Abstract

Rainfed rice breeding for high yield is an alternative to increase national rice production. The breeding can beaccelerated using anther culture technique. The selection of high productivity lines may be more effective if it also involvesthe traits contributing to or affecting the yield traits. This study aimed at determining suitable characters as selection criteriaand obtain a selection index model for high yielding doubled haploid rainfed rice lines. The experiment was conductedin a greenhouse of ICABOGRAD, Bogor and Sawah Baru Experimental Station, Bogor Agricultural University using arandomized complete block design (RCBD) with three replications. Thirty doubled haploid lines derived from anther cultureand two check varieties namely Ciherang and Inpari 18 were used. The results showed that plant height (TT), number of filledgrain per panicle (GI), and productivity (PRD) could be used as suitable selection characters. The determination of selectionindex obtained a selection model which was Selection index = 0.48 PRD + 0.31 JGI - 0.31 TT. This model can be used toselect high yielding doubled haploid rainfed rice lines.

Abstract

Global warming becomes a pressure in food production sustainability because it affected crop growth and development. The purpose of this study was to obtain information on the effect of high-temperature stress on the growth and development phase of rice and to evaluate the genotype for tolerance to high-temperature stress. Two environment conditions were used in the field and greenhouse of IPB Cikabayan experimental field, IPB University from August 2016 until February 2017. The study used varieties of IPB 4S, IPB 6R, Mekongga, and Situ Patenggang. High-temperature treatment was done by transferring the rice plants to the greenhouse at 50 days after transplanting. Observations were made on the generative phase in two different environmental conditions. The results showed that the total tillers number, filled grain number per panicle, unfilled grain number per panicle, total grain number per panicle, grain filling rate, percentage of filled grain and filled grain weight per plant had different responses among rice genotypes due to high-temperature stress. High-temperature decreased pollen fertility in all genotypes, which classified IPB 4S as a sensitive genotype and Mekongga as a tolerant genotype. This information could be useful for development and improving rice variety to anticipate high-temperature stress. Keywords: Climate change, fertility, pollen, stress tolerance index

Abstract

Morphological characters are basic characters to identify rice cultivars. The information of glutinous rice cultivars in Ponorogo is still very limited, therefore the exploration and characterization of the local cultivar are needed. The research aimed to explore and identify local cultivars based on morphological characters of plant, grain, and milled rice. The research was conducted on March-October 2018 at elevens subdistricts in Ponorogo. There were eleven cultivars have been collected and characterized, namely five white glutinous rice cultivars (Latisa, Tawon, Semok, Pelem, Genjah), three red glutinous rice cultivars (Garingan, Merah Pendek, Jowo), and three black glutinous rice cultivars (Wilis, Gundik, dan Gontor Bulu). The eleven cultivars were varied on plant height, panicle length, flowering time, number of tillers, grain size and shape, and the color of aleurone. The analysis of diversity and similarity on characters showed that all cultivars could be classified into four different groups. The first group was Latisa (Gontor Bulu), the second was Tawon group (Pelem), third was Genjah group (Garingan, Merah Pendek and Jowo), and the fourth was Wilis group (Gundik).

Abstract

Increasing corm production of iles-iles (Amorphophallus muelleri Blume) through genetic improvement is important for increasing farmers? income. However, the study on variety development is rarely reported. Here, yield evaluation of the second growing period was conducted at IPB Experimental Station Leuwikopo Farm, Bogor, Indonesia (-6.5647419, 106.7220331, 17.25z) from August 2017 to July 2018 in order to select candidate clone with high corm production. One-year-old corms of 21 F1 accessions were planted under 55% shading net with four replications. The parent population was set as a control. Results showed that accessions exhibited variation in corm size. The parent population produced corm ranged 622.3-908.3 g in weight (on average 764.2 g). The pooled accessions produced corm 180.7-1527.5 g in weight, corm diameter 71.0-145.8 mm, and corm height 46.6-87.6 mm. Nine accessions produced 5.91-99.88% higher average corms weight than the parent, i.e., BKB, BS, CF, CK, CR, DPG, DPP, SBM, and SHJ. Based on 30% as the basis of corm weight improvement, we concluded that five accessions, i.e., CK, CR, DPG, DPP, and SBM as prospective candidate clones. These accessions could be further evaluated in the third growing period to select best candidates of new variety of A. muelleri.Keywords: Agamosporous, Araceae, breeding strategy, new variety, productivity

