Abstract

ABSTRACTThe diallel cross analysis method was developed to obtain genetic information involved in a population formed closely to Hardy-Wienberg equilibrium. The objective of this research was to study the genetic parameters on yield component of crossing on big and curly species of red pepper using Hayman approach for dialel cross-analysis method. This approach used 6 parental genotypes and 30 full-diallel cross combinations F1 hybrids. Appearance of the character was controlled by one up to two groups of positive additive genes. Each character observed has a partial dominance. Dominant genes were found much more in the parental characters of weight per plant (IPBC120), flesh thickness of fruit (IPBC2), fruit diameter (IPBC159), and fruit length (IPBC2). The broad sense heritability values on each character was high. Whereas, narrow sense heritability value for some characters were also high, except for character of weight per plant which were moderate.Keywords: additive effects, dominant effects, gene, heritability

Abstract

Urban farming activities are needed to support food security, nutrition, and vitamins for families in urban areas. Information on the characteristics of tomato varieties for urban farming in the greenhouse is still limited. The objective of this research was to evaluate the horticultural characteristics of several hybrid tomato varieties grown in the lowland greenhouse. The experiment was carried out using a randomized complete block design (RCBD) on 5 hybrid tomato varieties with 3 replications at Gunadarma University’s greenhouse, Depok City, West Java, from October 2018 to January 2019. There were significant differences for all quantitative characters among 5 varieties. Tymoti and Tantyna varieties showed good performance at lowland and had good size for vegetable tomato type. Agatha and Ultima varieties showed a fruit size decreasing to 40% in lowland greenhouse. Rewako variety was not suitable for lowland because of the highest flower dropping and lowest fruit setting. Plant growth, young fruit color, and fruit shape in the longitudinal section are important identification keys of tomato variety.

Abstract

Seleksi peubah tanaman cabai secara visual dengan memilih fenotipe yang dianggap baik belum dapat memberikan hasil yang memuaskan tanpa berpedoman pada nilai-nilai parameter genetik, yaitu: nilai heritabilitas, ragam genetik, ragam fenotipe dan koefisien keragaman genetik (KKG). Dalam kegiatan seleksi terhadap daya hasil, menggunakan satu peubah saja kurang efektif dan seleksi akan efektif bila menggunakan beberapa peubah secara simultan menggunakan indeks seleksi. Penelitian ini bertujuan untuk menduga parameter genetik, variabilitas dan heritabilitas beberapa karakter agronomi galur cabai serta untuk mendapatkan galur yang memiliki daya hasil tinggi melalui metode indeks seleksi. Penelitian dilaksanakan di Kebun Percobaan IPB Leuwikopo, berlangsung dari bulan Juli sampai bulan Desember 2010. Percobaan disusun dalam Rancangan Acak Kelompok, faktor tunggal terdiri atas 15 galur cabai dengan 3 ulangan. Analisis data menggunakan uji F, uji lanjut Duncan’s New Multiple Range Test (5%), pendugaan parameter genetik dan indeks seleksi. Hasil penelitian menunjukkan semua peubah yang diamati memiliki nilai koefisien keragaman dengan kriteria yang luas dan memiliki nilai heritabilitas dalam arti luas kriteria tinggi. Galur cabai yang terseleksi adalah IPB009019, IPB002046, IPB002005, IPB002001 dan IPB009002. Terdapat 3 galur hasil persilangan cabai lokal dan introduksi terpilih yang diduga memiliki hubungan kekerabatan jauh serta berpotensi berdaya hasil tinggi.

