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

ABSTRACTThe fruit of ornamental chili functioned as ornamental as well as for consumption, and therefore it requires diversity of traits for selection process. Information on inheritance pattern of the traits are needed for effective selection. The ideotype of ornamental chili are shortened internode that form a bouquet of flowers, erect fruit orientation and contain anthocyanins for attractive appearance. The research was aimed to study qualitative characters inheritance associated with shortened internode, fruit orientation and anthocyanins content. This study used 6 population including female parent (P1) which has anthocyanin in flower parts, the male parent (P2) bird pepper which has the character of a shortened internode, F1, F1R, BCP1, BCP2, and F2. Data were analyzed with Chi-square test to determine the Mendelian ratio in the F2 population. The results showed that there were characters that was controlled by one gene or two genes. Shortened internode and erect fruit orientation were controlled by a single recessive gene with a ratio of 1:3. On the other hand the color of anthocyanin in the anther stem was controlled by one dominant gene with a ratio of 3:1. The characters controlled by two genes that were dominant and recessive epistasis was the color of anthocyanins in the anther with the ratio 13:3.Keywords: Mendelian ratio, antosianin, shortened internode

Abstract

ABSTRACTThe use of high quality seed is one of the key factors to improve productivity. Probiotic bacteria has been used to increase plant growth and to control pathogens. The objective of the research was to evaluate methods of chili seed production that yielded high physiological and pathological quality using probiotic fluorescent bacteria Pseudomonas (P24). The bacteria was expected to function as plant growth promoting bacteria as well as capable of controling seedborne pathogen Colletotrichum acutatum causes antrachnose. The experiment was conducted during March until October 2014 in Seed Health Laboratory, Plant Bacteriology Laboratory, and Leuwikopo experimental garden, IPB. The experiment was arranged in a split plot randomized complete block design with three replications. The main plots were untreated and inoculation of C. acutatum. The subplot was six treatments of fluorescent Pseudomonas (P24) application. The results showed that matriconditioning and spraying of fluorescent Pseudomonas (P24) on nursery decreased disease incidence significantly. Matriconditioning and spraying of fluorescent Pseudomonas (P24) on nursery and flowering phase increased number of healthy fruit and total weight of seeds per plant significantly. These applications also increased seed physiological  quality indicated by germination percentage (GP) 77.04%, growth rate (GR) 9.72% etmal-1, vigor index (VI) 29.74%, and seed health by suppresed C. acutatum infection up to 12.25%.Keywords: anthracnose, Colletotrichum acutatum, control, matriconditioning, spraying

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

ABSTRACTCurcuma aeruginosa Roxb., popularly known as “temu ireng”, is considered as a potential source of medicinal plant for pharmacological activities. However, varieties of C. aeruginosa are still limited in Indonesia so it needs more accessions for improvement and development of new varieties. Rhizome colors, phytochemical contents and extract yield from 20 promising lines of C. aeruginosa were investigated by qualitative method for rhizome colors and phytochemical contents, and maceration method using 70% ethanol for yield extract. Similarity analysis was used for cluster analysis based on rhizome colors, phytochemical contents and yield extract. Blue was the color characterization of rhizome C. aeruginosa. The extract yield for 20 promising lines of C. aeruginosa varied from 7.92 to 19.71%, with KN and BH promising lines having the lowest and highest value, respectively. All promising lines of C. aeruginosa contain saponin and triterpenoid. Based on similarity analysis, all promising lines could be divided into 3 clusters. Cluster I consisted of 14 promising lines i.e. WG, SH, KA, GD, BH, KP, NW, PW, MB, PR, PT, KN, MD, and PK. Cluster II consisted of 4 promising lines i.e. LC, CB, KL, and GK. Cluster III consisted of 2 promising lines i.e. KD and SG. Keywords: promising lines, saponin, triterpenoid

Abstract

ABSTRACTSugarcane cultivars tolerant to drought stress are needed for specific location. In vitro selection can be used to obtain plants tolerant to drought stress through regeneration of callus in the culture medium. The purpose of this study was to obtain regenerants from irradiated callus on the stress medium. The experimental design was a completely randomized design with two factors. The first factor was the regeneration medium (RG) added with PEG 6000, i.e., 0%, 5%, 10% and 15%, while the second factor was the dose of gamma ray irradiation i.e. 0 krad, 5 and 10 krad, and 15 krad. There were 12 treatments, each treatment was repeated 18 times and each repetition was a culture bottles planted with three clums of callus 10 mm diameter. RG medium was the MS medium added with 0.5 mg L-1 BAP, Kinetin 0.1 mg L-1 and IBA 1.0 mg L-1. The higher the concentration of PEG, the less regenerants were produced. Regenerants could be generated from the selection medium PEG up to 15%. Several shoots still produced from callus irradiated with 10 krad. Selection medium with PEG up to 10% decreased the precentage of albino regenerants. The gamma ray irradiation dose and the concentration of PEG significanly affected the number of  roots produced.Keywords: drought tolerant, in vitro, polyethylene glycol, plantlets, albino

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

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

ABSTRACTDeveloping of  drought tolerant hybrid rice varieties requires parental lines which have tolerance to drought. Polyethylene glycol (PEG) has been widely used as an osmotic solution for detecting drought tolerance at germination stage of rice. The objectives of this experiment were to evaluate variables of drought tolerance at germination stage  and to select drought tolerance of parental lines using osmotic solution PEG 6000 at concentration of 25%. The experiment was conducted at the greenhouse ICABIOGRAD Cimanggu Bogor, during April-May 2014. The design of the experiment was arranged in factorial randomized block design with three replications. The first factor (genotype) had 21 levels and the second factor (osmotic potential) had two levels (0 and 25% concentration levels of PEG 6000). Based on the principal component analysis, six primary indicators were proposed for drought tolerance of rice at germination stage, i.e., germination percentage, seed vigor, seminal root length, seedling length and dry weight of seminal root. Based on the clustering analysis, at 73.76% of similarity rate, the 21 tested genotypes were divided into 2 groups. The genotypes which showed similar responses with Salumpikit were IR 58025B, GMJ 14B, IR 80154B, GMJ 15B, R 3, PK 90, and PK 12 respectively. Keywords: drought tolerance, germination, hybrid rice PEG, parental lines
