Abstract

Extending the planting area to a less-fertile soil, such as Ultisols, become inevitable choice to increase the national chili pepper production in Indonesia as this types of soil is the largest part of dry land of Indonesia, about 29.7% or around 51 million ha.  However, efforts to increase its productivity by providing sufficient fertilizers application is most frequently inefficient because in the conventional fertilizer applications, broadcasted fertilizer on the soil bed, are not readily available for the plant as their solubility is limited under the plastic mulch and still in the form of granular until the end of planting season.  Fertigation, therefore, maybe the answer for this problem.  The objective of this study was to determine the best NPK fertigation method on four chili pepper hybrids.  The experiment was conducted in a randomized complete block design with three replication, and the treatments were arranged in a split plot design.  As the main plots were NPK fertigation intensity, i.e. 100%, 75%, 50%, 25% and 0% fertigation with the remnant fertilizers were circularly broadcasted surrounding the plant.  As the subplots were chili pepper hybrids, i.e. ‘Maxima’, H39, H14, and ‘UNIB CHR17’.  The results showed that there was no interaction effect of fertigation intensity indicated that all hybrid genotypes showed similar pattern of responses.  The H39 hybrid had better vegetative growth compared to other hybrids in term of plant height, dichotomous height, stem diameter, number of branches, plant fresh-weight.  Whereas the hybrid cultivar ‘Maxima’ showed the highest yield followed by H14 and cultivar ‘UNIB CHR17’.  The 100% fertigation was the best method of NPK fertilizer application for chili pepper in Ultisols.keywowrd: fertigation, chili pepper, fertilizer application, acidic soil

Abstract

Superior hybrid and CMV tolerant cultivar development requires a pair of high heterobeltiosis parents and both of which are CMV tolerant.  Gene introgression has to be accomplished if the tolerance does not exist in the parents. This research was objected to employ DNA markers and morphological traits on identifying the most resemble BC3 CMV tolerant individuals to their recurrent parents to shortcut the backcrossing cycle. This research used fifteen BC3 populations generated from crosses of hybrid parents PBC1354 and PBC378 with tolerant parents of C1024, C1042 and C1043.  The BC3 populations were previously selected for their CMV tolerance and were characterized by RAPD technique and morphological traits. Selection by means of both RAPD marker and morphological traits identified BC3 individuals 99.9% resemble to their recurrent parent. Genotypes B3A24-20, B3A29-13, B3A29-22, B3B12-13, B3B37-9, B3B12-25, B3C16-5, B3C16-16, B3C34-18 99.9% were similar to PBC378, and  B3D11-8, B3D11-17, B3D38-5, B3E12-17, B3E20-22, B3E31-19  were 99.9% similar to PBC1354.   Those genotypes were both similar to their recurrent parent and tolerance to CMV. The employed strategy shortcut CMV tolerance genes introgression through a backcross breeding.

Abstract

Bengkulu province area elevating from 0 m to over 1000 m above sea level possesses high rice germplasm diversity. To obtain salinity controlling gene(s) from those germplasm, it is required to determine a suitableprotocol. This research was objected to determine NaCl concentration to select Bengkulu rice landraces. The standard most salinity tolerant genotype used in this research was ’Kuning’, a local variety usually grown on tidal area of Seluma Regency for generations. The growing media was Yoshida nutrient culture supplemented with a series of NaCl concentration of 0, 2000, 4000, 6000, 8000 or 10000 ppm. Observation was done every 2 days to find out the response pattern of rice seedling growth on different NaCl concentration. NaCl stress level was determined at 90% seedling dead (LC90) at the eighth day. The results showed that the increase of plantheight was deceased at concentration of 6000 ppm. Based on the mathematical equation generated from the percent mortality data distribution, the LC90 was at 3910 ppm NaCl concentration.

Abstract

Bengkulu Province has many local rice germplasms that have adapted to specific areas. The germplasm has certain character advantages so that it is maintained by farmers. The characteristics of each germplasm need to be identified in order to improve the properties of the existing germplasm. This study aimed to determine the performance, to estimate the value of genetic parameters, and to determine the genetic relationship of local rice genotypes collected from four districts in Bengkulu Province. The results showed that the ‘Kuning Sulaowangi’ genotype was the earliest in maturity had the highest number of tillers amongst genotypes. Genotypes which have significantly the highest average component yields were ‘Kunig Air Dingin’ and ‘Impera’.  Traits that have a high heritability estimated value were weight of 100 grains (91.046%) and grain weight per panicle (80.252%). The weight of 100 grains also has the highest genetic variability value. Thus increasing local rice production is possible. Based on the results of the analysis with the similarity coefficient of 55%, the local rice genotypes could be grouped into two groups.  Group I consisted of 9 genotypes namely ‘Kuning Pendek’, ‘Humbur’, ‘Cantik’, ‘Pandak Kelabu’, ‘Cisadane Putih’, ‘Kuning Sulaowangi’, ‘China Abang’, ‘China Putih’ and ‘Impera’. Other genotypes were in Group II.  Trait improvement can be done through hybridization between individuals of different groups. To develope early in maturity and high-yielding varieties can be done through hybridization of the ‘Kunig Sulaowangi’ and ‘Kunig Air Dingin’

Abstract

Tolerance cultivar is a best control measure to reduce losses due to virus attack in the field.  Study on growth and yield of new cultivars compared to the commercial ones is an important step in cultivar development whether they will be accepted by farmers or not. The objective of this research was to study growth and yield of new chili pepper hybrids developed for CMV tolerance in comparison to a commercial and similar fruit size one. Twelve new hybrids and one commercial hybrid cultivar 'Prada', as a control, were evaluated in a completely randomized design with 3 replications. In the greenhouse experiment, H23 and H20 showed better vegetative growth compared to other hybrids and control. Hybrid H17 showed the highest yield followed by H5, H4 and H6.  Keywords.  growth, yield, chili pepper hybrids, CMV tolerance
