Successful application of genetic transformation technique, especially in developing rice variety resistant to brown plant hopper and stem borer, will depend on transgene being expressed and the gene inherited in a stable and predictable manner. This study aimed to analyse transgene segregation pattern of the progenies and the crosses of transgenic rice cv. Rojolele harboring cry1Ab and gna genes. The third generation (T2) of fivetransgenic Rojolele events containing gna and/or cry1Ab were evaluated for two generations to identify the homozygous lines and to study their inheritance. The homozygous lines were selected based on the result of PCR technique. The segregation patterns of gna and cry1Ab were studied in eight F2 populations derived from Rojolele x transgenic Rojolele homozygous for cry1Ab and or gna and their reciprocal crosses. DataÂ resulted from PCR of F2 population were analysed using a Chi Square test.The study obtained six homozygous lines for gna, namely A22- 1-32, A22-1-37, C72-1-9, F11-1-48, K21-1-39, K21-1-48, and two homozygous lines for cry1Ab, namely K21-1-39 and K21- 1-48. Both cry1Ab and gna transgenes had been inherited through selfing and crossing with their wild type as indicated from the F1 containing gna and cry1Ab as many as 48.4% and 47.4%, respectively. In six of the eight crosses, gna was inherited in a 3:1 ratio consistent with Mendelian inheritance of a single dominant locus, while in the remaining two crosses, gna was segregated in a 1:1 ratio. The presence of cry1Ab in F2 populations also showed a 3:1 segregation ratio in all crosses. In the F2 population derived from F1 plant containing cry1Ab and gna, both transgenes segregated in a 9:3:3:1 dihybrid segregation ratio. This study will add to the diversity of geneticsources for insect resistance and allow further use of these transgenic lines for pyramiding resistance to brown plant hopper and stem borer orÂ separately in rice breeding programs whenever the efficacy tests and biosafety requirements have been completed.

The objective of this study were to obtain information about genetic parameters of agronomic characters of sorghum populations derived from Single Seed Descent (SSD) method, and to estimate selection differensial and also to select of F4 population that have a high yield and medium plant height . The experiment was carried out at Leuwikopo Farm, Darmaga, Bogor from January to April 2014. The genetic material were F4 population derived from SSD. The results showed that based on the skewness and kurtosis values, all of the agronomy characters observed in this study were poligenic controlled and influenced by additive gene action. The genetic coefficient of variability values for all parameters varied from intermediate to high in F4 population. Agronomic characters in F4 responded positively to selection because of high broad sense heritability estimates. Correlation analysis showed that plant height, number of leaves, stem diameter, panicle length, panicle weight and 100 seed weight have significant and positive correlation to grain yield/plant. Differential value with selection intensity 10 % based on grain yield/plant will increase grain yield/plant 83.89 % and plant height 8.91 % in the next generation, whereas differensial value based on grain yield/plant and plant height will increase grain yield/plants 68.33 % and plant height 0.26 % in the next generation. It means that selected plant were expected increasing yield 83.89 % or 68.33 % in next generation.Keywords: heritability, cefficient genetic variability, correlation analysis, selection differential

Indonesia as a rich biodiversity country has many superior fruit plant germplasms such as sweet star fruit or carambola (Averrhoa carambola L.). Some varieties of carambola which collected at the Germplasm Garden of Research Center for Biotechnology-LIPI have been used for parent trees of fruit plant production. Therefore, they have to be characterized both phenotypically and genetically. The objective of the study was to analyze the relationship between eight varieties of carambola i.e. Malaysia, Penang, Rawasari, Bangkok, Sembiring, Dewabaru, Demak and Dewimurni at the germplasm garden based on phenotypic and genetic characters. Phenotypic characters were observed directly in the field, whereas genetic characters were observed with RAPD markers using 10 primers. Phylogenetic analysis was done using NT-SYS software showed that there were three clusters of carambola varieties. Meanwhile, Malaysia and Penang varieties have closed relationships (96%) compared with the other varieties. The result of the study would be dedicated to updating and completing the existing fruit plant collection database of Plants Germplasm Garden.

