Abstract

The objective of this study was to  estimate the  heterosis and heterobeltiosis of thirty chili hybrids, the general combining ability (GCA), and the specific combining ability (SCA) of six chili (Capsicum annuum L.)   inbred lines. The experiment was conducted from October 2005 to March 2006 at IPB Experiment Field, Cikabayan, Darmaga. Randomized Complete Blocked Design was used with three replications.  All characters were significantly different for heterosis, heterobeltiosis, general and specific combining ability. Significant  differences were noted in reciprocal effect for fruit weight, and yield per plant. Hybrid IPB C-2 x IPC C-3 and IPB C-3 x IPB C-1 had positive heterosis and heterobeltiosis values for all variables observed. IPB C-2 showed the highest GCA for yield per plant and fruit length, IPB C-3 and IPB C-7 showed high GCA for yield per plant, fruit length, fruit width, and fruit weight. Crosses having high SCA for all variables observed were IPB C-1 x IPB C-3 and IPB C-2 x IPB C-3. Cross combination of IPB C-2 x IPB C-3 was the best hybrid.   Key words: chili, heterosis, heterobeltiosis, combining ability, full diallel

Abstract

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.

Abstract

Anthracnose is one of the most destructive disease of pepper in Indonesia. Colletotrichum gloeosporioides and C. acutatum have been reported to be predominant species in pepper fields of Asian countries including Indonesia. Inheritance of resistance to anthracnose caused by C. acutatum was studied in Capsicum annuum populations derived from a cross between resistant line 'C-15' and  susceptible line 'C-2'. Twenty green pepper fruits from each plant were inoculated with PYK 04 isolate.  This experiment showed that there was no maternal effect based on t-test of F1 and F1R.  Segregation of resistance and susceptibility in the F2 fitted a normal distrubution, indicated that resistance was controlled by polygenic genes. Eight effective factors were responsible for anthracnose resistance. The degree of dominance was partially recessive. Gene effects for resistance to anthracnose were additive and dominance. Additive variance was larger than dominance variance. Broad-sense heritability values were high but narrow-sense heritability values were medium. Selection for resistance to C. acutatum on pepper breeding programme should be conducted on later generation.   Key words :  Inheritance, anthracnose, resistance, pepper, Colletotrichum acutatum

Abstract

The aim of this research was to evaluate growth and yield in response to aluminum (Al) stress in several genotypes of chilli (Capsicum annuum L.).  The research was  conducted in University Farm of IPB, Cikabayan, Bogor from February to August 2006.  Ultisol soils from Gajrug (Lebak, Banten) in polybag with pH 4.2, Al-dd 30.08 me/ 100 g and Al-saturated 83.81% was used in this experiment.  Eight genotypes of chilli (4 tolerant and 4sensitive) were tested on two different conditions, in media without Al-stress condition (Al-saturated 0.77%) and wich Al-stress (Al-saturated 60.85%).  Characters observed were plant height, shoot dry-weight, total number of fruits per plant, number of fruit harvested per plant, fruit dimension (length and diameter), fruit weight harvested per plant, and weight of each fruit.  The results showed that there were differences of response to Al-stress among genotypes on the study.  PBC 619 and Jatilaba were selected as tolerant genotypes, while Cilibangi 3 and Helm were sensitive.  This evaluation of agronomic characters for tolerant and sensitive to Al-stress appeared very consistent with root bioassay results.  Based on this result, the root bioassay method can be used to select chili genotypes for Al-stress tolerance.   Key words:  Growth and yield evaluation,  aluminum stress, Capsicum annuum, ultisol soil.

