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

This research was aimed at studying the effectiveness of  mycorrhiza, inorganic and organic fertilizer (fish and shrimp waste) on growth, yield and quality of Aloe in peat soil. The study was conducted on peat area, North Pontianak, West Kalimantan. Mycorrhizal application levels (without mycorrhiza, Mycofer and mycorrhizal from pineapple's rhizosphere) were as main-plot. The inorganic fertilizer (composition of N:P:K:Mg) rates (without inorganic fertilizer;  5 : 4 : 7.5 : 2.5 g/plant;  10 : 8 : 15 : 5 g/plant; and  20 : 16 : 30 : 10 g/plant) were as sub-plot.  Organic fertilizers: (fish; shrimp; fermented fish; and fermented shrimp wastes) were as sub-sub plot. The observed variables were: leaf width, leaf length, leaf fresh weight, plant dry weight, and nutrient uptake (N, P, K, Mg). The results showed that mycorrhizal application improved growth performance and increased N, P, Mg uptake. The best plant growth performance was achieved by N : P: K : Mg  =10 : 8 : 15 : 5 g/plant and fermented shrimp waste treatments.  The highest  N, P, K, Mg nutrients uptake was achieved by application of fermented organic  fertilizer.  Combination of mycorrhiza from pineapple's  rhizosphere with fermented fish and shrimp waste resulted in higher amino acids content compared to standard cultivation of  Aloe vera Center in Pontianak.   Key words:  Aloe vera, arbuscular mycorrhiza, inorganic fertilizer, organic fertilizer

Abstract

Since physic nut (Jatropha curcas L.) is heterozygous, sexual propagation results in great genotypic and phenotypic variability. Development of efficient techniques for asexual propagation would benefit the nursery industry as this would lead to selection and production of particular clones with desirable characteristics. Therefore, two following studies were conducted from September until December 2007.  The objective was develop a protocol for vegetative propagation of physic nut by stem cutting in different size of cutting. The first experiment was dealt with stem cutting length (20 cm, 25 cm, and 30 cm) at the same size of diameter (2.5-3.0 cm), and the second experiment was dealt with diameter of stem cutting (3 cm, 2.5-2.9 cm, 2.0-2.4 cm, and 1.5-1.9 cm) at the same size of length (30 cm). Each of experiment was designed in Completely Randomized Design with three replications. Each experimental unit consisted of 25 seedlings. The result showed that cutting growth varied depending on length and diameter of stem cutting. However, better seedling growth and better survival of young plant of physic nut can be obtained from stem cutting with 20-30 cm in length and stem cutting with 2.0-2.9 cm in diameter.   Key words: cutting diameter, cutting length, Jatropha, survival, transplanting

Abstract

Hybrid rice has been proven to be the key factor to increase food supply in highly populated countries such as China and India. The success has encouraged the government of Indonesia to intensify research and development on hybrid rice using cytoplasmic-genetic male sterility system. The use of good male sterile line is a prerequisite for commercial seed production of hybrid rice.  The objective of this research was to evaluate several F1 plants to develop completely sterile cytoplasmic male sterile line (CMS) with good agronomic characters.  This research was conducted at screen house of Bogor Agricultural University during dry season (DS) of 2007.  Fourty eight F1s, derived from testcross between cytoplasmic male sterile sources with doubled-haploid (DH) maintainer lines, were evaluated in randomized complete design using three replications.  Observation was done on pollen sterility, panicle and stigma exsertion, plant height, and tillering ability.  The results showed 14 F1s were completely sterile (100 % pollen sterility).  They were A-2/H36-3-Ma, A-1/H36-3-Mb, A-2/H36-3-Mb, A-3/H36-3-Mb, A-1/H36-4-M, A-2/B1-1-Mb, A-3/B1-1-Mb, A-1/B1-2-Pa, A-2/B1-2-Pb, A-3/B2-1-M, A-1/B2-4-Pb, A-3/B4-1-Da, A-1/B4-1-Dc, and A-3/B4-1-Dc.  They also had early flowering date, averaged from 66 - 90 days after planting (DAP).  There were other 14 F1s with stigma exsertion more than 70 % and good panicle exsertion, i.e.  A-2/H36-3-Mb, A-1/H36-3-Mc, A-2/H36-3-Mc, A-1/H36-4-M, A-2/B1-2-Pa, A-2/B1-2-Pb, A-3/B2-1-Db, A-1/B2-1-Dc, A-1/B2-1-M, A-1/B2-4-Pb, A-3/B2-4-Pb, A-2/B4-1-Da, A-1/B4-1-Dc and A-3/B4-1-Dc.  However, only five F1s had all desirable characteristics as male sterile line candidates, such as 100% pollen sterility, good panicle exsertion, high stigma exsertion, semi-dwarf in plant height and good tillering ability.  They were A-1/H36-4-M, A-2/B1-2-Pb, A-1/B2-4-Pb, A-1/B4-1-Dc, A-3/B4-1-Dc.   Key words:  Doubled-haploid maintainer lines, CMS, pollen sterility, hybrid rice

