Characterization of O. glaberrima genetic resources and utilization in marker assisted composite population breeding.- Conference Paper uri icon

Resumen

  • Before the launching of the Generation Challenge Program, this activity was presented and discussed during the 2003 CIO/CIAT meeting held in Montpellier. After the launching of the GCP, it was submitted and accepted for one year of funding. The activity falls into the Sub-Project 3 (SP3) "Gene Transfer and Crop Improvement", Cluster 2a 5 (C2a 5) "Marker-assisted Selection of Rice". The principal objective of the activity is to increase the genetic diversity of Oryza sativa composite populations targeting the aerobic rice ecosystem. These rice composite populations already existed and were developed using a recessive male-sterile gene. The new variability comes from fixed inter-specific lines from the cross between the aerobic rice variety Caiapo and an O. glaberrima accession. The project is taking advantage of existing advanced breeding methods (composite population breeding, molecular marker techniques and inter-specific lines) to merge them for the development of rice lines for the aerobic rice ecosystems. The project outputs will benefit Latin American NARS and WARDA.
