Abstract

The purpose of this study is to suspect additive variants, dominant variants, genetic variants, environmental variants, phenotype variants, narrow-meaning heritability (h2ns), broad-meaning heritability, (h2bs), general joining power, special joining power, heterosis, and heterobioltiosis. The chili elder seeds used are seeds of superior varieties of chili from research in the collection of genetics and plant breeding IPB. The genotype consists of IPB C2, IPB C9, IPB C10, IPB C15 and half-diallel cross seeds. To suspect the reciprocal effect, IPB C10 x IPB C2 crosses were used. The chili seed vigor testing method used was a rapid removal method with 20% methanol at five time periods of 0, 2, 4, 6 and 8 hours. Observations on 7 benchmarks, namely (1) seed germination (DB), (2) radicle length (PR), (3) hypocotyledonous length (PH), (4) normal sprout wet weight (BK), (5) growing speed (KCt), (6) electrical conductivity (DHL) and (7) moisture content (KA). Estimation of genetic parameters using combinability analysis. The results of estimating the reciprocal effect showed that the rate of decline in vigor in germination, growth speed and electrical conductivity, there was no maternal influence so that the genes that control seed vigor were controlled by the nucleus, while the rate of decline in vigor in radicle length and hypocotyl length was influenced by maternal effects. The results of the analysis showed that the rate of decline in chili seed vigor controlled by the core gene resulted in medium to high broad heritability values, and heritability in a very low to medium narrow sense. The elder whose general joining power value is high is IPB C15 elder and the cross whose special joining power value is high and the positive heterosis value is IPB C9 x IPB C10 cross. Keywords: Genetic Parameters, Half Diallel, Vigor Chili Seeds, Hybrids  INTISARITujuan penelitian ini adalah menduga varian aditif, varian dominan, varian genetik, varian lingkungan, varian fenotipe, heritabilitas arti sempit (h2ns), heritabilitas arti luas, (h2bs), daya gabung umum, daya gabung khusus, heterosis, dan heterobioltiosis. Benih tetua cabai yang digunakan adalah benih varietas unggul cabai hasil penelitian koleksi bagian genetika dan pemuliaan tanaman IPB. Genotype tersebut terdiri dari IPB C2, IPB C9, IPB C10, IPB C15 dan benih persilangan half diallel. Untuk menduga efek resiprokal digunakan persilangan IPB C10 x IPB C2. Metode pengujian vigor benih cabai yang digunakan adalah metode pengusangan cepat dengan methanol 20% pada lima periode waktu 0, 2, 4, 6 dan 8 jam.

Abstract

One of the problems of horticultural seeds is the lack of quality of seeds. This experiment aims to evaluate the methods of rapidly pouring hybrid, non-hybrid, local, introduced cayenne pepper seeds and large quantities produced in 2014 and 2016. Non-hybrid seeds were 4 production genotypes in 2014 and 4 in 2016. The hybrid seeds used were 10 production genotypes in 2014 and 8 in 2016. The data analysis used is an analysis of the regression line's angle of inclination, which is the angle resulting from the comparison of the ordinate and abscissa. Based on the results of rapid pouring tests using 20% methanol for 0, 2-, 4-, 6- and 8-hour information, the storability of seeds produced in 2014 was better and higher than in 2016 Therefore, hybrid chili seeds and non-hybrid chili seeds have the same seed storability vigor, as well as between local vs introduced chili seed also large chili seed vs cayenne pepper.

Abstract

This study aims to explore the potential of sorghum development in Indonesia by evaluating the interaction between different sorghum varieties and urea fertilizer dosages. The research employed a Randomized Complete Block Design (RCBD) with two treatment factors: three sorghum varieties (Bioguma 1, Bioguma 2, Bioguma 3) and four urea dosages (0, 50, 100, 150 kg/ha), resulting in 12 treatment combinations replicated three times. Conducted over four months in a sub-urban area of Jakarta, the site was characterized by warm temperatures, high humidity, and unstable weather conditions including rain and strong winds. Despite these challenges, sorghum plants showed consistent growth. The results revealed that the interaction between sorghum varieties and fertilizer dosages significantly influenced plant development. Among all combinations, Bioguma 3 treated with 150 kg/ha urea demonstrated the best performance. These findings emphasize the importance of selecting optimal variety and fertilizer combinations to enhance sorghum cultivation in similar agro-climatic regions.

Abstract

The ability of seed to maintain seed quality during storage is called seed vigor. Accurate method for seed vigor testing of pepper seeds is necessary to accurately determine seed storability during seed distribution. The aim of this research was to determine the best accelerated aging method (AAM) of pepper seed. Freshly harvested seeds of Capsicum annuumL., IPB C9 genotype were used in this study. The experiment used randomized complete block design (RCBD) with three replications. The experimental treatments were seed vigor testing methods i.e. natural deterioration test at room temperature in controlled humidity (RH 90-95%), and four AAM (hot water 60 ºC, methanol 20%, ethanol 20%, and high temperature at 40 ºC). The best method was selected using analysis of variance, coeficient of variance, regresion dan t student analysis. AAM using 20% methanol at periods of 0, 2, 4, 6 and 8 hours was the best method of seed vigor testing for pepper seed. Keywords: accelerated aging, deterioration, ethanol, methanol, high temperature
