This study aims to evaluate yield and yield components in several peanut lines planted in West Java, Indonesia. The genetic materials tested involved 21 genotypes consisting of 18 potential peanut lines (G100, G133, G142, G144, G199, G205, G209, G21, G234, G237, G33, G37, G41, G53, G54, G76, G84, G99) from a selection of 5 biparental population (GWS79A1/”Zebra”, “Jerapah”/GWS79A1, “Zebra”/GWS79A1, GWS79A1/”Jerapah”, “Zebra”/GWS18A1) and 3 comparative varieties (“Gajah”, “Sima”, and “Zebra”) as controls. Results showed that various genotypes have significant effects on plant height (at 9 and 10 WAP), number of branches (at 4, 10, and 12 WAP), flowering age, and harvest age. Some potential lines showed ideal characters expected of a high quality peanut plant. Based on characters such as harvest age, dry pod weight, and productivity, G100, G41, G21, G205, and G84 can be considered the best potential lines. These lines demonstrated high heritability values including characters classified as high category such as plant height, number of branches, age of flowering, age of harvest, harvest index, wet stover weight, fresh pod weight, number of filled pods, number of empty pods, number of filled pods, and weight of 100 seeds. Additionally, these lines also show high productivity, a character classified in the medium category.

Our study aims to determine the agronomic performances of the red chili pepper genotypes developed by the IPB University as compared to the existing commercial varieties. The study was conducted from June 2019 to April 2020 in the Leuwikopo and Tajur experimental fields, IPB University, Bogor, West Java, Indonesia. Leuwikopo and Tajur location differs in the soil type and environments. The experiments at Leuwikopo were conducted twice, once during the dry season, and once during the rainy season. The experiments were set up in a completely randomized block design with a single factor, i.e. sixteen red chili pepper lines, replicated three times in three different environments. The 11 lines evaluated were F8120005-141-16-35-1-3, F8120005-141-16-35-1-4, F8120005-141-16-35-7-1, F8120005-241-2-9-4- 4, F7120005-120-7-1-7-8-1-2, F6074-7-4-2-1, F4074136-2-3, F474077-1, F474035-2-1, F474035-2, F4136074-1-4; these lines were compared to five commercial chili varieties, “Laris”, “Gada” F1, “Kastilo” F1, “Anies IPB”, “Seloka IPB”. Measurements were conducted on time to harvest, fruit length, fruit diameter, weight per fruit, number of fruits per plant, fruit weight per plant, and productivity. The results showed that the curly and large red chili pepper genotypes had similar agronomic performances to the control curly variety “Laris” and “Kastilo” F1, and and “Anies IPB”, “Seloka IPB”, or “Gada” F1 as control variety for the large chili. Our study demonstrated that all large and curly red chili pepper lines developed in IPB University have excellent potentials to be commercialized into superior varieties.

The development of tropical wheat in Indonesia is currently confined to the availability of wheat’s optimal environments in the highlands. Wheat competes with major highland crops, such as vegetables, which also have high economic values. Despite this, the demand for wheat in Indonesia remains high, whether in the form of wheat flour, wheat meal, or oats. Wheat breeders are actively working to create various crossbreeds so that wheat can adapt and perform effectively in lowland areas. The convergent breeding method is one of the strategies employed to produce genotypes with superior performance. Convergent breeding enhances genetic diversity by incorporating superior traits from all parent plants. The breeding results expedite the emergence of genetic combinations between selected parents. This method involves combining several parent varieties with various traits, with the hope that their offspring will inherit all the characteristics of the crossed parents. Our study with wheat convergent breeding has reached the F6 generation, and in this current study we evaluated the performance of each observed trait in different environments, with the goal of determining the levels of homogeneity and homozygosity. The study utilized a randomized complete block design with three replications, and the crops were planted in various locations. The planting locations selected were those that are >1000 m above sea level (asl), and at a lowland of ± 250 m asl. Wheat performance based on stomatal characteristics showed a reduction in the lowland, which indicates a response to climatic conditions in a particular environment. The higher the environmental temperatures, the smaller the stomatal size, which reduces plant water loss. Noteworthy findings include the tallest plant in CBF-6. CAMN23(265), the highest number of tillers in CBF-6. CAMN233 and CBF-6.CAMN8(4), the largest flag leaf area in CBF-7.CAMN60, and the highest 100-seed weight, as well as overall yield in CBF-7.CAMN119. An analysis of the lowland sensitivity index identified ten moderate genotypes that could potentially adapt well and achieve optimal yields.

