Abstract

ABSTRACTHaploid breeding through anther culture allows shortening of the breeding cycle and production of homozygous lines from a segregating population in the immediate generation. This technique has been used for crop improvement especially in rice. The objective of this research was to determine regeneration ability of twelve F1s, derived from reciprocal crossing between high yielding rice variety and rice tolerance to salinity, through anther culture. Completely randomized design with 20 replications was used in this research. Medium for callus induction was based on N6 medium + 2.0 mg NAA L-1 + 0.5 mg kinetin L-1 + 1 mM putrescine, while regeneration medium was based on MS + 0.5 mg NAA L-1 + 2.0 mg kinetin L-1 + 1 mM putrescine. Rooting were done in MS medium + 0.5 mg IBA L-1 + 1 mM putrescine. The result indicated that F1 derived from IR77674/Inpari 29 (3.1% green plants/total anther) was the most responsive genotypes in rice anther culture (high anther culture ability). After greenhouse grow out 125 putative double haploid plants were obtained (41.5% from total acclimated green plantlets).  Keywords: double haploid, green planlets, indica rice, salt tolerance

Abstract

ABSTRACTSomatic embryo induction medium was reported to be genotype dependent for soybean. This study was aimed to obtain the optimum medium for embryo somatic induction and proliferation, and to regenerate somatic embryo of five soybean genotypes. Five soybean genotypes (Tanggamus, Anjasmoro, Yellow Biloxi, CG-22-10, and SP-10-4) were used in this study. The research was divided into four steps: (1) embryogenic callus induction of  five soybean genotypes, (2) embryogenic callus proliferation of five soybean genotypes, (3) optimation of embryo somatic induction on five soybean genotypes and (4) embryo somatic regeneration of five soybean genotypes. The induction experiment showed that based on number of embryogenic callus, the best somatic embryo-induction medium was 3% sucrose+ NAA 5 mg L-1+2,4-D 5 mg L-1+ Vitamin B5. Embryogenic callus number for each genotype tested was increased on proliferation media of 3% sukrosa + 2,4-D 5 mg L-1 + NAA 5 mg L-1+ Vit B5, and Yellow Biloxi gave the highest number of proliferated somatic embryos compared to other genotypes. Increasing number of globular somatic embryo of all genotypes was obtained from the optimation of somatic embryo induction media being used, and Tanggamus genotype gave the highest number of globular somatic embryo which followed by Yellow Biloxi genotype. Tanggamus and Yellow Biloxi genotypes were also successfully formed the four steps of somatic embryos (globular, heart, torpedo, and cotyledonary stages), but in regeneration medium of MS0 and media MS + sukrosa 10 g L-1 + GA3 2 mg L-1 + BAP 4 mg L-1 + Vit B5 only Tanggamus genotype was regenerated into plantlet.  Keywords: 2,4-D, NAA, somatic embryos, induction, proliferation

Abstract

ABSTRACTBambara groundnut (Vigna subterranea L. Verdc.) is an important underutilized legume crop in Indonesia. The aim of this research is to study genetic diversity of bambara groundnut from Sukabumi and Sumedang, West Java, Indonesia. This study used 107 bambara groundnut accessions, which consisted of 57 accessions from Sukabumi and 50 accessions from Sumedang. We use five simple sequence repeat (SSR) to analyze the accessions. Totally nine alleles were detected, with a mean of 1.8 alleles per locus. Allelic and gene diversities were higher in Sumedang (1.8 alleles per locus and 0.119) than in Sukabumi population (1.4 alleles per locus and 0.020), respectively. We constructed a phylogenic tree by Neighbor-Joining analysis based on genetic distances (DA) and showed the tree divided bambara groundnut accessions into two broad groups according to the origin of samples (Sukabumi and Sumedang). Results from the phylogenic tree are in line with those from the population structure analysis. Keywords: allele diversity, bambara groundnut, genetic distance, under utilized legume

