Abstract

Banana accessions introduced from INIBAP Transit Center (ITC) have been studied their diversity revealed on phenotypic and RAPD markers. Both of them showed different clustering pattern and not fit to genomic composition. In order to know fitness level of clustering pattern both of them, comparison analysis have done to their similarity coefficient matrix, and followed by partial correlation analysis among phenotypic traits, and genomic composition. The comparison analysis resulting very poor correlation (r = 0.491). Partially correlation analysis among traits, DNA profile, and Musa genomic composition at 95-99% confidence revealed only OPA-18 line 2 related to accessions possessed pure “Aâ€Â genome, and they were together associated to green color of petiole margins. OPD-10 line 3, significantly, associated to accessions with genome dominated “Bâ€Â, but there was no correlation between both of them to any characters. These results suggested that some primers and characters may specifically associated with certain. Key words: Comparison analysis, Correlation analysis, Introduction bananas, Musa

Abstract

A field research was conducted to study morpho-ecotype and proximate aspects of  Banda nutmeg (Myristica fragrans Houtt.) in three ecotypes: Banda Islands, Ambon Island, and  Ceram Island in Maluku.  The objectives of the study were to characterize morpho-ecotype of the Banda nutmeg, to investigate the trees productivity across three ecotypes, and to identify the proximate characteristics of the fruit.  Ten productive nutmeg sample trees aged ranging 25 to 50 years were chosen for observations.  In morphological observation, 21 items were described based on IBPGR procedure, and then subjected to UPGMA cluster analysis.  The proximates of nutmeg flesh including edible portion (EP), water content, protein content, fat content, and pectin content were analyzed by AOAC procedure.  Morphological and proximate data were analyzed using SAS. Results show that Moluccas ecotypes characterized by hill and mountain has tectonic mountain physiography and karst soils with a slope of 16 to 40%.  Ambon and Banda ecotypes are mainly composed of volcanic soils, whilst Luhu has sediment.  The climate of Moluccas ecotype is dominated by IIIC type, except Banda Island which has IIB. The morphological traits of the nutmeg are stabile across three ecotypes (similarity index, SI 90%).  Productions of fruit, nutmeg, and mace show no difference between the three sites. They are 137.73, 19.27, and 3.07 kg per tree, respectively. All proximate parameters analyzed are not statistically different, except EP.  EP of Ambon ecotype is statistically different from that of Ceram but it is similar to Banda ecotype.   Key words:  Nutmeg, morpho-ecotype, proximate, ecotype.

Abstract

 To accomplish the study of genetic parameters of chili resistance to P. capsici, thirty cross combinations from six parents’ crosses were made by full diallel method.  The resistance was assessed based on the incidence of disease, following the inoculation of 28 days-old plant of chili.  Inoculation was done by dropping 5 mL of inoculum (105 zoospore mL-1) at the base part of each plant. There was non-allelic interaction and overdominance effect. Chili resistance to P. capsici controlled by   one   positive   gene.  The  parents   contained   more  dominant  gene, with dominance order were IPB-C4, IPB-C10, IPB-C15,  IPB-C9,  IPB-C8,  and  IPB-C2. The prediction of the possible limits of selection if homozygote genes assemble on one individual was 0.676-0.691. Broad-sense and narrow-sense heritability values for the traits were high.    Keywords: chili, diallel analysis, genetic parameter, Phytophthora capsici

Abstract

Agronomic performance and heterosis effect of progeny are important criteria for selection of parental hybrid. Theagronomic performance evaluation of Jatropha progeny which was derived from crossing of some Jatropha accessions hasbeen carried out for those goals. The study was conducted at Agro Techno Park, Indralaya South Sumatra. The crossingcombinations were Pidie x Medan, Curup x Lampung, Pidie x Lampung, Lampung x Pidie, Curup x Medan, Indralaya xPontianak, Medan x Palembang, Curup x Pidie, and Jogya x Komering. Oil production, nitrate reductase enzyme activity,leaf chlorophyll content and relative plant growth rate were evaluated. The result showed that the relative plant growth ratecould be used as early detection parameter for yield potential. Progenies of Pontianak x Indralaya, Palembang x Indralayaand Pidie x Lampung were selected as promising hybrids based on high productivity and heterosis effect.Keywords: Jatropha curcas, heterosis, relative plant growth rate, nitrate reductase activity

Abstract

A complete genetic map, including genetic markers for all regions of all the chromosomes in a genome, serves .as framework,for determining the location of genes responsible for variat!on in plant growth and development. Strategies for mapping both discrete and contino us phenotypes are well - established as are efficIent experlmental approaches which minimize the time and cost of genetic mapping. GenetIc map represents a powerful tool In studying the basIs of variation in plant growth and development, and in testing hypothesis. about possible candidate genes. Moreover, genetic mapping serves as starting point for cldning genes, the function (s) of whIch are known only from mutant phenotypes. Key Words.. Genetic map, Linkage, Genome

Abstract

The objective of this experiment was to determine the effect of triacontanol on cucumber production and viability. A comletely randomized design was used, consisting two factors i.e. concentration and time of application. Concentration consists of 5 levels: 0, 0.01, 0.1, 1.0, and 10.0 mg/l while time of application consists of 3 leveles: 2 weeks after planting (W AP), 4 W AP, and 2 & 4 W AP. Concentration, time of application and interaction of the two factors were not significant on vegetative and reproductive variables but were significant on seed weight index, and seed variability. Concentration of O.O1 mg/l and application of 4 WAP gave the best effect on seed viability. (p.11)   Key words: Triacontanol, Seed, Cucumber
