Abstract

 The objectives of this study were to compare nonparametric stability measures, and to identify promising high yield and stability of chili pepper (Capsicum annuum L.) genotypes in eight environments. In every environment, a Randomized Complete Block Design was used with three replications. The method of Nassar and Huehn, Kang, Fox, and Thennarasu was used to analyze the stability and high yield. Spearman’s correlation and Principal Component analysis distinguishes the methods based on two different concepts of stability: the static (biological) and dynamic (agronomic) concepts. The top method was found to be the dynamic stability. Meanwhile, the methods of Si1, Si2, Si3, Si6, Npi1, NPi2, NPi3 and NPi4 were found to be the static stability. Based on the ranking frequency stability of the nonparametric method, the genotypes with the highest frequency of static stability ranking were genotypes IPB002003, IPB002046, IPB009019 and Tit Super, whereas IPB009002 and Tombak were categorized as those of dynamic stability. Genotype IPB120005 and IPB019015 were less adaptable in the multiple environments tested. It shows that the genotypes were specific in certain environments. IPB120005 had high yield and specific location in Boyolali in dry season and IPB019015 genotype was specific in Bogor in wet season. Keywords: chili pepper, nonparametric stability, high yield, dynamic stablility

Abstract

This study was conducted to evaluate the effectiveness of plant growth promoting rhizobacteria (PGPR) in protecting chillipepper plant from infection of cucumber mosaic virus (CMV) and chilli veinal mottle virus (ChiVMV). Seven isolates of PGPR, i.e. BC1, BTP2H, BTP3G, BTP3O BTP1, BTP2D, and T1F were applied as seed treatment and soil drench. Plants height, number of branch, and fruits weight were measured every one and ten weeks after virus inoculation. Virus concentration in plants and disease incidence were confirmed by enzyme-linked immunosorbant assay (ELISA). Results showed that inoculation with PGPR improved the seed germination. Eight days after sowing, the percentage of PGPR treated seed germination reached 50-84%; whereas those of untreated seed reached only 18%. In general, PGPR treatment significantly reduced (p < 0.05) the effect of virus infection on plant growth. Two PGPR isolates, i.e. BTP1 and BTP2H, maintained fruit weight of infected plants as good as those of healthy plants. Based on ELISA, PGPR was able to inhibit the disease incidence. The BTP3O and BTP2D isolates even protected the plant from ChiVMV infection. Concentration of salicylic acid and peroxidase were relatively higher on plants treated with PGPR than those without PGPR treatment. This gave an indication that PGPR may act as induction agents for systemic acquired resistance. Therefore, PGPR treatment is a promising strategy to control viral diseases on chillipepper.

Abstract

A research was undergone to study the effect of single and double infection of Cucumber Mosaic Virus (CMV) and Chili Veinal Mottle Virus (ChiVMV) on the growth and yield of five chilli cultivars, i.e. Prabu, Taro, Jatilaba, Laris, and Keriting Bogor. Mechanical inoculation was conducted to transmit the virus. Infection of the virus was then confirmed with DAS-ELISA. Severe symptom was observed on plant given double infection compared to those given single infection. The rate of plant growth and the amount and weight of fruits were reduced. The type of interaction between CMV and ChiVMV on most chilli cultivar can be considered as interference and additive. Synergism interaction was only observed on cultivar Laris. Based on symptom expression and reduction on yield, it can be concluded that all chilli cultivars used in this study could not hold up the virus infection. Key words: CMV, ChiVMV, interaction, additive, interference, synergism

Abstract

Begomovirus infection was identified from tomato growing areas in West Java (Bogor), Central Java (Boyolali), and D.I. Yogyakarta (Kaliurang). Efforts to reduce the infection among others are planting resistance varieties. This research was undertaken to evaluate 14 tomato genotypes for their response to the infection. Dot blot hybridization using nonradioactive (digoxigenin) DNA probe was employed to determine the presence of begomovirus in inoculated plants. Polymerase chain reaction-amplified product of DNA clone of tobacco leaf curl virus –Indonesia was used as a source of DNA probe. All of tomato genotypes evaluated in this study was infected separately by three strain of begomovirus (GVPSlm, GVABy, GVCBgr). Tomato genotypes Bonanza, Jelita, Safira, Permata, Presto, PSPT 8, PSPT 5B, Apel-Belgia, Karibia, Mitra, PSPT 9, Marta, and PSPT 2, showed susceptible or highly susceptible response to the three strains of begomovirus. Exception to those was shown by cv. Intan which resulted in moderate resistance when inoculated with GVCBgr although it resulted susceptible response with the other two strains. Dot-blot hybridization technique was proved to be a powerful tool to detect begomovirus infection in plants showing symptom as well as symptom-less plants. Accumulation of the virus in those plants was relatively high, except in cv. Bonanza and Apel-Belgia. Dot-blot hybridization technique using DIG-labeled DNA probe was able to detect begomovirus DNA in infected tissue up to 10-2 dilution factor.