Abstract

ABSTRACTAn effective and efficient in vitro propagation system has important roles in preparing and producing high quality-seedlings of Dendrobium for commercial scale. The objective of this research was to establish an effective and efficient embryogenic callus (EC) proliferation method using bioreactor system and regeneration EC into plantlet for producing high quality seedlings of Dendrobium Indonesia Raya ‘Ina’. Differences in callus densities (5, 10, 15, and 20 g callus in 250 mL medium), aeration levels (2.5, 5.0, and 10.0 O2 volume  per  medium volume per minute; vvm), and regeneration media half-strength MS and 2 g L-1 NPK (32:10:10) combinated by 0.00, 0.05 mg L-1 BA, 150  mL L-1 coconut water and their combinations were tested in this experiment. The experiments were arranged using randomized completely block design (RCBD) with three replications for EC proliferation and randomized completely desaign (RBD) for EC regeneration. The results showed that combination of  aeration at 2.5 vvm and 10 g of EC was the most suitable aeration level and callus density for proliferation of EC in the 500 ml airlift bioreactor with 6.85 multiplication rate, 92.5% EC formation, and malformed callus morphology as low as 6.1%. The highest somatic embryos (SEs) formation was 87.7% with 44.5 SEs per clump and 92.1% SEs germination with 41.0 germinated-SEs per clump, 85.1% normal germinated-SEs, and whereas the best performance of plantlet was obtained from 1/2 MS + 0.05 mg L-1 BA semi solid medium. Plantlets were successfully acclimatized using Cycas rumphii medium with high survival rate (91.6%). Keywords: aerations, callus densities, germination, media, somatic embryos

Abstract

ABSTRACTNutrition  pumps  pressure is important in aeroponic. Optimal  pump  pressure produces well oxygenation, so that increases the dissolved oxygen content in the nutrition. It is good for plant roots. The purpose of this study was to determine pump pressure on the growth and yield  potato seeds grown in aeroponics in lowland 125 m asl with root zone cooling. This study used a randomized block design non factorial. Data were analyzed using analysis of variance followed by a further test of orthogonal contrasts at the level of α = 5%. Results showed that different pump pressure on the provision of nutrient, temperature cooling in the root zone gave different results on the number of potato tubers per plant and weight per tuber in each variety. Root zone cooling temperature 15 °C, the pump pressure> 1.5 atm produce highest number of tubers per plant, i.e. 11.8 tuber of Granola variety and 8.2 tuber of Atlantic variety.  The was no tuber produced from control (without referigeration). The highest weights per tuber (10.35 and 5.01 g for Atlantic and Granola variety, respectively) were reached with cooling temperature at 15 °C and the pump pressure > 1.5 atm.Keywords: evaporative cooling, hydroponics, potato, tuber, variety

Abstract

The genetic transformation via pollen-tube pathway in jatropha is the first alternative method that was applied in this plant. The objective of the research was to study fruit set and germination of three genotypes of jatropha following direct transformations via pollen-tube pathways. The research was conducted during April 2014 until January 2015 at jatropa’s experimental field, Pasuruan, and at green house of ICABIOGRAD, Bogor. Three genotypes of jatropha i.e., IP3A, IP3P and JcUMM18 were used. In the first experiment, split plot design was used where 3 levels of DNA plasmid concentration as a main plot and 5 levels of stigma-drip time of DNA plasmid as a subplot. In the second experiment randomized block design was used with single factor consisting of 15 combinations of concentration and stigma-drip time of DNA plasmid as treatments and control. The results demonstrated that interaction between concentration and application time of DNA plasmid did not significantly affect fruit and seeds formation of three Jatropha genotypes. Combination of DNA plasmid concentration with time of stigma-drip had significant effect on seed germination rate of IP3A genotype, but not significant on the other variables. The concentration of 0.05-0.5 µg µL-1 and application time of DNA plasmid at 1-10 hours after pollination could be applied on jatropha genetic transformation via pollen-tube pathways.Keywords: DNA plasmid, Jatropha curcas, pCAMBIA1301, pollen-tube, stigma-drip

