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

Abstract

ABSTRACTThis experiment is a further development of several previous studies on the potential of Bacillus subtilis 5/B and Pseudomonas diminuta A6 (rhizobacteria), and Aeromonas sp. F112 (phyllobacteria) as biological agents. Research aimed to evaluate the application of biological agents to promote plant growth and to control bacterial leaf blight (BLB) disease in rice seed production. This research consisted of two experiments, the first was in the nursery while the second was in the field. The first experiment conducted in a completely randomized  design with one factor (seed treatments) and three levels, i.e., control (untreated), matriconditioning + streptomycin sulphate 0.2% (BsM), biomatriconditioning + B. subtilis 5/B + P. diminuta A6 (BM). The second experiment was conducted in a randomized complete block design with one factor (biological agent aplication methods) and nine levels, i.e., control (untreated), matriconditioning +  streptomycin sulphate 0.2% (BsM), biomatriconditioning + B. subtilis 5/B + P. diminuta A6 (BM), soaking of seedlings root with  B. subtilis 5/B + P. diminuta A6 (RA), foliar spraying with Aeromonas sp. F112 (SD), BM + RA, BM + SD, RA + SD, BM + RA+ SD. The result showed that seed treatments significantly increased field emergence. Eventhough all treatments did not significantly affect plant growth, incidency and severity level of BLB disease, and yield components, biomatriconditioning showed a better improvement in yield components. The seeds produced from plants treated with the biological agents showed significantly higher vigor index than untreated and matriconditioning + streptomycin sulphate 0.2%.

Abstract

The management of P nutrition can be a good solution for aluminum toxicity and P nutrient deficiency in acid soil. This study aimed to determine the role of phosphorus in improving the tolerance of sorghum to Al stress in nutrient culture. This research was conducted at green house of IPB Bogor, tissue culture laboratory in the Department of AGH IPB and Balai Besar Pasca Panen Cimanggu Bogor, from January to November 2014. A completely randomized factorial design was used in three experiments. The results revealed that addition of P improved the tolerance of two sorghum genotypes to Al stress as indicated by the reduction in root length inhibition by Al, where  P was more effective in tolerant genotype Numbu. Addition of P reduced the accumulation of Al in the root tissues as shown by the lighter intensity of hematoxylin staining, especially in Numbu. Aluminum stress increased the secretion of oxalate acid in both sorghum genotypes, where P lowered oxalate acid secretion in both genotypes. These facts showed that the role of P in improving the tolerance of sorghum to Al stress might be associated with the inhibition of Al absorption into the root tissues, although the mechanism is not yet known.Keywords: Al stress, organic acid secretion, role of P, root staining method, sorghum

Abstract

Oil palm is a perennial oil crop that contribute the most important source of vegetable oil in the world. Oil palm breeding cycle take a long period, therefore molecular marker-assisted selection (MAS) is required to shorten the selection time. This MAS require the associated marker to desired trait, particularly for yield and the component that as a complex trait and depend on genetic background. The aim of this study was to obtain SSR marker that associated with average of bunch weight (ABW). Plant material was used in this study is Tenera population derived from Deli Dura x AVROS Pisifera. Seven SSR markers from public database were associated to ABW trait. Molecular data analysed for SSR markers profile which consisted of allelic diversity, heterozygosity level, and polymorphism information content (PIC). Association between SSR markers to ABW traits was performed with single marker analysis using one way analysis of variance. The results showed that SSR markers were able to amplify DNA with two to three number of alleles with the average of 2.3 alleles per locus. ABW trait for this population was significantly associated with mEgCIR3428 marker. This marker may be used in the selection of Deli Dura and AVROS Pisifera palm on the next selection cycle.Keywords: Average of bunch weight, AVROS Pisifera, Deli Dura, single marker analysis

Abstract

Identification of Indonesia sugarcane varieties tolerant to waterlogging has not been done extensively. Information on varieties tolerant to waterlogging is required for seedling establishment in waterlogged areas. The purpose of this research was to identify the sugarcane varieties responses to several duration levels of waterlogging at seedling stage. The planting materials used were collection of Sugar Factory Semboro including VMC 76-16, BL, PS 862, PS 864, and PS 881. This research was arranged in randomized complete block design (RCBD) with two factors and three replications. The first factor was 5 varieties; the second factor was waterlogging treatment with four levels, i.e. without waterlogging, 2, 4, and 6 weeks of waterlogging in the bucket. The results showed different level of tolerance to water logging among the varities. PS 881 and VMC 76-16 varieties were the most tolerant to waterlogging supported by its ability to maintain plant height, root volume, root and shoot dry weight after been waterlogged for 6 weeks. These varieties were also able to establish aerenchyme tissue and increased the stomatal density. PS 862 was the least tolerant variety to waterlogging. Keywords: aerenchyme, morphology, stomatal density, waterlogging, water stress

