Abstract

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.   Keywords: fruit, yield components, genotype x location interaction, Capsicum annuum L.

Abstract

Melastoma malabathricum L. grows well in acid soil with high level of soluble aluminum. One of the important proteins in the detoxifying acid and aluminum stress is a plasma membrane H+  -ATPase protein encoded by PMA gene. The objective of this research was to isolate and clone the cDNA fragment of MmPMA encoding plasma membrane H+ -ATPase from M. malabathricum L. By reverse transcription, total cDNA had been synthesized from the total RNA as template. The fragment of MmPMA  cDNA  had been successfully isolated by PCR by using total cDNA  as  template and PMA primer designed from conserved region for corresponding gene. This fragment had been successfully inserted into pGEM-T Easy and the recombinant plasmid was successfully introduced into E. coli DH5". Nucleotide sequence analysis showed that the length of MmPMA fragment is 806 bp encoding 268 amino acids. Local alignment analysis based on nucleotide of mRNA showed that MmPMA fragment was 81% identical to part of PMA of Sesbania rostrata, Juglans regia, and Prunus persica. Based on deduced amino acid sequence, MmPMA was 94% identical to part of PMA of Juglans regia; 93% to PMA of S. rostrata, and Arabidopsis thaliana. MmPMA fragment has phosphorylation intermediate domain (DKTGT) and ATP binding domain (KGAP, DPPR, MITGD, and GDGVN).   Keywords: isolation, Melastoma malabathricum L., MmPMA fragment, sequencing

Abstract

The successful of gene transformation on crop plants depends on the ability of explant to develop somatic embryos. The effect of medium composition on induction and proliferation of embryonic callus was analyzed on several soybean genotypes, including low irradiance (LI) tolerant genotype (Ceneng, Pangrango C6-30-10 and C6-76-10) and two LI sensitive genotypes (Godeg and Slamet). Immature cotyledons (14 DAA) were cultured in induction medium including MSIA (MS, vitamin B5, 30% sucrose, 0.2% gelrite, 10 mg L-1 2,4-D and 10 mg L-1 NAA) and MSIB (MS, vitamin B5, 30% sucrose, 0.2% gelrite, and 40 mg L-1 2,4-D). Embryonic calli was subcultered one month after initiation onto proliferation medium including MSIIA (MS, vit. B5, 30% sucrose, 0.2% gelrite, 5 mg L-1 2,4-D and 5 mg L-1 NAA) and MSIIB (MS, vitamin B5, 30% sucrose, 0.2% gelrite, and 20 mg L-1 2,4-D). The result showed that percentage of callused explant was 76-94% and the highest initiation obtained on Pangrango genotypes. The average of calli diameter at 1 month after initiation was 0.5-1.2 cm. Calli which was obtained on MSIA medium showed yellow, tranparent, and friable, whereas calli was obtained on MSIB medium showed yellow-brown, transparent, and friable. Increasing calli diameter and structure were obtained on proliferation medium. The combination of 2,4-D and NAA on MSIA and MSIIA both are induction and proliferation medium respectively were better than MSIB and MSIIB which were contain only 2,4-D. Ceneng genotype showed best performance of somatic embryogenesis than others, and Slamet genotype showed lowest response both on callus induction and proliferation.   Keywords: immature cotyledons, embryonic callus, NAA, 2,4

