Progress with varietal improvement in CIRAD-CA

CIRAD-CA (formerly IRCT) has participated in cotton research (mainly Gossypium hirsutum), especially cotton breeding, in a number of tropical countries in Africa, Latin America and Asia for 45 years. The work carried out has led to the creation of high quality plant material, well suited to the specific ecological conditions of the countries concerned and whose fiber qualities have progressively joined the best in their category. These varieties (ISA 205, STAM F, ISA 3 19, IRMA BLT, P 288, and glandless GL7) are grown currently on more than 1 500 000 hectares. In the past, ginning outturn, a characteristic of great economical importance, has been improved. In fiber technology, the two main spinning processes (open end and ring spinning) have produced two types of demand, firstly for strong, fine fiber about 1 "3/32 1ong (open end) and secondly for high grade cotton with long, strong fiber (combed ring spinning). In seed technology, the development of glandless varieties can improve returns from cotton growing. CIRAD-CA participates actively in the training of national teams of breeders, provides assistance to the organisation of international research networks (CORAF, Cono Sud) and makes efforts to master the new tools of biotechnology with a view to giving access in the tropical countries to the benefits from progress made in genetic science. The introduction into cotton's genomes of genes providing resistance to insects opens up a new way of research, which could limit the use of insecticide sprays, with an economical and ecological impact on production costs and protection of the environment.