Response of six chili varieties to anthracnose disease caused by Colletotrichum acutatum and C. gloeosporioides. Chili is one of the horticultural commodities with high economic value. Chili production is constrained by anthracnose diseases. Losses due to anthracnose can reduce the fruits quality and yields lose. This study aims to determine the resistance of several chili varieties to anthracnose. Genetic material was used six varieties of chili. Ripe chilies were inoculated with two types of Colletotrichum isolates, i.e. C. acutatum and C. gleosporides. The experiment was arranged in a factorial randomized block design with three replications. The first factor were chili varieties: Laris, SSP, Habanero, Cibinong, Ekasari, and Kopay. The second factor was two types of fungal isolates. Observations were made on the incidence and severity of disease due to anthracnose. The results showed that both fungal isolates were effective in causing anthracnose disease in chilies. Habanero was very susceptible to anthracnose. Laris and Ekasari were moderately resistant to anthracnose diseases. These findings are important to develop new Capsicum cultivars that are more adaptive to anthracnose disease.

Water is a fundamental necessity that must be utilized wisely. This study was conducted in Damarkasian Village, located at the foot of Mount Sindoro and characterized by its hilly terrain. The village has a very limited supply of clean water, forcing residents to rely on a neighboring village for their water needs. Although there is a water distribution system in place, only wealthier residents can afford to build their own networks, while those less fortunate must rely on public facilities along the roadside. To address the uneven water distribution, a well-planned clean water distribution system based on gravity flow is essential. Field data collected includes spring water discharge, water quality, distance, and elevation, as well as population data from official statistics. Water discharge was measured using the volumetric method, and elevation and distance were recorded using the Q-GIS application. Network evaluation, conducted using EPANET 2.0 software, indicated a water discharge rate of 12.2 liters per second. To meet the village's water needs through 2037, a discharge rate of 10.57 liters per second is required. A total of 39 service tanks and appropriately sized PVC pipes are planned without the need for pumps, reducing costs. The total budget is estimated at IDR 1.4 billion, with a tariff of IDR 1,300/m³, cheaper than the PDAM rate.PENERAPAN TEKNOLOGI EPANET DALAM RANCANGAN SISTEM AIR BERSIH DI DESA DAMARKASIANAir adalah kebutuhan mendasar yang harus dimanfaatkan secara bijak. Penelitian ini dilakukan di Desa Damarkasian, yang terletak di kaki Gunung Sindoro dan memiliki kontur perbukitan. Sumber air bersih di desa ini sangat terbatas, sehingga penduduk bergantung pada desa tetangga untuk pasokan air. Meskipun ada distribusi air, hanya masyarakat yang mampu yang dapat membangun jaringan sendiri, sementara warga kurang mampu menggunakan fasilitas umum di pinggir jalan. Untuk mengatasi masalah distribusi air yang belum merata, diperlukan perencanaan sistem distribusi air bersih dengan sistem gravitasi. Data lapangan yang dikumpulkan mencakup debit mata air, kualitas air, jarak, dan elevasi, serta data penduduk dari badan statistik. Debit air diukur dengan metode volumetrik, dan elevasi serta jarak dengan aplikasi Q-GIS. Evaluasi jaringan menggunakan software EPANET 2.0 menunjukkan debit air sebesar 12,2 lt/detik. Untuk memenuhi kebutuhan penduduk hingga 2037, diperlukan debit 10,57 lt/detik. Sebanyak 39 bak pelayanan dan pipa PVC dengan diameter yang sesuai direncanakan tanpa pompa, yang menghemat biaya. Total anggaran sebesar Rp. 1,4 miliar, dengan tarif Rp. 1.300/m3, lebih murah dari PDAM.

Chili pepper is an important agricultural crop but is highly vulnerable to viral diseases, including Pepper yellow leaf curl Indonesia virus (PepYLCIV). This study investigated the biochemical response of chili plants to PepYLCIV infection by examining changes in antioxidant enzyme activities: peroxidase (POD), catalase (CAT), and ascorbate peroxidase (APX). The effects of sample handling methods on enzyme activity measurements were also evaluated. The experiment was conducted in a biosafety greenhouse using a factorial design with four replications. The treatments included two chili varieties (Bara and Bonita), plant condition (healthy and PepYLCIV-infected), sample types (fresh leaf tissue and frozen leaf tissue stored at −80 °C), and seven sampling times (1, 3, 5, 7, 14, 21, and 28 days post-inoculation). Result showed that POD activity was significantly higher in infected plants than in healthy plants, whereas CAT and APX activities showed no significant differences between plant health conditions. Fresh samples consistently exhibited higher enzyme activity than frozen samples. POD and CAT activities peaked at 28 days post-inoculation, while APX activity was the highest at 5 days post-inoculation and fluctuated over time. These findings highlight the importance of considering infection status, sampling time, and sample processing when evaluating antioxidant enzymes in plant–virus interaction studies.