Abstract

Anther culture provides rapid route in obtaining pure lines in a single generation through producing green haploid plants that may be spontaneously doubled. This technique has been used for crop improvement especially in rice. The objective of this research was to determine regeneration ability of eight F1s derived from crossess between upland and new plant types of rice and from their four parents through anther culture. Completely randomized design with 25 replications was used in this research. Treatments consisted of four parent lines/varieties i.e. P1 (Fatmawati and BP360E-MR-79-2), P2 (Fulan Telo Gawa and Fulan Telo Mihat) and eight F1s obtained from reciprocal crosses of P1 and P2. Callus induction medium was based on N6 medium + 2.0 mg L-1 NAA + 0.5 mg L-1  kinetin + 10-3  M Putrescine, while regeneration medium was based on MS + 0.5 mg L-1  NAA + 2.0 mg L-1  kinetin + 10-3  M Putrescine. The result indicated that F1 derived from Fatmawati x Fulan Telo Gawa (5.00% green plants per total anther) and their reciprocal (3.80% green plants per total anther) crosses were the most responsive genotypes in rice anther culture (had high anther culture ability). The F1 genotypes were more effective to produce green and doubled haploid plants in rice anther culture than their parents. From this research, 161 double haploid plants (29.81%) from total acclimated green plantlets were obtained.  Keywords: anther culture, upland rice, new plant type of rice

The study was conducted in the greenhouse of the University Farm, Bogor Agricultural University from August to October 2009. The experiment was carried out as a Factorial experiment in a Completely Randomized Design with three replications. The fi rst factor was sorghum genotypes consisted of Numbu (tolerant) and B-75 (sensitive), and the second factor was combination of lime and phosphorous fertilization consisted of: no lime-no P (R1), no lime-low P (R2), no lime-suffi cient P (R3), lime-no P (R4), lime-low P (R5) and lime-suffi cient P (R6). The results showed that all variables were signifi cantly affected by the interaction of media and genotype, except for length of shoot and total P uptake. Under low P and Al toxicity, sorghum variety Numbu showed a higher nutrient effi ciency than B-75 with ability of forming greater dry mass. The sensitive genotypes showed a higher nutrient uptake but a lower P nutrient use efficiency under Al toxicity and P defi ciency. Total P uptake and P nutrient use effi ciency were highly correlated with root growth and dry material accumulation. Keywords: sorghum, Al toxicity, P defi ciencies, P nutrient use effi ciency, P uptake

Since sorghum is not a native species of Indonesia, the genetic variability of this crop in Indonesia is low, thus, plant breeding program is required to support national sorghum development. The objectives of this study were to develop superior genotypes to improve sorghum production and quality for food, animal feed and bioethanol industry. Sorghum production is aimed at optimal use of unproductive or marginal land such as that of drought prone areas. Sorghum breeding through induced mutations was conducted at Center for the Application of Isotope and Radiation Technology, National Nuclear Energy Agency (BATAN). Durra variety was used as parental materials in the breeding program. Induced mutation was made by gamma irradiation on seed treatments. The optimal radiation dose was found to be between 300-500 Gy. Through selection processes and direct screening for drought tolerance in Gunung Kidul district, ten putative mutant lines had been selected. In dry season, the mutant lines B-68, B-72, B-95 and B-100 produced grain yields of 4.55, 4.50, 4.20 and 4.62 ton ha-1, respectively. These yields were signifi cantly higher than the original parent Durra (3.50 ton ha-1) and the control check varieties UPCA (2.68 ton ha-1) and Higari (3.75 ton ha-1). The mutant lines B-68, B-72, B-94, and B-100 were drought tolerant genotypes having a relatively higher drought index. These mutant lines were promising for further sorghum breeding and development in accordance with attempts of increasing land productivity of drought prone areas. Sorghum cultivation in such areas would promote land conservation and support sustainable agriculture development in the region. Keywords: drought tolerance, induced mutation, mutant lines, sorghum

The research objective was to study the dry matter distribution pattern of several peanut cultivars. Twenty cultivars were planted at two different locations, Cikarawang and Sawah Baru Experimental Field but at the same elevation (250 m above sea level). The cultivars were scored according to morphological and physiological characters, total N and total non-structural carbohydrates (TNC), yield and yield components. There were no statistically differences in pod yield, seed yield and harvest index between the cultivars, but there were differences in dry matter distribution between cultivars. TNC content in stem correlated positively with pod fi lling. Carbohydrates for pod fi lling presumed were derived from dry matter accumulation in early pod fi lling stage. It was concluded that the ideal growing type of peanut are early accumulated dry matter but almost no increase of dry matter accumulation in upper part of plant during seed development.
