Abstract

ABSTRACT: Indonesia is one of the largest producers of sago in the world which is rich in genetic diversity. Improving superior sago varieties can be done through the plant breeding process to determine their genetic characteristics. Genetic diversity can be determined in several ways, namely morphological markers, molecular markers and cytological markers. Molecular markers can be done using several markers, namely nuclear markers (cell nucleus) and cytoplasmic markers. Chloroplast genome markers consist of rbcL and Mat-K. The gene most widely used in research on plant DNA barcoding throughout the world is the Mat-K gene. Analysis of sequencing results for this gene can use the MEGA program to produce kinship relationships. The method used in this experiment is a descriptive method. Based on the research results, it can be concluded that the resulting nucleotide sequence is 578 bp and has 192 amino acids. The genetic distance between the 5 sago cultivars and other palmae species ranged from 0.000-0.003. The phylogenetic tree shows that there are 2 groups with a boostrap value of 75, where in group 1 there is the species Metroxylon sago isolate Sago 15 which has a close relationship with Metroxylon warburgii when compared to other palmae species

Abstract

ABSTRACT : This research aims to identify the diversity of morphological characteristics of several sweet potato accessions cultivated by communities in the two tribes in the Kaimana Regency. The research was carried out in the Lower Arguni District in 5 villages (Coa, Afu Afu, Wetuf/Sawi, Kufuryai, Wermenu) inhabited by the Irarutu and Dani tribes (a local tribe from Wamena). The research used descriptive methods with survey, observation, and interview techniques. The research location was determined deliberately (purposive sampling) based on the local tribe population. The sweet potato in each village was also determined deliberately (purposive sampling) based on the number of accessions and different morphological characteristics. Observation of morphological characteristics included the morphology of stems or tendrils, leaves, and tubers. Data analysis was carried out using cluster analysis with pro- gram NTSYS-pc version 2.0. The morphological character similarity coefficient used is the simple matching coefficient. The research results showed that there was morphological diversity in 26 sweet potato accessions cultivated in five villages by the Irarutu and Dani tribes from Wamena. Diversity in morphological characteristics occurs in the characteristics of tendrils/stems, leaves, and tubers. Based on the results of the grouping analysis, the coefficient of similarity in morphological characteristics of the 26 sweet potato accessions was between 0.41 and 1, which means that the similarity in morphological characteristics was between 41% and 100%. The 26 sweet potato accessions were not grouped based on the village where they were grown but were grouped randomly. At the lowest similarity in morphological characteristics, namely 41%, 26 accessions were grouped into two groups, namely: group I consisted of 17 accessions, while group II consisted of 9 accessions. At the highest similarity, namely 100%, there are several accessions that group together, namely AfuAfu-6 and Wetuf-2; Coa-4, Afu Afu-7, Kufuryai-5; and Afu Afu-10, Wetuf-4, Kufuryai-1.

Abstract

ABSTRACT: This study aims to determine the growth and yield of several genotypes of Unipa red corn. The research was conducted in the Sentani District, Jayapura Regency, from October 2021 to February 2022. The experiment was laid out in a Randomized Block Design (RBD) with a single treatment factor, consisting of 9 Unipa red corn genotypes, 1 local Jayapura genotype, and 1 national genotype. The observed variables included plant height, stem diameter, number of stem segments, length of stem segments, harvest age, cob length without husks, cob weight without husks, cob diameter without husks, weight of 100 seeds, seed weight per plot, seed weight per hectare, and seeds/cobs color. The results showed that: 1) The growth components of 11 corn genotypes vary greatly, and genotype treatment significantly affects the characteristics of plant height 7 MST, stem diameter 7 MST, and stem internode length; 2) The Unipa AMP-6 genotype had the highest productivity of 6.57 tons/ha; 3) The average harvest age of Unipa AMP corn was 87-88 days after planting; and 4) The genotype with the largest percentage of homogeneous seed color was AMP Unipa-8 (90.44%).

Abstract

The purpose of this study was to explore and describe the morphological diversity of sweet potato accessions in Nabire and West Nabire Districts, Nabire Regency. The study was conducted in several villages in Nabire and West Nabire Districts, with altitudes ranging from 3 to 10 m above sea level. The study lasted for 2 months, from December 2024 to January 2025. The study was conducted using a descriptive method with direct observation techniques in the field. The determination of the research location was intentional (purposive sampling), by selecting areas where farmers cultivate sweet potatoes. Observations of plant morphological characters were carried out by the description guide by Huaman (1997). Observations on sweet potato accessions included morphological characters of stems or tendrils, leaves, and tubers. The results of the observations were analyzed, tabulated, and presented in tables and figures. The results of exploration in Nabire District (Sanoba, Kalimangga, Kalibobo, Wonorejo Village) and West Nabire District (Bumiraya, BR-Menou, Kalimerah, Gerbangsadu Village) obtained 70 sweet potato accessions. The number of sweet potato accessions cultivated in Nabire District is more (37 accessions) compared to West Nabire District (33 accessions). From the results of the study, a description of the morphology of the stems, leaves, and tubers of sweet potato plants in Nabire and West Nabire Districts was obtained with a fairly high level of diversity, such as: Stem (tendrils) character from non-twisting to twining, upright type to very creeping type, dominant tendril color from green to dark purple, and from hairless to thickly hairy. Leaf characteristics range from heart-shaped to almost separate, serrated leaf curve type to deep (finger-like), the number of leaf curves varies from 1,3,5,7,9, and the color of the leaves ranges from greenish yellow to purple on both the upper and lower leaves. The tuber characteristics range from round to irregular/curved length, and the dominant color of the tuber skin ranges from white to dark purple.

Abstract

Corn (Zea mays L.) is a strategic food commodity that supports food diversification, particularly in eastern Indonesia. The development of red corn is significant due to its potential as a functional food. However, local corn productivity is generally low, requiring improvement through breeding. This study aims to compare the vegetative characteristics of several genotypes of the AMP-UNIPA promising line cultivated in Webi Village, Rasiei District, Teluk Wondama Regency. The study was designed using a Randomized Block Design (RBD) with 13 corn genotypes, consisting of AMP-UNIPA 1–9 and 4 comparison genotypes (Local Red Anggi, Waxy-corn, Local Wondama, and National Variety). The parameters observed included plant height, number of leaves, leaf length, leaf width, leaf color, stem diameter, length of the 3rd stem node, length of the 4th stem node, number of stem nodes, and stem color. Data were analyzed using ANOVA and HSD at a 95% confidence level. The results showed significant to highly significant differences between genotypes in most vegetative traits, particularly plant height, leaf development, stem diameter, and the length of certain stem segments. Local Red Anggi showed the strongest vegetative performance, particularly in plant height and leaf length, while AMP-UNIPA 5 tended to excel in leaf number and AMP-UNIPA 3 in stem diameter. These results indicate clear vegetative diversity, suggesting that several AMP-UNIPA lines have adaptive potential and are worthy of consideration for further selection.