Abstract

Knowledge of the magnitude of genetic variability, heritability and genetic advance in the selection of desirable characters could assist the plant breeders in ascertaining criteria to be used in the breeding programmes. Twenty three introgressed oil palm progenies were evaluated at the Specialized Centre for Oil Palm Research of Cameroon, from 2004 to 2014 to estimate performance, genetic variability, heritability and genetic advance of oil yield and some economic traits in terms to select new oil palm parent materials with the traits of interest. The results revealed high variability among oil palm population for all the characters. Moderate estimates of the phenotypic and genotypic coefficient of variations associated with high heritability and moderate genetic advance as percent of mean were obtained for characters of fresh fruit bunch, bunch number, oil yield, kernel to bunch, kernel to fruit, kernel yield and height increment. The results suggest the effectiveness of selection method for these traits and their improvement through their phenotypic performance. LM11087T x LM2749D and LM12960T x LM7409D were obtained as superior oil palm crossing parents with the potential production of 6.26 ton ha-1yr-1 of crude palm oil; they can be exploited in seed production and further breeding program.Keywords: genetic advance, heritability, introgressed progenies, oil yield, Phenotypic

Abstract

Anther culture is one of tissue culture methods which can be applied to plant breeding programs in order to accelerate the process of obtaining pure lines. The successful development of rice varieties is highly dependent on genetic diversity and desirable traits. To obtain the genetic variability of doubled haploid lines through anther culture techniques, anther F1 or F2 were used as explants sources. The objectives of the study were to select and characterize doubled haploid lines of upland rice having the characters of new plant type, and to study the genetic variability and agronomic characters of tested doubled haploid lines. A total of 58 doubled haploid lines, and four parental lines i.e. Fatmawati, SGJT-28, SGJT-36, and Way Rarem were used in this study. The experiment used completely randomized design with three replications. Results showed that the characters of the doubled haploid lines vary considerably. Selection of the character i.e. number of productive tillers, number of fi lled grain per panicle, and percentage of empty grain was more effective to be selected because they were well correlated to weight of grain per hill, possessed high heritability values, and have wide genetic variability. Based on productive tillers number, number of fi lled grains per panicle, fertility, weight of 1,000 grains, and weight of grains per hill, the lines of P3-26, P3-27, P3-28, P4-45, P5-50, P6-103, P6-105, P3-120, P3-134, P3-135, P3-150, P3-158, P3-248, P3-249, P6-271, P6-272, P6-274, P6-276, and P6-295 were potential for further selection for new type of upland rice.

Abstract

Eighteen Indonesian new plant type (NPT) of rice varieties and lines were evaluated in a ratoon system. The results showed that ratooning ability was related to the vegetative growth prior to harvest, which gave high ability ratoon growth. New plant type varieties and several lines of rice had better vegetative growth and produced higher ratoon than other genotypes. Ratoons started to develop 2-7 days after harvest, with an average number of leaf 2-4 per tiller. Number of productive tillers of ratoon ranged from 6.0 to 30.0 per hill, with number of grain per panicle ranged from 38.0 to 228.2, and grain weight per hill of ratoon 10.4 to 31.2 g, dependent on genotypes. Maturity of ratoon was also dependent on genotypes. On average, maturity was 68 days after harvest of the main crop. Grouping of ratooning ability based on hierarchical cluster analysis resulted in three groups, namely nine genotypes had high potential, fi ve genotypes had medium potential, and four genotypes had low potential. This study indicated that ratoon is potential to increase rice planting index in Indonesia. The genotypes with high ratoon ability need to be evaluated for agronomic performance in the fi eld.

Abstract

Bacterial leaf blight, the disease caused by Xanthomonas oryzae pv. oryzae (Xoo), a seedborne pathogen, has been known to reduce rice yield by 50%. In this study, two consecutive experiments were conducted in order to investigate the effect of various biological seed treatments applied on rice seeds artifi cially infected by Xoo on seed quality and seedling growth. Laboratory experiment was arranged in a completely randomized design while greenhouse experiment was arranged in a completely randomized block design. In both experiments, 12 seed treatments were applied: un-infected seeds (negative control) without seed treatment, Xoo infected seeds (positive control) without seed treatment, infected seeds soaked in bactericide Agrept 0.2%, infected seeds soaked in biological agent suspension isolate A6, infected seeds soaked in A54 isolate, infected seeds soaked in 5/B isolate, infected seeds soaked in 11/C isolate, infected seeds matriconditioned + A6 isolate, infected seeds matriconditioned + A54 isolate, infected seeds matriconditioned + 5/B isolate, and infected seeds matriconditioned + 11/C isolate. Soaking seeds either in Agrept 0.2% or in biological agent suspension was conducted for 30 h. Matriconditioning was conducted using ratio of seeds to carrier (burned rice hull 32 mesh) to biological agent suspension or bactericide solution of 1.0 (g) :0.8 (g): 1.2 (mL) for 30 h in air-conditioned room ca. 25 oC. Results of experiments showed that all biological seed treatments could suppress Xoo in rice seeds. Matriconditioning plus biological agent (isolate A6), biopriming with isolate A6 or isolate A54 were the best seed treatments to improve seed viability and vigor. In greenhouse experiment, matriconditioning plus isolate A54 was the best seed treatment to increase seedling growth.Keywords: biopriming, matriconditioning, rhizobacteria, seed health, viability