Abstract

Bacterial soft rot disease because of Dickeya sp. infection is the main problem in Phalaenopsis production in Indonesia, but the percentage of infected plants has never been recorded in detail. Isolation and characterization of Pto gene from Phalaenopsis could be useful to support breeding for resistance Phalaenopsis. Encoding serine-threonine kinase, Pto gene confers resistance to bacterial infection of Pseudomonas syringae in tomato. The objectives of this study were to isolate, sequence and characterize fragment of Pto gene from 20 genotypes of Phalaenopsis (16 species and 4 hybrids) and to evaluate their molecular diversity. Genomic fragments of Phalaenopsis were amplified using Pto specific degenerate primers; and the PCR amplicons were sequenced. Searching the identity of determined sequences was done using BLAST against all accessions in NCBI GenBank DNA database and in Conserve Domain Database. PCR amplification using Pto specific primers produced a single DNA fragment of ~500 bp. The determined nucleotide sequences from the amplicon were ~449 bp. The nucleotide sequences of the amplicons from 20 Phalaenopsis genotypes showed high sequence identity to Pto from Musa acuminata. Translation of the amplicon results in ~149 amino acid residues. Comparison of the translated polypeptides identify indicated there were low variations of Pto gene among accessions since they contain the PTO catalytic domain and the Serine/Threonine kinases, sub family of Interleukin-1 Receptor Associated Kinase (STK_IRAK) which are the conserved domains for PTO.Keywords: catalytic domain, disease resistance, fragment Pto gene, phylogenetic, RGA

Abstract

ABSTRACTThe morphophysiology of ratoon is different from the main plant of rice and was influenced by location and cultivation.This research was intended to evaluate morphophysiology characters of rice ratoon planted by direct seeding system in tidal swamp at various stubble cutting height. The experiment was conducted in November 2013-April 2014 at tidal swamp overflow type B in Telang Sari Village, District of Tanjung Lago, Banyuasin, South Sumatra Province. The experiment used randomized block design with 5 replications. Treatment was stubble cutting height 10, 20, 30, 40 and 50 cm above the soil surface. Rice was planted at 4 m x 5 m plot, the distance between plot 1 m. Data were analyzed by test of variance and 5% HSD test. Morphophysiological characters of rice ratoon were influenced by stubble cutting height. Cutting height of 20-40 cm above soil surface increased the ratoon number of tillers per hill, leaf area per hill, dry weight per hill, percentage of empty grains per panicle, grain weight per hill and percentage ratoon/main crop production per hill. The higher stubble cutting, the lower the number of leaves per tiller, leaf area per tiller, carbohydrate content, and number of grains per panicle of ratoon, however it accelerated age of flowering and harvesting. Keywords: direct seeding system, ratoon system, rice growth and production, stubble cutting height

Abstract

The genetic transformation via pollen-tube pathway is an alternative method to overcome the constraints imposed by genotype specificity in transformation and regeneration in jatropha (Jatropha curcas L.) tissue culture. Therefore, it is necessary to establish important parameters for efficient genetic transformation of jatropha via pollen-tube pathway. The objective of the research was to study the efficiency of direct transformation of jatropha via pollen-tube pathway based on histochemical and molecular analysis. Solution of purified pCAMBIA1301 DNA plasmid carrying a hptII marker gene and a gus reporter gene with concentration level of 0.05, 0.25, 0.50 µg µl-1 were applied to stigma of flowers at 1, 2, 4, 7, 10 h after pollination. Seedling of IP3A, IP3P and JcUMM18 jatropha’s genotypes derived from 15 combination treatments of plasmid DNA concentration and application time, also wild type was subjected to histochemical and molecular analyses. Based on those analyses, the efficiency of transformation via pollen-tube pathway of three jatropha genotypes ranged from 1.5-16.7%. PCR analysis showed that a number of positive plants were identified by using specific primers hptII and gus, i.e. 1-3 and 3-7 plants of the 15 combined treatments, respectively. It indicated that the transformation efficiency via the pollen-tube pathway varied in each jatropha genotype.Keywords: Jatropha curcas L., pCAMBIA1301, plasmid DNA, stigma-drip
