Abstract

Establishment of homozygous lines can be accelerated with anther culture technique that can produce pure lines in one generation. Formation of spontaneous double haploid plants in rice anther culture is very beneficial, because it does not need to be doubled haploid plants as material selection.This study aims to obtain a doubled haploid lines of upland rice is tolerant to drought and blast disease resistance. The main ingredient in this research is anther crosses of rice plants (F1), which consists of local varieties with selected lines of P1 (Sriwijaya x IR-148), P2 (Sriwijaya x IR-7858-1), P3 (Bugis x IR -148), and P4 (Bugis x IR-7858-1), callus induction media (N6), regeneration medium (MS). Anther culture of local varieties of rice indica/indica produced callus induction and plant regeneration are low, resulting in low efficiency of anther culture in providing green plants. The use of donor parents indica/j aponica which is responsive to anther culture into consideration for the material F1 crosses. Anther inoculation needs to be done in several stages so that the opportunity to obtain plantlets in sufficient quantities for material selection will be greater.

Abstract

Bacterial wilt (Ralstonia solanacearum) is the most important tomato diseases which can reduce tomato yield up to 100%. One most prospective control measure is the development of high yielding varieties tolerance to bacterial wilt. Donor parent carrying bacterial wilt controlling gene(s) is required to develop such varieties. The objectives of this study were to screen thirty-seven tomato genotypes for tolerance to R. solanacearum and to obtain RAPD markers of resistance to bacterial wilt. The experiment was arranged without the experimental design. Each tomato genotypes consisting of 5 control uninoculated plants and 10 plants were inoculated with R. solanacearum with a concentration of 106 cfu / ml inoculum of 10 mL per plant. Scoring was done on the severity of disease symptom; and the plants were grouped according to scoring class. Molecular analysis was done by using Bulk Segregant Analysis (BSA). The results showed there were six genotypes considerd very tolerant i.e. genotype Pearl, Opal, Cung, Syu and Kudamati I; tolerant genotypes consisting of five genotypes; medium tolerant groups consisting of eight genotypes; medium sensitives groups consisting of 14 genotypes; and sensitive class consisting of four genotypes, namely Aceh Local Tomatoes I, Tanah Datar Local Tomato, Tomato Meranti I and Tomato Meranti II. Of the 20 primers used only 8 primers showed visible DNA bands, they were E1, E7, E10, H2, H5, H13, H16 and H19. However there no polymorphics bands observed for bacterial wilt tolerance.

Abstract

Pineapple plants are usually propagated vegetatively by utilizing the base of the fruit (ratoone), stem buds (sucker), fruit buds (slip) and crown (crown). Propagation of plants by utilizing parts of the plant is less effective in meeting the needs because the planting material produced is small and requires a long time. An alternative to the propagation of pineapple to increase the amount of planting material is by tissue culture techniques. This study aims to obtain the best types of complex organic compounds and the right concentration for the growth of pineapple shoots in vitro. The research was conducted in June 2017 until October 2017 at the Laboratory of Agronomy at the Faculty of Agriculture, University of Bengkulu. Complete randomized design with 3 replications was used to allocate 9 treatments of complex organic compounds. The basic media used are the composition of Murashige and Skoog (MS). Treatment consists of 1) Coconut water 100 ml / l, 2) Coconut water 150 ml / l, 3) Coconut water 200 ml / l, 4) Banana porridge 100 gl / l, 5) Banana pulp 150 g / l, 6) Banana slurry 200 g / l, 7) Bean sprout extract 100 g / l, 8) Bean sprout extract 150 g / l, 9) Bean sprout extract 200 g / l. The results showed that at 16 weeks after MS media planting the addition of 100 g / l banana pulp was able to produce the highest plant height with an average of 3.45 cm. MS media with the addition of 200 ml coconut water resulted in the highest shoot height of 1.5 cm and followed by MS with the addition of 100 g / l media of banana pulp with an average of 0.9 cm. MS media with the addition of 100 ml / l of coconut water is suitable for the growth of pineapple roots with the average value of the number of roots and the highest length of roots. MS media with the addition of bean sprout extract with various concentrations is not able to stimulate shoot growth and has a growth response that tends to be slow. Keywords: Pineapple, In Vitro, Complex Organic Compounds.

Abstract

Coastal area of Bengkulu Province is home of many heirloom rice varieties and play an important role in contributing rice production in the province. However, as the climate change proceeds, a progressive sea water inundation has increased soil salinity mainly in low-lying areas and jeopardizing the sustainability of rice production in coastal regions.  The use of salt-tolerant varieties, therefore, would be a sensible solution to alleviate the adverse effect of soil salinity in respect of maintaining the crop production in the coastal areas. The objective of this study was to examine the salinity tolerance of 20 heirloom rice varieties collected from a coastal area of Bengkulu Province.  Prior to the screening process, lethal concentration 90 (LC90) was determined by assaying the seedlings of ‘Kuning Tinggi’ in a series of nutrient solution containing a different concentration of NaCl (0, 2000, 4000, 6000, 8000 and 10000 ppm). Using a regression analysis, LC90 was detected at a concentration of 3910 ppm. The screening was performed by exposing the varieties in the nutrient solution culture containing 4000 ppm NaCl and growing them on the tidal swamp. Under nutrient culture evaluation, the symptom of NaCl toxicity was scored and converted to salinity tolerance index. ‘Humbur’, ‘Kuning Tinggi’ and ‘Padang Bakung’ exhibited medium tolerant, while ‘Beram’, ‘Imperata’ and ‘Kuning’ exhibited very sensitive. Further evaluation of the tidal swamp for vegetative and generative performances signified that ‘Humbur’ and ‘Kuning Tinggi’ had medium tolerant to salinity stress

Abstract

[PATH ANALYSIS OF GROWTH CHARACTERS AND YIELD COMPONENTS WITH THE YIELD OF 15 GENOTYPES OF MAIZE HYBRID].  Determination of traits used as the selection criteria are based on the trait(s) that have a close relationship to the yield.  The aims of this research were to measure the closeness of the relationship between morphological (growth and yield component) traits and crop yield, and to determine the trait that directly or indirectly affected on maize yield.  The research was conducted in Rimbo Kedui’s Village, South Seluma Subdistrict, Seluma District, Bengkulu Province on May 2017 to August 2017.  The experimental design used was a Complete Randomized Block Design (CRBD) in a single factor with 3 replications.  The treatments were 15 maize hybrid genotypes, consisting of CT1, CT2, CT3, CT4, CT5, CT6, CT7, CT8, CT9, CT10, CT11, CT12, CT13, CT14, and CT15.  The data were statistically analyzed by analysis of varians (ANOVA) with P(a=5%).  The qualitative data were analyzed descriptively. The result of correlation analysis revealed that the yield of maize hybrids highly correlated to some growth and yield component factors.  High-yielding maize hybrids were supported by higher ear diameter, plant fresh weight, plant dry weight, plant height, the number of seeds per ear.  Plant dry weight became the variable that has the highest direct effect with positive correlation on the yield.  The second highest rank was the number of seeds per ear with also a positive correlation value.  Yield improvement of maize hybrid, therefore, can be obtained by fostering the plant total biomass and/or by multiplying the number of seeds per ear.
