Abstract

Rice (Oryza sativa L.) is largely cultivated in lowland area that vulnerable to flood occurrence. Root supposed to play an important role on rice tolerance to submergence stress. An experiment which conducted from January to May 2014 in Cikarawang Field Laboratory, Darmaga, Bogor, West Java aimed to study the role of root distribution on rice submergence tolerant. The experiment used Split Plot design replicated three times, with the depth of submergence as main plot and rice variety as subplot. The main plot consisted of  water depth of 5 cm (optimum), 50 cm, 60 cm and 80 cm from soil surface. The subplot consisted of four rice varieties, namely Ciherang, Inpari 30 (Ciherang Sub1), Indragiri and Margasari. Each plant was planted in a root box (30 cm x 40 cm x 5 cm) which put into container (67 cm x 47 cm x 42 cm) and placed into the pond with water depth as treatment. Submergence started when the plant was 39 DAS (Days After Seeding) for ten days. Observation conducted after the submergence stopped (49 DAS). Result showed that submergence retarded plant growth, root distribution and increase root damage for all rice varieties with the biggest effect on susceptible varieties.

Abstract

One possibility to protect the maize from storage pests is by developing genotypes that resistant to maize weevil (Sitophilus zeamais Motsch). The research was aimed to evaluate the susceptibility of several maize genotypes including local variety to the maize weevil. Six genotypes i.e. SJA, G10-12-20, G10-1-3, G10-1-7, G10-1-20 and G10-1-17 and Tosari as local variety were used. No-choice assay under laboratory condition with observed variables was laid an egg and F1 progeny number, the median time of development and weight loss of infested kernel. The susceptibility index was assessed using Dobie’s susceptibility index. Results showed that the number of eggs laid by five females and infested samples weight loss were not significantly different between six maize genotypes as well as local variety. In contrast, the number of F1 progeny emerged was significantly different. Based on the susceptibility index, the maize genotype of G10-1-3 and G10-1-17 were resistant to the weevil. While other maize genotypes and local variety were considered as moderate resistant. Based on analysis of chemical and physical characteristic revealed that maize genotypes with higher of the total phenolic compound and physical hardness tend to resist from weevil damaged.

Abstract

Stevia rebaudiana Bertoni originally from Paraguay belongs in Asteraceae family. It is an alternative source of non-caloric sweetener due to the sweet steviol glycosides contained in the leaves. As an introduced species in Malaysia, it is important to elucidate the genetic variabilities and relatedness among stevia accessions in order to broaden the genetic basis for future stevia breeding. This study described morphological and chemical variations and investigates genetic relationships among stevia accessions derived from across Malaysia and Paraguay using inter simple sequence repeats (ISSR) markers. HPLC (high-performance liquid chromatography) analysis also revealed high variability with stevioside content between 4.54 % (Taman Pertanian) to 20.36 % (Bangi) and rebaudioside A content varied between 0.3 % (Nilai) to 2.04 % (MNQ). From 32 ISSR markers, a total of 332 bands were scored, of which 264 (78 %) were polymorphic. The dendrogram from UPGMA (Unweighted Pair Group Method with Arithmetic Mean) cluster analysis separated 17 stevia accessions into 3 main groups. Rawang and Nilai were found to be closely related. The wide genetic variabilities among stevia accessions are a promising indicator towards the development of new stevia varieties. This valuable information will be able to assist parental selection in future stevia breeding programmes.

Abstract

Protoplast fusion is a useful technique for citrus genetic improvement. Establishment of protoplast technology could produce triploid seedles citrus and new citrus genetic combination. The aim of this research was to establish protoplast isolation, protoplast fusion between pummelo ‘Nambangan’ (Citrus maxima) and keprok ‘Garut’ (C. reticulata), and its protoplast culture. Protoplasts were isolated from leaves of in vitro seedlings of pummelo ‘Nambangan’ and embryogenic callus of keprok ‘Garut’ with two different compositions of enzymes. The results showed that optimum enzymes compositions for cells mesophyl wall degradation were consisted of 0.5 % Onozuka cellulase RS10, 0.5 % Macerozyme R10 and 0.1 % Pectolyase Y23. Optimum enzymes composition for callus embryogenic cells wall degradation were 0.5 % Onozuka cellulase RS10 added with 0.5 % Macerozyme R10. Protoplast fusion was conducted with PEG-mediated. Protoplast mixture were incubated in 40 % PEG for 8-10 min and after that could be observed 40.6 % of unfused protoplasts, 4.6 % of homofused mesophyl protoplasts, 28.2 % of homofused callus protoplasts, 7.8 % of heterofused and 9.6 % of multifused protoplasts from mesophyl and callus. Cells divided at the first week and began to form cell colonies afterwards in liquid culture.