Pruatjan (Pimpinella pruatjan Molk.) is Indonesian endangered medicinal plant which grows endemically at mountainousarea. To broaden its planting area, an effort to develop low-altitude tolerant genotype of pruatjan had been conductedsince May 2007. Pruatjan seeds harvested from Gunung Putri experimental station (1,545 m asl) were treated with gammairradiation (0-5 krad) and germinated at Gunung Putri. Young seedlings were transplanted into small polybag (Ø 10 cm), anda month later they were moved into 10-kg medium of pot or polybag. Two months later, some of the young plants were moved to Cibadak experimental station (950 m asl) and Cicurug experimental station (550 m asl). All plants were maintained until flowered and produce seeds. The result shows that seeds from all of irradiation level treatments germinated and grew wellalthough the amount of seedlings decreased by the higher level of irradiation treatment. No phenotypic difference of plantsfrom irradiated seed compared with those from non irradiated ones (0 krad). Plants at Cibadak and Cicurug grew faster thanthose at Gunung Putri, and also flowered faster. On April 2008, seeds from 0, 1, 3 and 5 krad treated plant had germinatedat Cicurug, and those seedlings were the candidate genotypes for low-altitude tolerant of pruatjan.Keywords: induced mutation, low altitude tolerant, pruatjan, variability

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

ABSTRACTThe recent scarcity of fuel has stimulated many efforts to remove dependence on petroleum oil by finding alternative sources of new and renewable energy. Jatropha curcas L. has been chosen as a source of biofuel that has an important role as a petroleum oil substitute, especially for producing biodiesel. Possible efforts for the development of Jatropha in Indonesia include exploration of Jatropha plants from various regions of Indonesia, introducing the plants from abroad and plant breeding. The purpose of this study was to study the genetic parameters of morpho-agronomic traits and selection of potential genotype for genetic improvement of Jatropha curcas. The experiment was conducted at the Biotech Center, BPPT from November 2011 to July 2012. The experiment was performed using a complete randomized block design with sixteen genotypes of J. curcas. Five plants were used for each genotype, with three replications. Results of this study showed that genetic diversity of the genotypes based on morpho-agronomic characters was relatively narrow, with genetic diversity coefficient ranged from 2.73% to 9.02%. The broad-sense heritability was high for all characters, ranged from 32.26% to 85.89%. None of morpho-agronomic characters observed in the 16 genotypes was directly correlated to productivity and seed oil content. Number of fruit and total seed number per bunch were the best characters for selection criteria to obtain high dry seed weight. Based on the bi-plot analysis on seed oil content and dry weight characters among the observed genotypes, LMP and CRP x PDI could be recommended as potential F1 parents to be used in constructing F2 population.Keywords: biplot analysis, broad-sense heritability, genetic diversity coefficient

Pedigree selection is a method of selection used in segregating populations which takes the expertise of breeders in achieving the desired goal. This method is implemented on the early generations with a high degree of segregation and is generally performed on highly heritable traits. The purpose of this research was to study the performance of F3 generation segregants and to estimate the genetic parameters to be used for identification and selection of wheat segregants under optimum environmental condition. The research was carried out at the experiment field of Research Institute for Ornamental Crops, in Cipanas from May to September 2012. Genetic material used were 58 F3 family and six check varieties, namely Dewata, Selayar, Oasis, Rabe, Basribey, and HP 1744. The experiment used an augmented design. Results of analysis of variance showed that the family effect was significant for days to flowering, days to harvest, percentage of empty florets, number of grains per panicle, grain weight per panicle, number of seeds per plant and seed weight per plant. High heritability estimates were found in days to flowering, days to harvest, seed filling period, percentage of empty florets, number of grains per panicle, grain weight per panicle, number of seeds per plant, and seed weight per plant. These characters are suitable for yield improvement of tropical highland wheat due to its high heritability values. The mean value of F3 generation changes subsequent to selection either based on grain weight per plant, or based on number of productive tillers, number of grain per panicle, and grain weight per plant. Keywords: selection criteria, segregation, tropical, yield
