Abstract

Late blight resistance gene (RB gene) isolated from Solanum bulbocastanum, is a broad resistance gene against all races of Phytophthora infestans. The gene was transformed into Katah-din event SP904 and SP951 using Agrobacterium tumefaciens and these transgenic plants have been crossed with susceptible potato cultivars Atlantic and Granola. Populations of the crosses have been molecularly characterized for the integration of the RB transgene. The study aimed to evaluate the resistance of the populations of crosses between transgenic Katahdin RB  and susceptible non-transgenic parents (Atlantic and Granola) to late blight in a confined field trial at Pasir Sarongge, Cianjur, West Java. A total of 84 clones originated from four popula-tions were evaluated for resistance to late blight. These included 22 clones of Atlantic x transgenic Katahdin SP904, 16 clones of Atlantic x transgenic Katahdin SP951, 19 clones of Granola x transgenic Katahdin SP904, and 27 clones of Granola x transgenic Katahdin SP951. Observations of the late blight infection were conducted when late blight symptoms were detected, i.e. at 56, 60, 63, 70, and 77 days after planting (DAP). The result showed there were high variations in the resistance level of all the 84 clones tested. Clones of crosses between susceptible parents (Atlantic or Granola) and resistant parents (transgenic Katahdin SP904 or Katahdin SP951) showed a similar pattern based on the area under disease progress curve (AUDPC) value, i.e. 377.2 greater than the AUDPC of the resistant parents (180.1), but smaller than that of the susceptible parents (670.7). Observation at 77 DAP resulted four resistant potato clones having resistance score of 7.0-7.6, higher than the transgenic parents Katahdin SP904 (4.6) and Katahdin SP951 (6.8), i.e. clone B8 (Atlantic x transgenic Katahdin SP951) with resistance score of 7.6 and clones B26 (Atlantic x transgenic Katahdin SP951), C183 (Granola x transgenic Katahdin SP904), and D89 (Granola x transgenic Katahdin SP951) with resistance score of 7. These four transgenic potato resistant clones need to be further developed as promising potato clones to late blight.

Abstract

Propagation of Coffea arabica L. through direct and indirect somatic embryogenesis technique is promising for producing large number of coffee seedlings. The objectives of the research were to evaluate methods for direct and indirect somatic embryo-genesis induction of C. arabica var. Kartika. The explants were the youngest fully expanded leaves of arabica coffee. The evalu-ated medium was modified Murashige and Skoog (MS) medium supplemented with a combination of 2.26 µM 2,4-D + 4.54 or 9.08 µM thidiazuron; 4.52 µM 2,4-D + 4.54 or 9.08 µM thidiazuron; or 9.04 µM 2,4-D + 9.08 µM thidiazuron. Both calli (100 mg) and pre-embryos developed from the edge of leaf explants were subcultured into regeneration medium (half strength MS with modified vitamin, supplemented with kinetine 9.30 µM and adenine sulfate 40 mg L-1). The results showed coffee leaf explant cultured on medium containing 2.26 µM 2,4-D + 4.54 or 9.08 µM thidiazuron to induce direct somatic embriogenesis from explant, while that of 4.52 or 9.04 µM 2,4-D + 9.08 µM thidiazuron to induced indirect somatic embrio-genesis. The medium for calli induction from coffee by explants was medium supplemented with 4.52 or 9.04 µM 2,4-D in combination with 9.08 µM thidiazuron. On the other hand, the best medium for activation of induction of somatic embryos was MS medium supplemented with 9.04 µM 2,4-D + 9.08 µM thidiazuron. Based on this results, the first step for developing micropropagation for coffee has been resolved. The subsequent studies will be directed to evaluate agronomic performance of the derived planting materials.

