Abstract

ABSTRACTHybrid rice varieties  is an alternative technology to improve  productivity of low land rice. The results of previous studies have identified and found the male sterile lines Wild Abortive type and Kalinga are resistant to bacterial leaf blight pathotype III, IV and VIII. The objectives of the research were to obtain information on agronomic characters, yield evaluation, genetic parameters, and repeatability information. The experiment was conducted in two locations namely  Muara and Indramayu experimental stations. The design used was a Randomized Complete Block Design with three replication at each site.  Each replicate consisted of 17 hybrid rice and three check varieties. The results from locations showed that genotype BI485A/BP1 (IR53942) has the highest yield of 5.8 ton ha-1. The coefficient of genetic and phenotypic diversity of six agronomic characters was low. The repeatability for seven character observed were low, except for days to flowering. The  scoring value  of bacterial leaf blight disease in Indramayu showed that nine genotypes exhibit resistance.Keywords: cytoplasmic male sterile lines, disease resistance

Abstract

ABSTRACTThe breeding of rainfed rice tolerant to drought can be accomplished using anther culture. The objectives of this research were to determine regeneration abilities of six F1 anther culture and its acclimatization ability. The experiment was arranged in completely randomized design with 14 replications. The treatments consisted of six F1 derived from crossing:  INPARI 18 x IR83140-B-11-B (G1), INPARI 18 x B12825E-TB-1-25 (G2), INPARI 18 x IR87705-14-11-B-SKI-12 (G3), INPARI 22 x IR83140-B-11-B (G4), Bio-R81 x O18b-1 (G5), Bio-R82-2 x O18b-1 (G6). Media for callus induction was based on N6 medium + 2.0 mg L-1 NAA + 0.5 mg L-1 kinetin + 1.0 mM putresin + 60 g L-1 sucrosa, media for regeneration was based on MS + 0.5 mg L-1 NAA + 2.0 mg L-1 kinetin + 1.0 mM  putresin, and media for rooting was based on  MS + 0.5 mg L-1 IBA + 30 g L-1 sucrosa. The result indicated that all six F1 had different ability in anther culture. Bio-R82-2 x O18-b1 (G6) and  Bio-R81 x O18-b1 (G5) F1 genotype had good response both of callus induction and plant regeneration. These two F1 genotypes also gave the highest ratio of green planlet production to number of anther inoculated (GP:AI) were 5.50% and 4.65%,  respectively. In this research, there were identified doubled haploid plants were developed from 4 F1 derived cross namely G2 (2 plants), G3 (4 plants),  G5 (21 plants), and G6 (26 plants).Keywords: Callus induction, doubled haploid, rice

Abstract

ABSTRACTIncreased of plant productivity in field determined by the use of quality seed from improved variety. The purpose of this research was to study the effect of frequency and volume of phyllosphere biological agents by foliar spray on rice plant infected by Xanthomonas oryzae pv. oryzae (Xoo) in improving plant growth, production of rice seed, and controlling bacterial leaf blight (BLB). This research was conducted at Seed Health Laboratory, Department of Agronomy and Horticulture, Bogor Agricultural University, and Muara Experimental Field, Rice Research Institute, March through September 2014. The experiment was conducted using a randomized complete block design with two factors, and replicates as blocks. The first factor was five levels of frequency of spraying with biological agents: P0 = control, P1 = Xoo seed inoculated then invigorated with biomatriconditioning, P2 = Xoo inoculated seed, then biomatriconditioned, and the plants were sprayed with phyllosphere biological agents F112 once, P3 = as P2, and the plants were sprayed with F112 twice, and P4 = as P2, and the plants were sprayed with F112 three times. The second factor was three levels of spray volume: i.e., 300, 400, and 500 L ha-1. Result of this experiment revealed that biomatriconditioning with rhizobacteria P. diminuta A6 and B. subtilis 5/B improved field emergence and seedling dry weight. Seeds applied with biomatriconditioning then followed by foliar spray with phyllosphere bacteria F112 at 40, 60, and 80 days after transplanting effectively reduced severity of BLB, increased plant dry weight and seed yield. All treatments increased yield as compared to untreated control. Volume of foliar application showed no significant difference, therefore, the lowest volume of 300 L ha-1 was recommended.

Abstract

ABSTRACTBarnyard grass (Echinochloa crus-galli (L.) P. Beauv.) is a major weed competitor to rice production in Indonesia. In order to develop integrated weed management program, a research to select competitive rice lines to E. crus-galli was conducted in a green house of Indonesian Centre of Agricultural Biotechnology and Genetic Resource Research and Development Bogor. The research design was split plot with four replications, E. crus-galli was designed as the main plot (rice without E. crus-galli compared  rice with four E. crus-galli per pot), and the sub-plots were 25 genotypes (23 lines, 1 tolerant variety and 1 sensitive variety). Level of tolerance was determined by the reduction percentage of grains weight, the number of productive tillers and dry matter weight. The results showed that rice competition with E. crus-galli reduced plant height, productive tiller numbers, filled spikelet numbers per panicle, dry matter weight and dry grain weight. Three lines, i.e., IR10L-155, IR10L-133 and BIO-R84-1 were classified as tolerant, 19 lines were moderate and 3 lines were sensitive to E. crus-galli competition.Keywords: Barnyard grass, competition, sensitive line, yield reduction