Abstract

This study was conducted to determine the relative importance of general (GCA) and specific (SCA) combining ability and heterosis effects on resistance to C. gloeosporioides in selected papaya genotypes. A half diallel mating scheme of five genotypes of papaya were evaluated in the field. The combining ability analysis revealed that both the additive and nonadditive gene effects were present.  Crosses between the resistance and susceptible genotypes showed intermediate disease reaction to papaya anthracnose disease (PAD) suggesting a polygenic system of resistance to the disease. Highly resistance heterosis of 51.51% at Tajur and 48.71% at Gunung Geulis were expressed in crosses between IPB5 x PB000174.   Key words: Papaya, anthracnose, GCA, SCA, heterosis

Abstract

The aim of this research was to test the utilization of arbuscular mycorrhizal fungus (AMF) to improve adaptation ability of chili to aluminum (Al) stress based on growth and yield response in four genotypes of chili (Capsicum annuum L.).  The research was carried out at University Farm of IPB in Cikabayan from September 2006 to Maret 2007.  The media was Ultisol from Gajrug (Lebak, Banten) in polybag.  Four genotypes of chili, PBC 619 and Jatilaba (Al tolerant genotypes), and Cilibangi 3 and Helm (Al sensitive genotypes) were treated with and without inoculation of Gigaspora margarita, and planted further in media without Al stress (Al saturation 0.77%) and Al stress (Al saturation 60.85%).  Variables observed were degree of AMF infection, root length, plant height, shoot dry weight, number of harvested fruits, fruit length, fruit weight and weight of harvested fruits.  The results showed that inoculation of G. margarita effectively decreased negative influence of Al stress by increasing plant height, shoot dry weight, number of harvested fruit, fruit length, weight per fruit and weight of harvested fruits.  Inoculation of G. margarita to Al sensitive genotypes was more advantageous than to tolerant genotypes.  The Al sensitive genotypes were adapted to Al stress if they were inoculated with G. margarita.  In Al stress condition, inoculation of G. margarita to Al sensitive genotypes increased weight of harvested fruits up to 94.49% in Cilibangi 3 and 80.37% in Helm.   Key words: Adaptation, aluminum stress, arbuscular mycorrhizal fungus, Capsicum annuum L., Ultisol

Abstract

Papaya plants are hermaphrodite, pistillate, or staminate. Sex inheritance in papaya is determined by a single gene locus with three alleles of M which is dominant for maleness, MH for hermaphrodites and m which is recessive for femaleness. Only fruits from hermaphrodite plants are marketed since they have the necessary commercial characteristics, i.e., they are pear-shaped and have thicker flesh and a smaller internal cavity. Increased papaya yield has been limited mainly by the ratio of female to hermaphrodite (1: 2) plants normally occurring in orchards. This ratio causes great losses to papaya producers. Identification of seedlings sex during nursery stage is of prime iportance. In order to obtain simple DNA markers to identify sex expression in papaya, five SCAR markers of 20-21 primers were utilized. Examination of these markers into 24 genotypes of papaya from 12 populations of different genetic background revealed that pair of primer PKBT-5 had successfully differentiated male and hermaphrodite plants from female plants. Hence, PKBT-5 pair of primer can be utilized as DNA marker for sex expression character identification in papayas.   Key words: Papaya, sex expression, SCAR marker

Abstract

The genus of Carica comprises 21 species, among them three species have been domesticated and cultivated. They are Carica papaya, Carica candamarcencis and Carica monoica. In Indonesia, two species have been cultivated viz. Carica papaya and Carica candamarcencis. In this study, four accessions of Carica papaya species and one accession of Carica candamarcencis species were analyzed using RAPD technique. We successfully amplified a total I of 40 fragments from these DNA genome by using 6 random primers with GC bases content:::: 60% of each primer. The number of fragments of each primer ranged from 5 to 8 averaged 6.7 fragments per primer. Out of total fragments, 90% showed as polymorphic ranged from 5 to 8 on average 6 fragments per primer. A dendogram based on the UPGMA- link method using Nei and Li similarity and Principal Component Analysis (PCA) plot separated the accessions into two main groups, the Carica papaya species on the one side and the Carica candamarcencis species on the other side. The result demonstrated that RAPD analysis was able to reveal genetic difference between Carica papaya and Carica candamarcencis species, as well as genetic diversity in Carica papaya species.