Abstract

Potato late blight, caused by Phytophthora infestans is one of the most devastating plant disease. Potato yield losses due to this disease ranged from 47-100%. A major late blight resistance gene, called RB, previously was identified in the wild potato species Solanum bulbocastanum. RB gene has been integrated into cultivated potato Katahdin using Agrobacterium-mediated transfor-mation, and showed durable and broad spectrum resistance either in laboratory assay or in confined field trial. Evaluation of transgenic Katahdin SP904 and SP951 was conducted to verify whether the RB gene with broad spectrum to all known races of P. infestans in the United States and in Toluca, Mexico was also effective against P. infestans isolates in Indonesia. Efficacy of RB gene was evaluated for foliar and tuber resistance to West Java isolates. Transgenic Katahdin were more resistant in foliar than non transgenic plants, at 14 days after inoculation. Diseases intensity of transgenic Katahdin SP904 and SP951 were 19.8-43.8%, whereas non transgenic Katahdin, Granola, and Atlantic were 46.9-100%. In contrast to the foliar resistance phenotype, RB-containing tubers in transgenic Katahdin did not exhibit increased resistance to Lembang, Pangalengan and Galunggung isolates. Tubers of transgenic Katahdin SP904, SP951, and non transgenic Katahdin showed lesion volume of 0.93, 0.91, and 0.91 cm3, respectively. RB gene in transgenic Katahdin showed efficacy against late blight P. infestans in foliar, but did not showed efficacy in tuber. Transgenic Katahdin RB thus providing a potential source of resistance for breeding programs.

Abstract

Low productivity of shallot in Indonesia can be improved through development of high yielding variety. The availability of genetic information related to the character being improved is inevitable for effective breeding program. In this study, seven shallot genotypes were evaluated for their combining ability for yield improvement using half diallel cross.  Heterosis effect and heritability estimate was also investigated for yield-related characters.  The results showed that there were significant differences in general combining ability (GCA) and specific combining ability (SCA) among the evaluated genotypes. Tiron and Timor had the greatest GCA.  The greatest SCA and heterosis value was found in crosses of Kuning/Tiron, Timor/Bima Juna, Tiron/Timor and Kuning/Sibolangit. Heterosis effect varied from low to high. Broad sense heritability estimate for all characters was high, but narrow sense heritability was low for most charaters.  The dominant gene action observed on all yield-related characters suggests that the evaluated genotypes are potential to be used in breeding for high yielding hybrid varieties.   Keywords: GCA, SCA, heterosis, heritability, shallot

Abstract

ABSTRACTPreliminary study: Gene transfer from transgenic potato Katahdin RB to non transgenicpotato. One of the concerns associated with the release of transgenic crops, is the possibilityof the gene flow from transgenic crops to neighboring crops of the same species or to relatedspecies. In plants, gene flow is a routine process occur through the natural hybridization. Theopportunity for gene flow occur depends principally on two factors, the degree of sexualcompatibility between donor and recipient species, and the physical distance between thetwo. The experiment was conducted to determine whether the gene flow from transgenicpotato Katahdin RB to non transgenic was occurred, based on selection using a 50 mg/lkanamycin, and to estimate gene flow mediated by natural hybridization at different isolationdistances. Preliminary result indicated that a rapid and simple method using MS0 liquid mediawith kanamycin 50 mg/l was effective for screening the seeds. There was a gene flow fromtransgenic potato Katahdin RB to non transgenic, based on a rapid and simple selectionmethod using 50 mg/l of kanamycin as selectable marker. The isolation distance used in thestudy were 0.8, 1.6, 2.4, 3.2, 4.0, 4.8, 5.6, 6.4, 7.2, 8.0, 8.8, 9.6, 10.4, and 11.2 m from the row oftransgenic potato Katahdin RB. The gene flow through natural hybridization at a isolationdistances of (0.8 - 1.6 m), (2.4 – 4 m), and (4.8 – 6.4 m) from transgenic to non transgenic plantswere 13.78, 10.92, and 3.82%, respectively. At a distance of 7.2 – 8 m, the frequency of gene flowwas declined to 0%. The frequency of gene flow from transgenic potatoes to non transgenicpotatoes markedly decreased by increasing the isolation distance, and was negligible at 7.2 m.Key words : natural hybridization, transgenic potato RB, kanamycin selection

Abstract

INDUCTION MUTATION AND SELECTION OF IN VITRO PLANT OF WHEAT (Triticum aestivum L.)The goal of this research was to produce wheat crop which is tolerant to lowland condition.Six varieties were used, Dewata, Selayar, Alibey, Oasis, Rabe and HP1744. This research consisted of 4 stages: production of the best callus on MS medium containing 3 g/L 2.4-D, induced mutation of embryogenic callus using EMS, in vitro selection of callus at temperature of 27–35°C, and callus regeneration. The best result for callus production was 76% for Dewata and 70% for Selayar varieties. Higher concentration of EMS and longer soaking time decreased the percentage of callus growth. LC50 for Dewata was 0.3% EMS at 30 minutes and that for Selayar was 0.1% EMS at 60 minutes. The higher the temperature was, the lower was the adaptation tolerant of the plants, and callus growth was inhibited. At the highest temperature (35°C) the callus did not grow at all.Keywords: Induced mutation, Triticum aestivum, EMS, in vitro selection, callusABSTRAKTujuan penelitian ini adalah untuk merakit tanaman gandum yang toleran pada dataran rendah.

