Abstract

ABSTRACTCombination of Somaclonal Variation and Mutagenesisfor Crop Improvement. Endang G. Lestari. Mutation-basedplant improvement, which changes one or a few specifictraits of a cultivar, can contribute to crop improvement.Tissue culture increases the efficiency of mutagenictreatment to induce variations. In vitro culture incombination with induced mutation can speed up thebreeding program by generating variability, followed byselection and multiplication of the desired genotypes. Inmany vegetative propagated crops, mutation induction incombination with in vitro culture techniques can be themost effective method for plant improvement. In seedpropagated species, the application of mutation coupledwith doubled haploid systems seems to be highly promisingin crop improvement. This approach speeds up the breedingprogram through generation of variability followed byselection of homozygousity and rapid multiplication ofdesired genotypes.

Abstract

ABSTRACTIndirect Organogenesis and Somatic Embryogenesis ofPineapple Induced by Dichlorophenoxy Acetic Acid. IkaRoostika, Ika Mariska, Nurul Khumaida, and Gustaaf A.Wattimena. This research aimed to study the effect of 2,4-D,AdS, and basal media to the regeneration of pineapplethrough indirect organogenesis and somatic embryogenesis,and to study the complete event of somatic embryogenesis.Callus formation was induced by 21, 41, and 62 μM 2,4-Dwith addition of 9 μM TDZ. The non embryogenic calli weretransferred onto 4.65 μM Kn containing medium.Embryogenic callus formation was induced on MS or Bacbasal media consisted of N-organic compounds withaddition of AdS (0, 0.05 and 0.1 μM). The embryogenic calliwere regenerated on modified MS medium with addition of0.9 μM IBA, 1.1 μM BA, 0.09 μM GA3 or MS mediumsupplemented with 0.018 mM BA. The result proved that thesingle auxin of 2,4-D was not enough to induce embryogeniccells. Therefore the non embryogenic calli were regeneratedthrough organogenesis. The 21 μM 2,4-D yielded high level ofcallus formation (80%), higher fresh weight (0.2 g/explant)and higher number of shoot (25 shoots/explant in twomonths). Embryogenic calli were produced on N-organiccompounds enriched media. The regeneration mediumsignificantly affected the level of browning, where the MSmedium with addition of 0.018 mM BA yielded lower level ofbrowning. There was an interaction of embryogenic callusinduction medium and regeneration medium to the numberof mature somatic embryos. The embryogenic callusinduction on MS medium enriched with N-organiccompounds and 0.05 μM AdS followed by the regenerationof somatic embryos on MS medium with addition of 0.018mM BA was the best treatment which yielded 17 maturesomatic embryos/explant

Abstract

ABSTRACTIn Vitro Culture of Entomopathogenic Nematodes(Rhabditida: Steinernema and Heterorhabditis) in StaticLiquid Media. Chaerani, M. Ace Suhendar, and J.Harjosudarmo. Entomopathogenic nematodes belongingto genera Steinernema and Heterorhabditis are potentiallymost effective and safe biological control agents for insectpests, especially for soil dwelling insects and those living incryptic habitats. Field application of the nematodes is stillhampered by supply of large number of infective juvenile(IJ) nematodes. Five published in vitro media along with itstwo modifications were tested for mass propagations of twoindigenous nematodes (H. indicus PLR2 and SteinernemaT96) and one commercial strain (S. carpocapsae #25).Varying levels of IJ yields were observed across thereplications and experiments. Medium F that contained 1.0%yeast extract, 2.5% egg yolk, and 4.0% soy oil yielded thehighest IJ numbers of H. indicus PLR2 (1.5×105 IJ ml-1) andof S. carpocapsae #25 (2.9×105 IJ ml-1), whereas the widelyused medium B, which is based on homogenized chickenoffal (40%), yielded the highest number of Steinernema T96(5.8×104 IJ ml-1). The IJ’s quality, as measured by theirmorphometrics and pathogenicities, were generallyimpaired, indicating the lack of essential nutrient(s) in themedia. Optimization of the propagation media is thereforestill needed to increase IJ’s quantity and quality to achievethe required standard for commercial scale of artificialpropagation.

Abstract

ABSTRACTAnalysis of Coat Protein Gene of Chilli Veinal MottlePotyvirus Collected from Several Means in Indonesia. IfaManzila, Sri H. Hidayat, Ika Mariska, and SrianiSujiprihati. Variation on symptoms and virulence wasobserved on different isolates of ChiVMV collected fromWest Java, Central Java, East Java, South Kalimantan, WestSumatera and Central Aceh. Research was conducted tostudy genetic variation of six ChiVMV isolates based onsequence analysis of coat protein (CP) gene and aminoacid. Sequence analysis of CP gene showed 87% to 99%homology among the six isolates with level of variationranging from 0.02% to 1.48%. Sequence analysis of aminoacid derived from CP gene showed 85% to 99% homology.Further analysis on amino acid motives of CP gene indicatedmutation of octapeptide motif, i.eLSGQVQPQSRQSEMETEVPQVR on ChiVMV CKB andRMETFGLDGRVGTQEEDTERHT on other ChiVMV isolates.Other differences was observed on amino acid number 61and 84 i.e. deletion of MET and mutation of GG to KV onChiVMV BL and KR. Phyllogenetic analysis based onnucleotide and amino acid sequence showed that sixisolates of ChiVMV can be differentiated into three groups.ChiVMV KR and BL were in the same group with ChiVMVPataruman (GeneBank No. access DQ854961), ChiVMV CKBwas in the same group with ChiVMV Cikabayan 2(GeneBank No. access DQ854960), and ChiVMV TD, ChiVMVNI and GB ChiVMV were in the same group with ChiVMVTaiwan (GeneBank No. access DQ854948). Analysis of CPgene confirmed the occurrence of genetic variation amongChiVMV isolates although symptom variation is weak.

Abstract

Plant breedersmake a succession of backcrosses to introgress a characterfrom a donor parent into genomic background of a recurrentparent. In several backcrossing, the proportion of a genometends to return almost fully to recurrent parent, except thesmall donor genome segment harboring the character ofinterest. The estimation of the proportion donor segmentthrough backcross generations has been analyzedtheoretically using complex mathematical simulations. Inthis study, the proportion of donor introgression segmentswere directly analyzed in advanced backcross populations,BC2F7 and BC4F2. The analysis was done by using a set ofsingle nucleotide polymorphism (SNP) markers covering theentire rice genome. Of the 384 SNP markers we found 124markers which provide polymorphism between recurrentparent, Way Rarem and Oryzica Llanos-5 as donor parent.But only 55 SNP markers could detect Oryzica Llanos-5alleles in BC2F7 and BC4F2 progenies. The result of thisanalysis demonstrated that the average of donor segmentnumber was 14.5 in BC2F7 and 12.3 in BC4F2. It was reduced15% from BC2F7 to BC4F2. The average of donor segmentlength was 31.2 cM (centiMorgan) in BC2F7 and 8.79 cM inBC4F2. It was decreased 72% during twice backcrossing. Theaverage of donor genome size was 343.95 cM in BC2F7 and71.35 cM in BC4F2, which means there was 79% decreasefrom BC2F7 to BC4F2. These results offered a simple methodto describe the proportion of target genome segment fromdonor parent. It was required as one of the main selectioncriteria in backcross programs.
