Academic background

Ronan Xavier Corrêa graduate in Agronomy (1992), Master (1995) and PhD in Genetics and Improvement (1999) by the Federal University of Viçosa, Brazil. He studied soybean and common bean resistance to diseases. He was visiting Professor at the State University of Montes Claros (1999). He was visiting research (1st sabbatical leave) in genomics and breeding of melon resistance to CMV, in the Centre di Reserca en Agrigenòmica – CRAG / UAB / IRTA (Spain, 2012). Currently, he is effective Professor of Genetics in State University of Santa Cruz (2000 to present).



Undergraduate: CIB146 – Molecular genetics, Graduate programs: CIB081 – Genetic mapping, and CIB026 – Genetics of plant disease resistance.

Interest in Research

Ronan Xavier Corrêa develops research projects in molecular genetics applied to plant improvement for resistance to disease, and to conservation of biodiversity. His main approaches include:


  • Mapping of plant disease resistance genes.
  • Characterization and evaluation of plant germplasm for breeding.
  • Genetic diversity applied to conservation.
  • [Starting 2015!] Molecular analysis of plant-pathogen interaction.


He has studied on characterization of cocoa germplasm and genetic mapping using molecular markers. Under scientific partnerships with researchers in Brazil, Spain and the USA, he works in molecular breeding for resistance in cocoa, mango, passion fruit and melon to different diseases. Also, he studied the genetic diversity of Brazilwood (Caesalpinia echinata) based on SSR and cpDNA, and genetic conservation of endangered species. Currently, his priority studies aim characterization of disease resistance, genetic diversity and differential gene expression (RT-PCR and proteomics) in pathosystems melon-CMV, cocoa-Phytophthora and cocoa-Ceratocistys. He published 71 scientific papers (1996-2016) in Brazilian (40) and International (31) Journals.


Supervision of students

He has supervised 6 PhD students and 21 Masters Research students. Currently, he supervises 5 PhD students and 4 Master research students.