Abstract

Sweet corn is a result of recessive mutation which occurs naturally in gene that controls the conversion of sugar into starch in corn seed endosperm. There are 3 main genes that affect corn sweetness, namely sugary gene (su), sugary enhancer gene (se), and shrunken gene (sh2). This study aims to obtain a general combining ability value for the sweet corn lines, which will be the parent in diallel crosses; obtain the information of general combining ability, specific combining ability, and heterosis value for sweet corn lines; and obtain one or more promising single cross hybrids that will be potential for high yield and resistance to downy mildew disease. The study was conducted from April 2009 until November 2011 at the Experimental Field Centre for Cereal Plant Study (BALITSEREAL), Maros, South Sulawesi. The results showed that five genotypes had moderately high yield: Mr4/SC/BC4-3-1B, Mr14/SC/BC4-6-1B, Mr11/SC/BC4-3-1B, Mr14/SC/BC3-8-1B, and Mr12/SC/BC4-6-1B. The attack level of downy mildew that was classified as resistant has 0 to 7% rate. The combination of crosses that produce better productivity than all the varieties are: C × A (Mr11/SC/BC4-2-1B-1 × Mr12/SC/BC4-5-B-1), A × D (Mr12/SC/BC4-5-B-1 × Mr11/SC/BC4-2-1B-1), E × B (Mr12/SC/BC3-3-1B -1 × Mr14/SC/BC4-6-1B-1), and B × D (Mr11/SC/BC4-2-1B-1 × Mr14/SC/BC4-6-1B-1 ). Five hybrids can be continued for the preliminary testing of yields. Twelve candidate varieties do not have yield different than the checked varieties, so it can proceed to a multilocation trials to explore the advantages that can be released as new varieties.

Abstract

Inheritance of resistance trait to ChiVMV was studied in intraspecific capsicum population derived from a cross between two Capsicum annuum line, PBC495 as a resistance line and ICPN12#4 as a susceptible line. The resistance was assessed by diseased index (DI) and score of absorbance value at  405 nm, two weeks after inoculation. Based on t-test of F1 and F1R, it was concluded that there was no maternal effect. Nil symptoms resembling the resistant parent were identified in the progeny F2, BC1P1 (BC1 to the resistant parent) and BC1P2 (BC1 to the susceptible parent) populations. Segregation of resistance (nil DI and lower absorbance value) and susceptibility in the F2 fitted a 3:1 Mendelian ratio, indicating that resistance were controlled by a single dominant nuclear gene. Nil segregation of the trait in the test crosses in BC1P1 and a 1:1 ratio segregation in BC1P2 also confirmed the 3:1 gene segregating model as found in the F2. Heritability values of the trait were medium to high.Key words : inheritance, resistance, ChiVMV, pepper

Abstract

Appearance of a plant is determined by genetic factors, environmental factors and interactions between them. The genetic x environment interactions become an important concern for breeders, in addition to genetic factors. Purpose of this study was to examine the genetic x environment interactions for resistance of pepper to anthracnose. Materials used were 16 hybrids that were planted at three locations. Complete randomized block design (RCBD) was used with three replications. Replicates nested within location. Twenty of hot pepper that has been worn but is still green from each replication was inoculated with C. acutatum, PYK 04 isolate. Disease incidence was observed five days after inoculation. The results showed that the genotype x location interaction was significant different to resistance resistance caused by Colletotrichum acutatum PYK 04 isolate. Pepper genotypes stable in anthracnose resistant character in three selection environments was IPB CH3, IPB CH6, and IPB CH25. The genotypes were suitable for selection environment Ciherang, Leuwikopo and Tajur. Genotype IPB CH50 and IPB CH51 were suitable for selection environment Tajur. Imperial genotypes was suitable for the environment selection Ciherang. IPB CH5 and IPB CH4 CH5 were suitable for Lewikopo environment.Keywords:genetic x environmental interaction, anthracnose, resistance, pepper, Colletotrichum acutatum
