Genetics for Plant Breeding

In the first part, this module aims to give a general culture around plant breeding. A historical analysis of plant breeding is carried out in order to initiate a reflection on the evolution of the speed of genetic progress, ideotypes and also the profession of breeder.

In a second part, the different methodologies for improving germplasms and for creating are described. The patterns conventionally used in selection such as backcross, recurring selections, pedigree selections and diallele tests are described in detail. Part of the course is also used to give tools to reason / follow these selection schemes (e.g. AGC/AUC calculations, heritability calculations, genotype evaluation statistics, etc.). These theoretical courses are also illustrated by courses given by different actors in plant breeding.

Example of interventions:

• Arnaud Boisnard (CFR): course on rice breeding in the Camargues
• Frederic Bakry (CIRAD): course on banana selection
• André Clement-Demange (CIRAD): course on rubber tree selection
• Vincent Gensollen (GEVES): visit of GEVES Montpellier

Experimentation in conservative selection is addressed in a third part of the course. The different methods of seed production and the different ways of improving seed production and quality are dealt with through the intervention of professionals.

Examples of interventions:

• Sophie Colénot (Bayer) experience in seed production
• David Martinez (Clause Hm) seed quality experimentation

In addition to the lectures, students must present a presentation in which they must develop a breeding program for a crop species. To prepare for this presentation, the student must put into practice what he has seen in class and also have exchanges with selectors.

• Acquire the basics of genetics and plant breeding to start a business as an assistant breeder.
• Acquire the knowledge needed for experimentation in seed production.
• Acquire a general knowledge of plant improvement.
• Analyze a scientific article.
