Parametric Stability Analysis for Yield of Chili Pepper (Capsicum Annuum L.)

The objective of this study was to identify the stability of seven hybrid chili pepper genotypes that have been developed at Genetics and Plant Breeding Laboratory, Department of Agronomy and Horticulture IPB. The study used eight yield stability analyses and Additive Main Effect Multiplicative Interaction (AMMI) methods. The design was randomized complete block design with three replications as blocks using the genotypes of IPB CH1, IPB CH2, IPB CH3, IPB CH5, IPB CH25, IPB CH28, IPB CH50, and fi ve commercial varieties, i.e. Adipati, Biola, Gada, Hot Beauty and Imperial. These genotypes were planted at six different locations at Ciherang, Leuwikopo, Tajur, Subang, Rembang and Boyolali. IPB CH28, IPB CH25, IPB CH1 and IPB CH2 were more stable cultivars than IPB CH3, IPB CH5, IPB CH50, Adipati and Biola, which had 10, 9, 8, and 6 out of all 10 stability statistics used, respectively. IPB CH28 and IPB CH25 being the most stable cultivars. IPB CH3 was the best genotype compared to the checks based on pair wise GxE interaction test. Based on post predictive success, the AMMI2 model was able to explain 85.51% of the interaction-infl uenced variation. The stable genotypes in six locations were IPB CH1, IPB CH2, IPB CH25, IPB CH28, and IPB CH50. IPB CH3 genotype was locally adapted for Subang

Evaluasi Daya Hasil Cabai Hibrida dan Daya Adaptasinya di Empat Lokasi dalam Dua Tahun

The aim of the experiment was to study the performance of yield components of eight pepper hybrids and their adaptation at four locations in two years (2008 and 2009). The experimental design used was Randomized Complete Block Design (RCBD), three replications as a block was nested in the location. Plant materials were eight hybrids (IPB CH1, IPB CH2, IPB CH3, IPB CH25, and four commercial hybrids were Adipati, Biola, Gada, and Hot Beauty). The IPB CH3 hybrid produced higher fruit width, fruit length, fruit weight, fruit flesh density and yield per plant compared to commercial hybrids. Days to flowering and days to harvesting of IPB CH3 was earlier than that of Hot Beauty. The performance of yield characters in Boyolali, Rembang and Subang was better than that in Bogor. The IPB CH3 hybrid was specifically adapted to Subang and Rembang, while IPB CH1, IPB CH2, IPB CH25 were suitable for Boyolali

Perubahan Sifat-sifat Fisik dan Mekanik Kayu Kemiri (Aleurites Moluccanus (L.) Willd.) Setelah Perlakuan Pemanasan dengan Minyak [Changes Of Physical And Mechanical Properties Of Candlenut Wood (Aleurites Moluccanus (L.) Willd.) After Oil-heat Treatment]

Candlenut wood is one of low quality wood species in term of strength and durability class of V-IV, so its utilization is limited. Efforts to improve physical and mechanical properties of wood are required. One way is using wood modification technology by oil-heat treatment. This research aim was to analyze the changes in physical and mechanical properties of candlenut wood after heating with oil. The stages of this research were sample pre-treatment, heating treatment and wood testing. Samples were pre-treated by heating gradually at 60°C and 90°C for 24 hours to avoid crack during treatment. The heat treatment was applied at several variation of temperatures, namely (160, 180, and 200)°C for 1 and 2 hours, respectively. Properties of wood were tested according to modified ASTM D143-94 standard. The Completely Randomized Design was used to determine effect of heat temperature and time on the wood properties. The results showed that heating with oil on candlenut wood gave a positive response, as evidenced by an increase in physical and mechanical properties of wood. Oil-heat treatment could be an effective method for improve properties of wood. The increases of specific gravity, MOE and MOR were ranged from (16.49 to 26.62)%, (1.25 to 13.61)%, and (4.37 to 10.15)%, respectively. The use of 160°C increased properties of wood with relatively higher compared to other temperatures in 1 hour. Longer heating times tend to reduce properties of wood

Wood Quality of Clones Teak with Different Planting Distance

Many researchs have been done focusing on the wood quality of teak (Tectona grandis L.f.) especially at the various age level and different locations. This research analyzed different planting distance : (3 x 3) m2 and (2 x 6) m2 from 2 clones; Cepu and Madiun cloned. Oven-dried density, fiber dimension, microfibril angle and modulus of elasticity were determined to asses the wood quality. The results showed that the wood quality of teak from spacing (3 x 3) m2 were better than (2 x 6) m2, although diameter and growth rate were higher in spacing (2 x 6) m2. However, there were not diffrences of wood quality for both clones
