Education Background:
1989 Ph.D. Horticultural Sciences Cornell University
1984 M.Sc. Crop Physiology Reading University
1983 B.A. Botany Oxford University
Working Experience:
2004-present Head of wheat physiology International Maize and
Wheat Improvement Center (CIMMYT), Mexico
1996-present Principal Scientist, CIMMYT
Germplasm Development and Breeding Methodology
Developed new generation of wheat lines with superior drought adaptation based on strategic crossing of complementary physiological traits –50 lines included in CIMMYT’s 27th Semi Arid Wheat Screening Nursery (SAWSN)-; best lines adopted by national wheat programs in South Asia. Identified stress-adaptive traits among germplasm collections and introgressed into elite materials to broaden genetic base of conventional wheat gene pools. For example the following pedigrees (of 27th SAWSN) incorporate Mexican landraces: WBLL4//OAX93.24.35/WBLL1, MEX94.27.1.20/3/SOKOLL//ATTILA/3*BCN Developed physiological screening protocols –using canopy temperature (CT) and spectral water index- for routine use in progeny selection. Participated in development of new statistical tools to characterize cultivar × environments interaction.
Genetic and Physiological Bases of Crop Adaptation
Developed new wheat mapping populations (e.g. Seri/Babax RILs and Wheat Association Mapping Initiative –WAMI- panel) that minimize confounding agronomic effects. Demonstrated that genes of major effect must be controlled in experimental populations to permit identification of genes of minor effect associated with complex traits. Applied physiological screening tools to high throughput phenotyping in gene discovery work. Identified common QTLs for drought and heat adaptive traits on 6 different chromosomes of Seri/Babax population, showing for the first time a common genetic basis for heat and drought tolerance, and confirming the potential generic value of MAS in stress breeding. A single QTL on chromosome 4A in Seri/Babax explained around 25% of yield variation under stress. Developed conceptual models of adaptive traits in wheat to highlight its genetic limitations in different environments.