Abstract

ABSTRACTDrought has become a main barrier of rainfed rice in dry climate and short wet season areas. Growing drought-tolerance varieties is a practical approach to minimize yield lost of rice by the drought stress condition. The aims of this research were to examine the inheritance of drought tolerance character, to identify selection traits, and to estimate genetic gain for drought tolerant on lowland rice. Four rice varieties, i.e., Jatiluhur, Mentik Wangi, IR64, Way Apo Buru, were fully diallel crossed. The parent varieties and the F1’s were grown at Sawah Baru, Dramaga experimental field in two irrigation treatments, optimum and sub optimum where irrigation was applied until three weeks after transplanting. A randomized complete block design with three replications for each irrigation treatment was applied to the experiment. The results showed that there is a significant maternal effect on tiller number. The values of additive variance were higher than the dominance for all other characters except tiller number and grain weight per plant. The highest value for narrow sense heritability was achieved by panicle length.Keywords: diallel, drought, genetic, rice

Abstract

ABSTRACTWeeds has become a big problem in system of rice intensification (SRI), integrated crop management (ICM) and conventional cultivation systems. The objective of the research was to study the dominancy and potential of harmful effect of weed in these three cultivation systems. The research was conducted at Sukamandi research station of Indonesian Center for Rice Research, Subang, from November 2013 to April 2014 during rainy season. The experiment was arranged in a split plot design with four replications. The cultivation systems was main plot consisted of system of rice intensification (SRI), integrated crop management (ICM) and conventional system. The weeding techniques as subplot consisted of no weeding, manual weeding, mechanical weeding and chemical weeding. The result showed that based on dry mass of weeds the highest risk of weed was exhibited at SRI with total dry mass of weed 51.53 g m-2 (0.5 ton ha-1) and the lowest was at conventional system with 32.45 g m-2 (0.3 ton ha-1). Proper weed control increased rice production by 28.9% for SRI, by 29.4% for ICM and by 14.6% for conventional cultivation systems.

Abstract

ABSTRACTIndonesia is one of the largest wheat importers. Suitable environmental condition for wheat needs to be studied if wheat is going to be widely cultivated in Indonesia. The adaptability of wheat grown in various climates and altitudes is one of the important aspects. The objective of this experiment was to study the quantitative and morphological character of wheat grown in middle land (540 m asl) in Bogor, West Java. The experiment was arranged in randomized complete block design with three replications. Wheat genotypes used were three national varieties (Nias, Selayar, and Dewata), four new improved varieties (Guri 3 Agritan, Guri 4 Agritan, Guri 5 Agritan, and Guri 6 Unand), and one introduced genotype (SBD). Data were collected for several quantitative variables and seventeen morphological characters based on UPOV descriptor. The result showed that wheat growth was restricted in Bogor. Genotype determined plant height, leaf number, ear length, root length, number of spikelet, harvest time, seed weight, number of tillers, and plant biomass. Based on ear length, grain weight, and plant biomass, Guri 3 Agritan had the highest production than the other genotypes.Keywords: diversity, genetic relationship, high temperature, introduced genotype, phylogenetic

Abstract

ABSTRACTThe use of probiotic bacteria as biocontrol agents is one of the methods of controlling anthracnose disease caused by Colletotrichum acutatum. The objective of this research was to suppress the infection of C. acutatum and increase chilli pepper seedling vigour. The research involved factorial experiments arranged in a completely randomized design with two factors. The first factor was seed coating involving six treatments, i.e., control, seed coating without bacteria, seed coating with Bacillus sp., Pseudomonas sp., Actinomycetes sp, and fungicide. The second factor was the seed storage period where six storage periods were experimented, i.e., 0, 1, 2, 3, 4, 5, and 6 months. The results showed that the coating treatment of Bacillus sp., Pseudomonas sp., and Actinomycetes sp. improved germination, growth rate and number of leaves and reduced the incidence of attacks and infection of hypocotyls at 5 month storage period.Keywords: Actinomycetes sp., Bacillus sp., Pseudomonas sp., seed coating, storage period

Abstract

ABSTRACTFusaric acid produced by Fusarium spp. played a major role in potato dry rot development. Using fusaric acid as a selection agent may be useful to identify resistant clones. The aim of this experiment was to evaluate the morphological responses of 10 potato clones (Granola, Atlantic, Cipanas, DTO 28, DTO 33, Russet Burbank, IPB 1, CIP 801040, CIP 801045, dan CIP 801050) and their resistance level to fusaric acid and Fusarium solani. The research was conducted in Plant Breeding Laboratory and Tissue Culture Laboratory 3, Departement of Agronomy and Horticulture from April 2014-February 2015. The in vitro experiment was arranged in a randomized block design with 4 fusaric acid concentrations and 4 replications, while the F. solani infection experiment was arranged in a completely randomized design with 5 replications. The result showed that fusaric acid inhibits growth, reduce microtubers production, and caused planlets death. Correlation analysis between in vitro resistance to fusaric acid and F. solani infection on tuber showed positive and notable result. Accordingly, fusaric acid can be used to identify any clones resistant to F. solani.Keywords: Fusarium solani, phytotoxin, selection