Abstract

Low soil fertility is the most important factor constraining corn (Zea mays L.) yield in marginal land due to soil acidity.  Corn cultivars with high nutrient efficiency and tolerance to soil acidity offer an alternative to solve the problem.  A Complex population had been formed by natural crossing among six cultivars/line expected to carry the nutrient efficiency character; Sukmaraga, Lamuru, Srikandi Kuning, Bisma, Bayu, and Toray and used as a genetic material in this study.  The objectives were (i) to evaluate the agronomic performance of complex population in marginal land under limited nutrient supply, (ii) to select the superior entries in each population for nutrient efficiency, and (iii) to identify the characters relate to yield (nutrient efficiency).  The selection of nutrient efficiency was based on the ear dry weight produced per plant (yield).  The experiment was conducted in marginal land at Agro Techno Park, Indralaya, South Sumatra in January to April 2008.  Randomized Complete Block Design with four replications was used.  The treatment was number of entries that grouped into six populations based on a female parent.  Plants were fertilized with Urea, SP-36, and KCl at 30% of standard rate.  Sukmaraga population had the best agronomic performance among six populations evaluated. The superior entries selected were top 10% of the total entries in each population with ear weight more than 150 g. All the characters (ear length and diameter, plant height, leaf chlorophyll, leaf numbers above the ear, and ear leaf area) related to yield (nutrient efficiency) but plant height is the only character measured before anthesis.  The results suggest that Sukmaraga population had use nutrient more efficiently than the other populations and plant height may be used as selection criterion in early screening large numbers of corn entries or lines for nutrient efficiency.        Key words:  Agronomic characters, corn, marginal land, nutrient efficiency

Abstract

The research had an objective to analyse the population of F2 and first selection (S1) generations of the cross between soybean cultivar Slamet and Wase. The ultimate goal of this research is to obtain the elite cultivars of soybean having high yield, big seeds, and tolerant to acid and aluminum stresses. The genetic variance and heritability in the broad sense of all characters observed of F2 population were very high. The seed productivity of F2 population was higher than that of Slamet and Wase cultivars. The size of seeds of F2 population was bigger than that of Slamet and comparable to that of Wase. The heritability in the broad sense of all characters of F2 population was very high because the maximum segregation occurs in F2 and the two parents had a very different genetic back ground. By using 7.5% selection intensity based on productivity, we got selected F2 population having productivity two times than that of Slamet. Seeds of this selected F2 population were bigger than that of F2 population and cultivar Slamet. The S1 population had seed productivity higher than Slamet and Wase cultivars. The heritability in the broad sense of all characters of S1 population was smaller than that of F2 population caused by the selection. The selection by 4.8% intensity resulted the selected S1 population having productivity three times than that of cultivar Slamet and big seeds. The selected S1 population had a phenotype variance of productivity smaller than S1 population. Therefore, the selected S1 population is very potential to be developed as elite soybean cultivars.   Key words: soybean, genetic variance, heritability, selection, F2 population
