Abstract

Propagating elite oil palm (Elaeis guineensis Jacq.) planting material through in vitro culture techniques requires more time and advanced technique. Early detection of culture stability would facilitate the process of culture selection and maintenance. This research aimed to analyze the DNA fingerprinting of explants and their calli. Calli consisted of embryogenic and non-embryonic calli, which had been subcultured three times. DNA of explants and calli isolated with DNeasy® Plant mini kit (Qiagen) and Genomic DNA Mini Kit (Plant) (Geneaid). DNA was amplified by SSR-PCR using 16 SSR markers, and can be bulked into two groups to save analysis cost.The result showed that 16 markers produced electropherograms that were identical between the explant and calli. Relatedness coefficient indicated that both compared explant and calli were genetically identical (r = 1). The markers used were quite informative with an average PIC number = 0.48 and can be used for DNA fingerprinting analysis of oil palm in vitro culture.

Abstract

Meristem Culture Method for Virus Elimination from Shallot Bulb Shallot farmers in Indonesia have commonly grown bulbs from the previous planting season as seed sources for the next season. This may cause the accumulation of viruses in bulbs which in turn lowering plant productivity. A research was conducted to optimize the meristem culture method combined with thermotherapy (30 ºC) to produce virus-free shallot bulbs. Shallot bulbs of cv. Bima Curut that had been confirmed infected by Potyvirus and Carlavirus were used as explant sources. Bulb sterilization was carried out using bactericides, fungicides, and sodium hypochlorite. Meristem shoots of 0.6 to 0.7 mm in size were isolated from bulbs and plant successively in the shoot, root, and bulb induction medium to form mini bulbs. The mini bulbs were then planted in the screen house for 2 to 2.5 months until micro bulbs were formed. Virus detection by reverse transcription-polymerase chain reaction method confirmed that plantlets at the multiplication stage and plants in the screen house were free of Potyvirus and Carlavirus infestations. This study showed that the meristem culture method combined with thermotherapy is a potential approach for producing virus-free shallot bulbs.

Abstract

Garlic (Allium sativum L.) is used as a medicinal plant or seasoning, but its national production can only meet people's needs by 6.4%, and 95% is imported from China. The development rate of new garlic varieties is relatively slow because garlic is generally propagated vegetatively through cloves; therefore, its diversity has become relatively narrow. Character and diversity can be improved by inducing mutations using gamma-ray irradiation. Experiments on garlic subjected to gamma-ray irradiation have shown physiological changes in the putative 3rd (MV3) mutant offspring. The experiment's 4th mutant progeny (MV4) was re-planted and compared with other local genotypes. The aim was to perform clustering based on the yielding characteristics and the intensity of the anthocyanin content. The experiment used a single-plant design with 21 experimental units, namely 16 MV4 genotypes and 5 control genotypes. The analysis of variance showed that the MV4 Lumbu Kuning 1 Gy and Ciwidey 2 Gy genotypes had better tuber weight and diameter than the other genotypes, including the control genotypes. Cluster analysis clustered garlic genotypes into five groups at a cophenetic distance 0.4. Principal component analysis (PCA) also divided the garlic genotypes into four quadrants. Genotypes in quadrant 2 had anthocyanin content intensities superior to those of other genotypes.

Abstract

“Tawangmangu Baru” garlic variety is known to have low productivity. The variety is still highly demanded due to its strong flavour and aroma; however, its production has not yet been able to fulfill the local needs of Central Java due to the small size and limited production area. This study aimed to determine the effect of concentration and time duration of colchicine treatment towards increasing the ploidy level of “Tawangmangu Baru” garlic variety for genetic variability. The experimental design used in this study was a complete randomized design with two factorials and 12 combinations. The first factor was concentration of colchicine, i.e. 0.00, 0.02, 0.04, 0.06, 0.08 and 0.10%, and the second factor was the immersion time, i.e. 24 and 48 hours. The result indicated that, 4.72% callus induction was obtained in BDS + 0.4 mg.L-1 2,4-D + 2.0 mg.L-1 kinetin; and 4.0% callus proliferation were obtained in both BDS + 1.5 mg.L-1 2,4-D + 1.0 mg.L-1 kinetin and MS +1.5 mg.L-1 2,4-D and 1.0 mg.L-1 kinetin. The untreated plantlets showed higher mortality rate compared to the explants with 48 hours colchicine treatment. Higher number of shoots were recorded in 0.1% colchicine at 48 hours and lower shoots in 24 hours, whereas 0.1% colchicine at 24 and 48 hours showed the highest ploidy level of total nuclear DNA analyzed by flow cytometry. The genetic diversity of the “Tawangmangu Baru” garlic was successfully enhanced by colchicine and immersion treatment. Mutant lines with tetraploid and mixoploid plants were obtained. The putative lines obtained at 0.1% colchicine treatment were subcultured to produce new mutants before testing the phenotype. The application of colchicine at 24 and 48 hours treatment improved the genetic potential of “Tawangmangu Baru” garlic variety in vitro. The application of colchicine increased the ploidy level and an increase in ploidy is expected to make the bulb size larger. Larger tuber size will increase the tuber weight, and also the overall garlic productivity and production in the future.