Abstract

The accession of the IRDB 1981 (PN’81) population is a newly introduced and an important rubber tree germplasm while the Wickham clone is a commercial variety one. The objectives of this study were to assess the genetic diversity and the population structure of PN’81 populations and the Wickham clones using 15 EST-SSR loci. Results of the analysis showed that the evaluated SSR primers yielded polymorphic markers. The gSSR 268 primer pairs yielded the most informative markers while HBE 280 primers generated the lowest ones. Results of the genetic diversity analysis supported that the PN’81 population belonged to a single large natural population of rubber trees while the Wickham clones belonged to a different group than that of PN’81. The population structure analysis of the rubber accessions was also in agreement with the results of the genetic diversity analysis. The experiment also indicated that PN’81 populations would be useful for future rubber breeding in Indonesia, especially as the sources of parent clones for rubber tree hybridization programs and rubber tree genetic resource conservation.

Abstract

Curvularia lunata was found to cause a serious rice brown leaf spot in Cambodia. This is the first report of brown leaf spot on rice in Cambodia. All isolates were tested for pathogenicity. Dual culture antagonistic tests showed that Chaetomium cupreum inhibited sporulation of C. lunata when compared to the control. In a pot experiment, C.  cupreum significantly reduced the incidence of brown leaf spot caused by C. lunata. After application of a spore suspension of C. cupreum, Chaetomium-biofungicide and chemical fungicide (tebuconazole) to rice seedlings inoculated with C. lunata, the disease was reduced by 68.79 %, 75.80 % and 72.41 %, respectively. In a field trial, the chemical method gave the best results in all plant parameters, followed by the good agricultural practice (GAP) and organic methods. The chemical method gave the highest panicle/plant, panicle length, panicle weight, grain weight/plant which were different from the GAP and organic methods. The chemical method also gave the best results in filled grain panicle-1, unfilled grain panicle-1, grain weight plot-1, dry hay weight plot-1, biomass weight plot-1 and harvest index, and was significantly better than the GAP and organic methods.

Abstract

The objective of this research was to determine the diversity and relationship of sapodilla accession derived from districts in DIY based on DNA profiles. From the screening of 20 total primers, five primers (OPA 20, OPB 5, OPB 6, OPB 8, and OPC 19) producing polymorphic bands in RAPD analysis were selected. Different-shaped samples of sapodilla randomly collected from Bantul, Gunungkidul, Kulonprogo, Sleman and Yogyakarta city were used in this research. The analysis of molecular data was performed by using NTSys pc-2.02 and GenAlex 6.1 program. The clustering indicated that the accessions tend to group by their locations. However, there was no corelation between DNA marker and the fruit shape. The first group comprised samples from Yogyakarta city (Keraton Yogyakarta), Bantul and Kulonprogo while the second group consisted of samples from Sleman and Gunungkidul with genetic similarity of 53% and 37% respectively. The genetic diversity was high (PLP = 98.85% of 87 loci and H=0.280±0.14) comprising the genetic diversity within population (53%) which was greater than genetic diversity between populations (47%). Having the highest genetic diversity, Gunungkidul should be potential for conservation and selection of sapodilla in DIY.

Abstract

The study aimed to determine the response of two local rice cultivars subjected to different doses of nitrogen (N) fertilizer in two paddy fields, namely Petung and Gunung Makmur in Penajam Paser Utara, East Kalimantan. The research was arranged in Nested Design with five doses of N fertilizers, two cultivars, and two locations as treatments. The doses of N fertilizers were 0, 25, 50, 75 and 100 kg N.ha-1 nested in two cultivars (Nanung and Pance Kuning) and two locations (Petung and Gunung Makmur). Each treatment was conducted in three replicates. The result showed that the Pance Kuning cultivar was superior than Nanung in Petung location in terms of the number of tillers per hill, number of productive tillers per hill, percentage of filled grain per panicle, weight of 1000 grains and potential yield. A different effect of N fertilizer was observed on the number of tillers per hill, percentage of filled grain per panicle and weight of 1000 grains. Nanung and Pance Kuning showed positive responses to the application of 75 kg N.ha-1 in Petung for the parameters of tiller number and weight of 1000 grains.

Abstract

The anthracnose pathogen was isolated from coffee leave and bean symptoms. Morphological and molecular phylogenetic data confirmed the species as Colletotrichum gloeosporioides. The pathogenicity of the isolate was also confirmed by detached leaf method which inoculated the virulent isolate into coffee leaves. The crude extracts with hexane, ethyl acetate and methanol solvents from Chaetomium cupreum CC3003 resulted significantly inhibited C. gloeosporioides that the ED50 values of 13, 11 and 28 ppm, respectively. The bioactive substances of C. cupreum CC3003 expressed antifungal activity against C. gloeosporioides as can be seen in the abnormal appearance of spores. A powder bio-formulation of C. cupreum significantly resulted to reduce anthracnose disease of 54.77 %. The application of nano-rotiorinol, nano-trichotoxin and a spore suspension of C. cupreum reduced anthracnose incidence of 46.23, 42.71 and 18.59 %, respectively while the inoculated control had high anthracnose disease. The application of bio-formulation of C. cupreum in powder form, nano-rotiorinol, and nano-trichotoxin to reduce coffee anthracnose was reported for the first time in Lao PDR.
