversity. Morphological characterization was conducted on 19 bird pepper genotypes using 30 distinct traits, further divided into 95 sub-traits, to evaluate vegetative and generative growths. Molecular profiling was carried out using 10 SSR primers. The SSR analysis yielded 80 scorable bands, of which 72 were polymorphic. The high polymorphic information content suggests that these markers were effective in differentiating the genotypes.   The genetic diversity within the population was substantially high, providing valuable genetic material for breeding programs. Genetic similarity analysis divided the population into six distinct groups. Among them, Group I (genotype A05 Taiwan) and Group VI (genotype A02, Bengkulu Indonesia) formed unique, solitary groups, distinguishing them from other clusters. This information is highly beneficial for bird pepper cultivar development, emphasizing the importance of incorporating additional traits to align with the cultivar development of high yielding and saline-stress tolerance.

Abstract

A research was conducted to identify the genetics of upland rice cultivars using random amplified polimorphic DNA (RAPD) markers. Five out of 60 random primers that capable to amplify the most number of markers were OPE-07 (AGATGCAGCC), OPE-15 (ACGCACAACG), OPH-13 (GACGCCACAC), OPH19 (CTGACCAGCC), and OPM-02 (ACAACGCCTC). The number of markers amplified were 5, 6, 8, 8, and 7, respectively. RAPD-PCR using these 5 primers arranged to DNA templates of 41 rice cultivars amplified 1127 RAPD markers. Polymorphic information content (PIC) of each primer were 0.79, 0.80, 0.87, 0.87, and 0.72, respectively. Cluster analysis using a UPGMA dendogram showed that the 41 cultivars were grouped into 9 clusters with genetic similarity index more than 90 percent.
