Understanding genetic variability is crucial for enhancing the breeding programs of butterfly pea (Clitoria ternatea L.), particularly in the face of the demand for improved crop varieties. This study aims to (i) evaluate the genetic variability of 12 butterfly pea accessions based on 28 agro-morphological traits and (ii) analyze the genetic relationships among these accessions. The research was conducted from December 2022 to October 2023 at the Ciparanje Experimental Field, Faculty of Agriculture, Universitas Padjadjaran. The experimental design employed a Randomized Complete Block Design (RCBD) with 12 accessions and three replications. Observations were made on 28 agro-morphological traits. Data analysis was performed using analysis of variance (ANOVA), principal component analysis (PCA), and agglomerative hierarchical clustering (AHC). ANOVA results indicated significant diversity among the 12 accessions based on 17 agro-morphological traits. PCA results showed that the first six principal components accounted for 89.1% of the total genetic variability and identified all traits as contributing factors to the genetic variability among the accessions. AHC analysis grouped the accessions into two main clusters, with Euclidean distances ranging from 1.00 to 4.00, indicating varying levels of genetic relatedness. These findings underscore the importance of genetic variability in formulating breeding strategies, particularly in the selection of parents based on targeted agro-morphological traits. ABSTRAK Informasi keragaman genetik sangat penting untuk mendukung program pemuliaan tanaman telang (Clitoria ternatea L.), khususnya dalam menghadapi permintaan varietas unggul. Penelitian ini bertujuan untuk (i) mengevaluasi keragaman genetik dari 12 aksesi kembang telang berdasarkan 28 karakter agro-morfologi dan (ii) menganalisis hubungan genetik di antara aksesi-aksesi tersebut berdasarkan 28 karakter agro-morfologi. Penelitian dilaksanakan pada Desember 2022 hingga Oktober 2023 di Kebun Percobaan Ciparanje, Fakultas Pertanian, Universitas Padjadjaran. Desain eksperimen menggunakan Rancangan Acak Kelompok Lengkap (RAKL) dengan 12 aksesi dan tiga ulangan. Pengamatan dilakukan pada 28 karakter agro-morfologi. Analisis data dilakukan dengan analisis varians (ANOVA), analisis komponen utama (PCA), dan pengelompokan hierarki aglomeratif (AHC). Hasil analisis ANOVA menunjukkan bahwa 12 aksesi telang beragam secara signifikan berdasarkan 17 karakter agro-morfologi. Hasil PCA menunjukkan bahwa enam komponen utama pertama menjelaskan 89,1% dari total keragaman genetik dan mengidentifikasi 28 karakter agro-morfologi sebagai karakter yang berkontribusi terhadap keragaman genetik 12 aksesi telang. Analisis AHC mengelompokkan 12 aksesi menjadi dua kelompok utama dengan jarak Euclidean berkisar antara 1,00 hingga 4,00, mengindikasikan tingkat kekerabatan genetik yang jauh. Temuan ini menegaskan pentingnya keragaman genetik dalam merumuskan strategi pemuliaan yang efektif, terutama dalam pemilihan tetua berdasarkan karakter agro-morfologi yang ditargetkan.

Cultivating soybean in wetland areas presents unique challenges, particularly during water-limited conditions like dry season, where yield performance can vary significantly among genotypes. This research aimed to assess the yield potential of Indonesian soybean varieties in wetland during dry season, to estimate genetic parameters, and to determine the relationship among traits. Twenty soybean genotypes were evaluated using Randomized Complete Block Design (RCBD) with three replications. Yield components measured included seed weight per plot, number of seeds per plant, and overall yield potential (tons per hectare). The results revealed significant variation among the genotypes. The estimation of genetic parameters indicates that traits comprising plant height, 100-seed weight, and the number of seeds per plant have high heritability and significant CVG/CVP ratios, suggesting efficient genetic selection potential and opportunities for genetic improvement through breeding. Pearson’s correlation network plot shows positive associations between traits, including plant height (PH), weight of biomass (WB), weight of seed per plot (WSP) and yield. 'Deja 1' variety exhibited the highest yield potential at 1.75 tons per hectare, while 'BS 99' variety showed the lowest at 0.18 tons per hectare. These findings underscore the importance of genotype selection in enhancing soybean productivity in water-limited environments. The study offers valuable insights for future breeding programs aimed at improving soybean yields in challenging conditions, such as dry season in wetlands, thereby contributing to sustainable agricultural practices in Indonesia.

Cayenne pepper (Capsicum frutescens L.) is a horticultural plant that has high economic value and contains nutrients that the body needs. Cayenne pepper is one of the leading national horticultural commodities, so it is necessary to increase the production of cayenne pepper appropriately. The obstacle that is often faced in the production of cayenne pepper is the disruption of the production of cayenne pepper caused by the attack of anthracnose disease. Anthracnose disease or fruit rot caused by the fungus Colletotrichum capcisi Sydow can result in yield losses ranging from 20-90%. Trichoderma harzianum Rifai. is a soil saprophytic fungus that naturally can be used as a biological agent, because it has antagonism against pathogens in the form of competition for space and nutrients, mycoparasites and antibiosis. The experimental results in the laboratory showed that the biological agent Trichoderma harzianum Rifai was able to suppress the development of anthracnose disease.

Sweet potato (Ipomoea batatas L.) is a nutritionally rich alternative food source with a high starch content and ranks among the world's most important food crops. As a global food commodity, the development of high-yielding cultivars requires the evaluation of promising genotypes. Among the various types, white-fleshed sweet potato (WFSP) is particularly valued due to its suitability as a raw material for flour production. The increasing industrial demand for sweet potato-based flour highlights the urgency to select high-yielding WFSP genotypes to meet market needs. This study aimed to identify WFSP genotypes with superior yield potential and high harvest index. The experiment was conducted from November 2023 to April 2024 in Rancakalong, Sumedang District, West Java, using eight WFSP genotypes and three check varieties (Rancing, Sukuh, and AC Putih). A randomized complete block design (RCBD) with three replications and 11 treatments was employed. Significant variation was observed among genotypes for traits such as number of tubers per plant, tuber weight per plant, number of marketable tubers, total tuber count, and total tuber weight. Six genotypes—Keriting Maja, MZ 154, Sorong, MBD, PR 119, and MNHR—demonstrated high yield performance, with Keriting Maja showing the highest potential at 35.09 t ha-1, making it a strong candidate for future cultivar development.
