Basic study for the appropriate cultivation method of groundnut (Arachis hypogaea L.) in Tokachi region. OAK
秋本, 正博; 中田, 翔子; 熊田, 総佳; 逵本, 秀久; 小林, 規人; 平等, 聡; 田中, 一郎.
十勝地方におけるラッカセイ生産の可能性を模索するため、帯広畜産大学実験圃場でラッカセイ品種「千葉半立」、「ナカテユタカ」、および「おおまさり」の栽培を行った。栽植方法(直播、あるいは移植)、および栽植密度(標準植:5.1 株/ ㎡、あるいは密植:7.7 株/ ㎡)の組合せによる4 試験区を設け、2016 年5 月23 日にそれぞれの品種の栽培を開始した。茎葉の黄変期に収穫を行い、収量構成要素や子実収量の評価を行った。千葉半立とナカテユタカでは、子実収量に対する栽植方法と栽植密度の効果が認められた。両品種とも移植を行った試験区で直播を行った試験区に比べ収量が高かった。これは、移植を行うことで単位面積当たりの稔実粒数が増加することに起因する。また、両品種とも密植を行った試験区で標準植を行った試験区に比べ収量が高かった。千葉半立は半立ち性、ナカテユタカは立性の草型をもつため光競合を起こしにくく、十勝地方で栽培する場合には都府県の慣行法よりも栽植密度を高めることで土地利用効率が高まり、子実収量が改善されると考えられる。おおまさりでは、子実収量に対して栽植方法の効果のみが認められた。移植を行うことで直播を行った場合に比べ総稔実粒数や1000 粒重が高まり、子実収量が増加した。一方、おおまさりでは子実収量に対する栽植密度の効果が認められなかった。おおまさりは伏性の草型を持つため光競合が起こりやすく、十勝地方においても密植条件下では密度障害が生じ増収につながらないと考えられる。千葉半立とナカテユタカでは、移植・密植の処理組合せによる試験区で、おおまさりでは、移植・標準植、および移植・密植の処理組合せによる試験区でそれぞれ最も子実収量が高く、いずれも子実収量の全国平均(180g/...

Characterization of Brazilian accessions of wild Arachis species of section Arachis (Fabaceae) using heterochromatin detection and fluorescence in situ hybridization (FISH) Genet. Mol. Biol.
Custódio,Adriana Regina; Seijo,Guillermo; Valls,José Francisco Montenegro.
The cytogenetic characterization of Arachis species is useful for assessing the genomes present in this genus, for establishing the relationship among their representatives and for understanding the variability in the available germplasm. In this study, we used fluorescence in situ hybridization (FISH) to examine the distribution patterns of heterochromatin and rDNA genes in 12 Brazilian accessions of five species of the taxonomic section Arachis. The heterochromatic pattern varied considerably among the species: complements with centromeric bands in all of the chromosomes (A. hoehnei) and complements completely devoid of heterochromatin (A. gregoryi, A. magna) were observed. The number of 45S rDNA loci ranged from two (A. gregoryi) to eight (A....

Characterization of rust, early and late leaf spot resistance in wild and cultivated peanut germplasm Scientia Agricola
Fávero,Alessandra Pereira; Moraes,Sérgio Almeida de; Garcia,Antonio Augusto Franco; Valls,José Francisco Montenegro; Vello,Natal Antonio.
Groundnut (Arachis hypogaea) has an AB genome and is one of the most important oil crops in the world. The main constraints of crop management in Brazil are fungal diseases. Several species of the genus Arachis are resistant to pests and diseases. The objective of our experiments was to identify wild species belonging to the taxonomic section Arachis with either A or B (or " non-A" ) genomes that are resistant to early leaf spot (Cercospora arachidicola), late leaf spot (Cercosporidium personatum) and rust (Puccinia arachidis). For the identification of genotypes resistant to fungal diseases, bioassays with detached leaves were done in laboratory conditions, with artificial inoculation, a controlled temperature of 25ºC and a photoperiod of 10 h light/14 h...

Compatibility of Azospirillum brasilense and Pseudomonas fluorescens in growth promotion of groundnut ( Arachis hypogea L.) Anais da ABC (AABC)
PRASAD,ANDHARE A.; BABU,SUBRAMANIAN.
ABSTRACT We attempted to study the compatibility among plant beneficial bacteria in the culture level by growing them near in the nutrient agar plates. Among all the bacteria tested, Rhizobium was found to inhibit the growth of other bacteria. From the compatible group of PGPR, we have selected one biofertilizer (Azospirillum brasilense strain TNAU) and one biocontrol agent (Pseudomonas fluorescens strain PF1) for further studies in the pot culture. We have also developed a bioformulation which is talc powder based, for individual bacteria and mixed culture. This formulation was used as seed treatment, soil application, seedling root dip and foliar spray in groundnut crop in vitro germination conditions. A. brasilense was found to enhance the tap root...

Development and Evaluation of a Fish Feed Mixer CIGR Journal
ADEBUKOLA, ADENIGBA ADEMOLA.
Abstract A Fish feed mixing machine was designed, developed and the effect of speed and retention time on the performance of the mixer was evaluated. The mixing system was tested using three fish feed ingredients; bone meal, groundnut cake and maize grain which was purchased from the market in Akure, Ondo State, Nigeria. The moisture content of the bought ingredients was determined to be 13.1%, 14.7% and 17.5% moisture content dry basis respectively. The mixer was tested using a feed component of three equal measures of 10 kg of ground corn (maize), milled groundnut cake and bone meal which were initially retained on 2 mm, 850 µm and 150 µm sieve respectively. The experiment was replicated thrice at four retention time (5 min, 10 min, 15 min and 20 min)...