Abstract

The purpose of this study was to identify the selection criteria to obtain a superior mutant derived from the wheat plants of such varieties as Dewata, Selayar and Alibey, adaptive in medium land. The analysis of agronomic growth characters showed a significantly effect on a growth percentage of the initial growth (8 mutants), flowering time (1 mutant), panicle stem length (15 mutants), number of panicles (7 mutants), the number of grains per panicle (8 mutants), grain weight observed (8 mutants), grain weight per genotype (6 mutants), leaf area (2 mutants) and leaf greenness (5 mutants). The effects on the characters of ripe time, harvest, panicle length and plant height were not significant. The mutants of Dewata, Selayar and Alibey could be selected based on the characters of panicle stem length, number of grains per panicle and grain weight per observation because these characters generated more mutants than the other characters. The correlation analysis between the characters of growth and yield components of wheat mutants showed that the number of grains per panicle was positively correlated with the grain weight observed, while the length of panicle stem was positively correlated with grain weight per genotype, number of panicles and leaf area. Hopefully some mutants produced could adapt to the tropical medium land, thus adding to the diversity of wheat germplasm in Indonesia, thereby reducing the import of wheat to Indonesia.How to CiteSari, L., Purwito, A., Sopandie, D., Purnamaningsih, R. & Sudarmonowati, E.

Abstract

Tetraploid citrus are important for interploidal hybridization to create triploid seedless citrus.  Colchicine is the most commonly used as antimitotic agent to induce polyploid plants.  Tetraploid induction by colchicine in Pummelo ‘Nambangan’ was conducted in vitro using different types of explants.  The aim of this research was to induce tetraploid pummelo ‘Nambangan’ by colchicine treatment using germinated seed, shoot tip and cotyledonary node as explants.  Tetraploid shoot induction was conducted by soaking germinated seeds, shoot tips and cotyledonary nodes in 0.1% colchicine for 1, 3 and 5 h.  Regenerant shoots were grown on MS medium and their growth was observed after four weeks in culture.  Ploidy level was determined using flow cytometry analysis.  Stomata density, length and width of stomatal guard cell were also recorded. The results showed that shoot elongation was inhibited by colchicine treatment.  Soaking of shoot tip explants in 0.1% colchicine for 1 h resulted in 66.66% of putative tetraploid shoots.  Compared to diploid shoots, tetraploids had lower stomata density but bigger in guard cell size. Keywords: colchicine, tetraploid, pummelo (Citrus maxima (Burm.)

In Vitro Multiplication of  Black Orchid (Coelogyne pandurata Lindl.) Using the Combination of NAA and BAPABSTRACTBlack orchid is an indigenous plant from Kalimantan, Indonesia. It becomes endangered because of forest over-exploitation and its low natural reproduction rate. Tissue culture is considered to offer a solution to conserve and propagate this species. The aim of this research was to evaluate the effect of Naphtalene Acetic Acid (NAA) and 6-Benzile Amino Purine (BAP) on shoots multiplication of black orchid. The basic medium used was a half of Murashige & Skoog (MS) composition supplemented with 150 mLL-1 coconut water. Initial explants used were 6-month-old shoots of germinating seeds. The shoot cultures were incubated for 23 weeks. Results showed that the best combination for shoot multiplication was NAA 0.0 mgL-1 with BAP 0.2 mgL-1. Shoot grew better on medium with BAP and without NAA while roots growth was better on medium without the two plant growth regulators. The addition of BAP up to 0.3 mgL-1 increased the leaf number, which however decreased at higher BAP concentration.Keywords: BAP, black orchid, Coelogyne pandurata, multiplication, NAA ABSTRAKAnggrek hitam merupakan flora langka asli Kalimantan, Indonesia. Keberadaa anggrek ini di alam semakin langka akibat eksploitasi berlebihan dan sulitnya perbanyakan secara alami. Kultur jaringan merupakan metode untuk mengatasi kelangkaan anggrek ini. Penelitian ini bertujuan untuk mengetahui pengaruh kombinasi NAA dan BAP terhadap multiplikasi anggrek hitam. Media dasar yang digunakan adalah ½ MS dengan penambahan air kelapa 150 mLL-1.