Abstract

Pertumbuhan tomat pada lingkungan berbeda memberikan perbedaan hasil karena adanya interaksi genetik x lingkungan yang mempengaruhi ekspresi suatu gen pada kondisi lingkungan tertentu. Penelitian ini bertujuan untuk menduga nilai ragam genetik serta nilai heritabilitas arti luas pada genotip tomat tipe determinate di dua lingkungan tanam. Penelitian dilakukan dari Maret hingga Juli 2021 dengan menggunakan Rancangan Kelompok Lengkap Teracak (RKLT) di dua lingkungan tanam (Depok dan Jakarta). Perlakuan terdiri dari 3 genotip tomat generasi F6 dan 2 varietas komersil diulang sebanyak 3 kali. Hasil penelitian menunjukkan bahwa lingkungan tanam memberikan pengaruh terhadap pertumbuhan dan perkembangan genotip tomat yang digunakan. Nilai ragam genetik pada setiap karakter tergolong dalam kriteria sempit, kecuali pada karakter tebal daging buah dan luas daun. Nilai heritabilitas arti luas terhadap karakter yang diamati menunjukkan kriteria tinggi, kecuali pada karakter diameter buah (kriteria sedang) dan karakter tinggi tanaman (kriteria rendah). Genotip RwTa-4-10U-6U-4U-2U memberikan penampilan terbaik pada kedua lokasi tanam, dengan tinggi tanaman lebih rendah (91,09 cm), diameter batang lebih kekar (9,69 mm), buah lebih panjang (5,64 cm), diameter buah lebih besar (4,25 cm), total padatan terlarut lebih tinggi (5,22ºBrix), bobot per buah lebih besar (48,43 g), serta umur berbunga lebih genjah (25 HST) dibandingkan varietas Tantyna dan varietas Tora.ABSTRACTTomatoes growth in different environments give different results due to genetic x environment interaction that affect the expression of genes in a certain environmental condition. This study aimed to estimate the genetic variance and the broad sense heritability of determinate tomato genotypes in two growing environments. The study was conducted from March to July 2021, using a Randomized Complete Block Design (RCBD) in two planting environments (Depok and Jakarta). The treatments consisted of 3 genotypes of tomato generation F6 and 2 commercial varieties with 3 replications. The results showed that the environment affected the growth and development of the tomato genotypes used. The genetic variance was classified into narrow criteria except for flesh thickness and leaves area. The heritability value showed high value except for fruit diameter (medium) and plant height (low). The genotype RwTa-4-10U-6U-4U-2U gave the best performance at both planting locations, with lower plant height (91.09 cm), more harder stem diameter (9.69 mm), longer fruit (5.64 cm), larger fruit diameter (4.25 cm), higher total dissolved solids (5.22ºBrix), greater weight per fruit (48.43 g), and early flowering (25 DAP) compared to the Tantyna and Tora varieties.

Abstract

Organic farming plays a very important role in maintaining environmental balance because it can reduce the use of harmful synthetic chemicals. This LOF is considered capable of enhancing soil fertility and supporting plant growth, while simultaneously reducing waste from the aquaculture sector. This study aims to evaluate the effect of liquid organic fertilizer (LOF) from catfish pond wastewater on the productivity of pakcoy (Brassica rapa L.) plants grown in soil with low nutrient content. The research was conducted in the experimental field of Universitas Gunadarma, East Jakarta, using 18 combinations of POC treatments with various concentrations and five varieties of pakcoy. Data were analyzed using the F-test to determine the overall treatment effect, followed by the Duncan Multiple Range Test (DMRT) at a 5% significance level to compare between treatments. The research results show that the application of POC from catfish pond wastewater has a positive effect on the growth of pakcoy compared to the control. A POC concentration of 0.75 ml/L yielded the best results in most parameters, including plant height, number of leaves, as well as leaf length and width. Although not all treatment combinations yielded significant results, the use of POC generally shows great potential in increasing the productivity of pakcoy plants. POC from catfish pond wastewater is not only effective as an organic fertilizer but also supports sustainable agriculture by reducing the negative impact of aquaculture waste on the environment. This research recommends POC as an environmentally friendly fertilizer alternative to improve agricultural yields, especially in areas with low nutrient content, through gradual soil quality improvement.

Abstract

Rapid population growth has led to greater nutritional needs and increased market demand, but this has also been accompanied by a decline in food production due to land conversion. This study aims to analyze the impact of crop variety on the growth and yield of lettuce, as well as the impact of AB mix concentration on the growth and yield of lettuce in a Nutrient Film Technique (NFT) hydroponic system. This study employs a nested design with two variables: variety and AB mix concentration. The variables studied in this research include AB mix concentration and lettuce crop variety, each with three replications. The AB mix concentrations applied were 800 ppm, 1,000 ppm, 1,200 ppm, and 1,400 ppm. The lettuce varieties used were General, Georgia, and Kanita 19. The results showed significant differences in all parameters between lettuce varieties, except for the weight of the heads. The Georgia variety showed the best suitability at a concentration of 1,000 ppm, while the General variety was suitable at a concentration of 1,200 ppm. The Georgia variety recorded the highest results in terms of leaf count and production compared to the General and Kanita 19 varieties.
