Mapping abiotic stresses for rice in Africa: Drought, cold, iron toxicity, salinity and sodicity

Autor: Oort, P.A.J. van

Maps of abiotic stresses for rice can be useful for (1) prioritizing research and (2) identifying stress hotspots, for directing technologies and varieties to those areas where they are most needed. Large-scale maps of stresses are not available for Africa. This paper considers four abiotic stres...

Infrared thermometry for drought phenotyping of inter and intra specific upland rice lines

Autor: Guimaraes, CM Stone, LF Lorieux, M Oliveira, J.P. de Alencar, G Dias, R.A.A.

The purpose of the present study was to evaluate the use of infrared thermometry in the characterization of inter specific (Oryza glaberrima x Oryza sativa cv Caiapó) and intra specific upland rice lines for drought tolerance. The experiment, carried out at Porangatu in the State of Goiás, was su...

Assessing the Impact of Collective Marketing of Paddy Rice in Innovation Platforms by Smallholder Producers in Benin

Autor: Arouna, A.

Market access is a major constraint of smallholder rice producers in sub-Saharan Africa (SSA). There is increasing evidence that acting collectively offers one way for smallholders to participate more efficiently in the market. This chapter aimed to identify the determinants of participation in c...

In planta gene expression analysis of Xanthomonas oryzae pathovar oryzae, African strain MAI1

Autor: Soto Suárez, M. Bernal, D. González, C. Szurek, B Guyot, R Tohme, Joseph M. Verdier, Valérie

Background: Bacterial leaf blight causes significant yield losses in rice crops throughout Asia and Africa. Although both the Asian and African strains of the pathogen, Xanthomonas oryzae pv. oryzae (Xoo), induce similar symptoms, they are nevertheless genetically different, with the African stra...

Association of Burkholderia glumae and B. gladioli with panicle blight symptoms on rice in Panama

Autor: Nandakumar, R Rush, MC Correa Victoria, Fernando J.

Panicle blight of rice, caused by Burkholderia glumae, has been a serious problem on rice in Japan since 1955. It has been reported from other rice-producing countries around the world and recently was reported on rice in the southern United States (2). A rice producer in Panama contacted us to v...

Bacterial sheath brown rot of rice caused by Pseudomonas fuscovaginae in Latin America

Autor: Zeigler, Robert S. Álvarez, E.

Many types of symptoms associated with discolored grain have been observed on rice (Oryza sativa) sheaths, leaves, and grain in Mexico, Guatemala, Panama, Surinam, Colombia, Peru, and Brazil. These include brown necrotic lesions ranging from small specks to large brown to maroon sheath blotches. ...

Assessment of genetic diversity in Venezuelan rice cultivars using simple sequence repeats markers

Autor: Ghneim-Herrera, Thaura Posso Duque, D Pérez Almeida, I. Torrealba N., G.T. Pieters, AJ Martínez Racines, César Pompilio Tohme, Joseph M.

In Venezuela, pedigree analyses indicate that the rice varieties currently under cultivation are closely related. Effective breeding programs, based on knowledge of the genetic diversity of cultivars, are needed to broaden the genetic bases of rice germplasm in the country. In this study, we used...

Seven years of conservation agriculture in a rice–wheat rotation of Eastern Gangetic Plains of South Asia: Yield trends and economic profitability

Autor: Jat, Kumar Raj Sapkota, Tek Bahadur Singh RG Jat, Mangi Lal Kumar, M. Gupta RK

Water, energy and labour scarcity, increasing cost of production, diminishing farm profits and uncertain weather events are major challenges faced by the farmers under intensive tillage based conventional rice–wheat (RW) production system of Indo-Gangetic Plains (IGP) in South Asia. To address th...

Comparison of rice lines derived through anther culture and the pedigree method in relation to blast (Pyricularia grisea Sacc.) resistance

Autor: Martínez Racines, César Pompilio Correa Victoria, Fernando J. Amézquita, María Cristina Tulande Valencia, Edgar Lema, G Zeigler, Robert S.

Crosses were made between Fanny (highly susceptible to blast) and 11 cultivars differing in blast resistance. Using the pedigree method (PM) segregating generations were evaluated and selected for blast resistance. Via anther culture (AC), doubled-haploids were obtained from F1 plants and from F2...

Epidemiological implications of the spectrum of resistance to rice blast

Autor: Sang Won Ahn Ou, SH

The infection efficiency and the infection rate of the spore population of Pyricularia oryzae was lower if the percentage of races to which each cultivar was resistant was high. It appears that cultivars with resistance to a high percentage of the races of the pathogen behaved as expected for “ho...