Effects of in vitro triacontanol on growth, antioxidant enzymes, and photosynthetic characteristics in Arachis hypogaea L. Braz. J. Plant Physiol.
Verma,Aman; Malik,Chander Parkash; Gupta,Vijay Kumar; Bajaj,Bhavneet Kaur.
In vitro effects of triacontanol (TRIA) on antioxidant enzymes and photosynthetic characteristics were studied in Arachis hypogaea L. cultivars (M-13 and PBS24030). The in vitro impact of TRIA on multiplication potential was also evaluated, which was found to be best at 2.0 ml L-1 TRIA in combination with 6- Benzyl adenine (BA, 3 mg L-1) in both the groundnut cultivars. Rhizogenesis was observed in almost all the TRIA treated cultures in both the cultivars. Moreover, shoots failed to set roots, in the presence of BA. Total chlorophyll content, total soluble sugars, total soluble proteins and ascorbate peroxidase (APX; EC 1.11.1.11) activity were found to be increasing with increasing concentrations of TRIA, whether alone or in combination with BA, however,...

Influence of substrates and in vitro preconditioning treatments on ex vitro acclimatization of Arachis retusa PAB
Pacheco,Georgia; Gagliardi,Rachel Fátima; Cogliatti,Mariana Buturini; Manhães,Harlen Barreira; Carneiro,Leonardo Alves; Valls,José Francisco Montenegro; Mansur,Elisabeth.
The objective of this work was to evaluate the influence of substrate and preconditioning treatments on the acclimatization of in vitro plants of Arachis retusa. Plants were transferred to Plantmax or sand, and fertilized with Hoagland's nutrient solution. Plants maintained in sand, with or without fertilizer, showed the highest survival rates. In order to evaluate the influence of in vitro preconditioning treatments, stem segments were cultured on MS medium supplemented with different sucrose concentrations. The highest survival and developmental rates were observed in plants from two accessions cultured on MS supplemented with 1.5% and 3% sucrose. Flowering and fruit production were observed after five months.

Isolation of simple sequence repeats from groundnut Electron. J. Biotechnol.
Tang Wang,Chuan; Dao Yang,Xin; Xu Chen,Dian; Lin Yu,Shan; Zhen Liu,Guang; Yi Tang,Yue; Zhi Xu,Jian.
SSRs have proved to be the most powerful tool for variety identification in groundnut of similar origin, and have much potential in genetic and breeding studies. To facilitate SSR discovery in groundnut, we proposed a highly simplified SSR isolation protocol based on multiple enzyme digestion/ligation, mixed biotin-labeled probes and streptavidin coated magnetic beads hybridization capture strategy. Of the 272 colonies randomly picked for sequencing, 119 were found to have unique SSR inserts

MODELING WORLD PEANUT PRODUCT MARKETS: A TOOL FOR AGRICULTURAL TRADE POLICY ANALYSIS AgEcon
Beghin, John C.; Matthey, Holger.
This paper presents a new partial-equilibrium, multi-market international model developed to analyze policies affecting peanut products markets. The model covers four goods (food-quality peanuts, crush-quality peanuts, peanut oil, and groundnut cake) in 13 countries/regions (Argentina, Canada, China, the EU-15, the Gambia, India, Malawi, Mexico, Nigeria, Senegal, South Africa, the United States, and Rest of World). Welfare is evaluated by looking at consumers' equivalent variation, quasi-profits in farming (peanut farming, livestock), quasi-profits in crushing, and taxpayers' revenues and outlays implied by distortions. We calibrate the model for three recent years (1999/2000, 2000/01, and 2001/02) on historical data. We illustrate the model's...

Molecular characterisation of Aspergillus flavus isolates from peanut fields in India using AFLP BJM
Singh,Diwakar; Radhakrishnan,T.; Kumar,Vinod; Bagwan,N.B.; Basu,M.S.; Dobaria,J.R.; Mishra,Gyan P.; Chanda,S.V..
Aflatoxin contamination of peanut, due to infection by Aspergillus flavus, is a major problem of rain-fed agriculture in India. In the present study, molecular characterisation of 187 Aspergillus flavus isolates, which were sampled from the peanut fields of Gujarat state in India, was performed using AFLP markers. On a pooled cluster analysis, the markers could successfully discriminate among the ‘A’, ‘B’ and ‘G’ group A. flavus isolates. PCoA analysis also showed equivalent results to the cluster analysis. Most of the isolates from one district could be clustered together, which indicated genetic similarity among the isolates. Further, a lot of genetic variability was observed within a district and within a group. The results of AMOVA test revealed that...

Simple method to prepare DNA templates from a slice of peanut cotyledonary tissue for Polymerase Chain Reaction Electron. J. Biotechnol.
Yu,Shu Tao; Wang,Chuan Tang; Yu,Shan Lin; Wang,Xiu Zhen; Tang,Yue Yi; Chen,Dian Xu; Zhang,Jian Cheng.
An efficient DNA extraction method was developed for peanut seed, where only 3-5 mg cotyledonary tissue was enough for more than 50 PCR reactions with a reaction volume of 15 μl. Both low copy number and high copy number DNA sequences were successfully amplified. Processing one seed sample only took about half an hour. Sampling had no significant effects on germination and development. The DNA extraction method makes it possible to identify transformants and conduct molecular marker studies prior to sowing, and thus may greatly hasten research progress.