Abstract

Maize is an important crop in Indonesia that is utilized for food, feed, and industry. Waterlogging is one of the abioticstresses challenging maize production in recent years due to climate changes. Vegetative-phase screening methods may benefitplant breeding programs because potential genotypes can be identified at earlier stage with lower cost. This study consistedof two experiments. The first experiment was carried out at the Sawah Baru experimental station of Bogor AgriculturalUniversity (IPB), Bogor, from June to September 2017 using an alpha lattice design with three replications and four blockswithin each replication. The second experiment conducted in a greenhouse at Cikabayan experimental station of IPB, Bogor,from December 2017 to January 2018 using a randomized complete block design with three replications. Genetic materialused were 21 maize genotypes from the Indonesia Cereal Research Institute (ICERI) and IPB, including 19 hybrids and 2inbred lines. The results showed that the dry root weight under normal conditions had significant positive correlation withgrain yield under waterlogging stress, and therefore is potential for early screening. Adaptive genotypes in waterloggingstress selected based on dry root weight are DKLx30, DKLx11, MGoldx37, MGOldx41, and IPB L15-1xMR14. Predictedmean yield across these genotypes was 0.57 ton ha-1 higher yield than the overall mean in waterlogging stress condition.Selected hybrids can be further evaluated for variety release.

Abstract

Global climate change will imply to increase in atmospheric temperature, which can affect the sensitive stadia and decrease rice yield. The objective of this research was to study the growth and production of rice varieties under hightemperature stress. This research was conducted using a split-plot design under partitioned polyethylene house in order to create temperature differences among main-plots. The partitioned treatment successfully increased by 1.7 °C of average temperature with a maximum temperature of 35.0 °C (T1) and 37.6 °C (T2). Rice varieties, namely IR64, Ciherang, IPB-3S, Way Apo Buru, Jatiluhur, Menthik Wangi and Silugonggo were randomized as sub-plot. The results showed that increasing temperature had no significant effect on plant height, tiller number, SPAD-value, leaf area index, and crop growth rate, but significantly decreased 1,000 grains weight by 4.57% and harvest index by 20%. The interaction between temperature and varieties significantly affected a percentage of a productive tiller and partially filled spikelets. Ciherang variety produced the lowest percentage of productive tillers on T2 by 57.6%. Way Apo Buru variety produced the lowest percentage of partially filled spikelets on T2 by 3.01%.

Abstract

Siam weed growing in any locations can be used for developing organic agriculture in Indonesia. The research was to find the quantitative and qualitative potential of siam weed as compost material for organic shallot cultivation. This study was descriptive-quantitative research using survey method done in four regencies in Yogyakarta Special Province and laboratory analysis. Purposive random sampling was used in survey method to determine the samples by applying random sampling and nested design. Laboratory analysis was to know nutrient content of siam weed. Shallot was planted using siam weed compost of 10 and 20 ton ha-1, inorganic fertilizer of 500 kg NPK Mutiara 16-16-16 ha-1 and the control. Siam weed was potential for developing organic shallot in Indonesia. Siam weed produced fresh biomass of 80 ton ha-1 with the population density of 24-37 individual m-2 and spread over almost all locations in Yogyakarta Special Province. Siam weed also contained higher nutrients of 2.56% N, 0.38% P, and 2.41% K with C/N ratio of 19.52 under the critical point of 30 so that easy to mineralized.
