3 | Cassava germplasm improved for physiological and biotic traits | Germplasm | BC2 progenies with excellent delayed PPD identified for establishment in vitro and shipment to partners in Africa; Several wild Manihot species and inter-specific hybrids with resistance to cassava green mites identified, accessions of M. esculenta sub spp flabellifolia with resistance to whiteflies identified; Development of a new set of CMD resistant materials with enhanced nutritional quality for shipment to partners in Africa; The main objective of project is to accelerate the process of introgression of useful genes from wild relatives into cassava via a modified Advance Back Cross QTL (ABC-QTL) breeding scheme. | Germplasm to be used in a SP3 commissioned project 2003 (Cassava Nigeria) | Contact A.

4 | Drought tolerant contrasting cassava varieties | Germplasm | In order to elucidate the mechanisms of cassava which has remarkable tolerance to drought and to determine the best traits to be used in breeding programmes for drought tolerance, selected contrasting varieties have been screened and evaluated in four representative semi-arid environments in Brazil, Colombia, Tanzania and Ghana. | Cassava breeding materials in Brazil | Contact, A.

6 | UMCASS33. a disease-resistant, high-yielding cassava variety from Nigeria | Germplasm | Released in December 2010, UMCASS33 brings together favorable quality and agronomic characteristics from South American and African cassava. Selected South American cassava provided a higher nutritional content, while African cassava conferred resiliencyand CMD resistantce . CIAT provided the South American cassava, while the local variety resistant to cassava mosaic disease (CMD) was developed from material obtained from the International Institute of Tropical Agriculture (IITA). UMCASS33 has indicated higher yields and tolerance to acid soils conferred from the South American parentage and CMD disease resistance from the African. | Cultivation by Nigerian farmers and breeding material for elite lines. | Contact Dr. Emmanuel Okogbenin or Dr. Cheidozie Egesi, National Root Crops Research Institute (NRCRI) at Umudike, Nigeria | eokogbenin@ yahoo.com This email address is being protected from spambots.

7 | Training course materials on phenotyping | Training Materials | Training course : phenotyping and water deficit. A ooklet of the course, distributed to participants with copy to GCP; CD rom with all power point presentations, conclusions of the course and spreadsheets for calculating environmental data and soil water balance. Distributed to participants with copy to GCP; six A4 pages presenting techniques (measurements of plant temperature, of evaporative demand, of soil water content, of intercepted radiation, calculation of evapotranspiration); The training course aimed at providing participants with theoretical and practical elements for these choices. Twenty three scientists (level : PhD or master) participated to the course, 6 from Africa, 6 from south Asia, 4 from east Asia, four from Latin America and 3 from Europe. The latter were participants to ongoing GCP projects which received no financial support from the GCP. The course lasted 8 working days (from 3 to 12 July 2006) and the time was split into three parts of similar durations (i) lectures, aimed at providing and discussing the theoretical frameworks, (ii) practical sessions in the greenhouse or in the field aimed at a direct contact with the tools involved in phenotyping, (iii) computer sessions in which each participant could work on practical examples and directly test methods of analysis and reasoning. The course consisted in two sessions : "Characterising the plant environment and the stress" with lecures, a practical experience of measurements in greenhouse and field and computer sessions, and "Assessing phenotypes : trait evaluation" with lectures, a field session and two days of computer sessions. | General training on phenotyping | CD rom with all power point presentations, conclusions of the course and spreadsheets for calculating environmental data and soil water balance on demand from GCP (www.generationcp.org) | This email address is being protected from spambots.
