Laboratory and field experiments were carried out to analyze genetic diversity of 22 pepper genotypes (Capsicum spp.) and their resistance to Phytophthora capsici Leonian. Resistance screening was performed in plastic flats 72 cells. Inoculation was done on 28-day old pepper plant soon after watering by pipeting 5 ml of inoculum (105 zoospore/ml) at the base of each plant. P. capsici isolate used in this experiment was TG01, identified as race 3 based on AVRDC differential pepper lines (PI 188478, PBC 602, PBC 137 and Early Calwonder). The evaluation of pepper genotypes characteristic was conducted in the field. Principle Component Analysis, Clustering Analysis and Biplot Analysis were used to analyze genetic diversity based on 37 characters. Result of resistance evaluation showed that two genotypes (C4 and C13) were identified as resistant, 7 genotypes (C2, C3, C5, C8, C10, C15, and C20) as slightly resistant, 6 genotypes (C7, C9, C17, C19, C21 and C27) as slightly susceptible, and 7 genotypes (C1, C11, C18, C28, C48, C64, and C65) as susceptible. Based on genetic diversity analyzed, all genotypes could be divided into 4 clusters. Cluster I consisted of 18 genotypes i.e. C1, C2, C3, C4, C5, C7, C8, C9, C10, C13, C14, C15, C17, C18, C19, C28, C64, and C65. Cluster II consisted of only 1 genotype i.e. C48. Cluster III consisted of 2 genotypes (C20 and C21) which were characterized by the colour of corolla, corolla spot, and filament. Cluster IV consisted of 1 genotype (C27) which was characterized by fruit cross-sectional corrugation. Key words : Capsicum, resistance, Phytophthora capsici, genetic diversity, clustering.

The objective of this research was to study the effect of seed coating using Benomil and curcuma powder on seedborne diseases of antrachnose and seed viability of Capsicum annuum L.. This research was conducted in Laboratory of Plant Mycology and Laboratory of Seed Science and Technology IPB, from June to July 2006. This research consisted of three experiments, i.e.: (1) the effectiveness of seed coating in decreasing infection level of antrachnose fungus in the seed of chilli, (2) the effect of seed coating on seed viability, (3) the effect of seed coating in reducing infection level of antracnose at hypocotyl of chilli. The Experiment 1 and 3 used Randomized Complete Design and the experiment 2 used Randomized Complete Block Design. The result of this research showed that seed coating with Benomil and curcuma powder significantly decreased the infection level of antrachnose fungus on seed and hypocotyl (Benomil 2.5 g/l and curcuma powder 1 g/l). However, seed coating with curcuma 1 g/l had the lowest vigour index, seedling growth rate and seed germination (3%, 2.26%, 23%). Seedcoating with Benomil 2.5 g/l and curcuma powder did not significantly affect the maximum growth potential, seed germination, and vigour index. However, Benomil significantly decreased the seedling growth rate. Key wods : chilli, seed coating, antrachnose, curcuma, benomil, viability

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

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

Selection criteria for developing Phytophthora blight-resistant varieties of pepper had been done in both laboratory and ﬁ eld conditions. Resistance screening were conducted on 28-days-old pepper plants grown in 72-cell ﬂ ats by inoculating 5 mL of inoculum (contain 105 zoospore mL-1) to the base of each plant. Phytophthora capsici isolate used in this experiment was TG01, which then identiﬁ ed as race-3. The evaluation of pepper genotypes characteristics were conducted in ﬁ eld. Eight characters demonstrated a wide genetic variability; those characters were resistance to Phytophthora blight, infection period, dicotomous height, canopy width, fruit weight, fruit length, fruit diameter and production. These characters along with fruit wall thickness, chlorophyll-a, chlorophyll-b, total chlorophyll had high heritability values. Using path analysis infection period, dicotomous height and fruit diameter are recommended to be simultaneously used as selection criteria for developing Phytophthora blight resistant pepper varieties. Keywords : capsicum, Phytophthora capsici, selection criteria, path analysis

A study was conducted to determine Jatropha fruits ripening uniformity on its tree and bunches characteristics. To get more information about its ripening off, the tree characteristics a respiration pattern was determined. The data were collected on ﬁ ve trees for each ten selected accessions (n=50) for fruit ripening uniformity on its trees study and ﬁ fteen bunches for each seven selected accessions (n=105) for fruits bunches ripening uniformity study at two jatropha pilot projects at Sabah state of Malaysia at the end of March 2009 when the trees were exactly one year old. This study conﬁ rmed that heterogeneous ripening occured in all jatropha accessions and within individual jatropha bunches. Respiration tests conﬁ rmed that jatropha is a climacteric fruit. The results showed an upsurge in CO2 production at the end of ripening and at the beginning of senescence. This study has revealed indications of the possibility to harvest jatropha fruit in bunches rather than harvesting individual ripe fruit, which could potentially improve harvest efﬁ ciency by reducing harvesting time and drudgery. Keywords: ripening, respiration rate, post-harvest, climacteric

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.
