Study Guide, CIAT, Apartado A_reo 6713, Cali, Colombia; Series 04eB-12.03, 1981, 36 pp.

An effective seed program comprises many and diverse elements and activities which must be coordinated to attain the principal objective: produce and distribute good quality seed of improved varieties.

Therefore, the success of a seed program is founded on producing and providing a sufficient quantity of good quality seed, at the required time, at a reasonable cost, and at a location where it is needed, so that the majority of the farmers can enjoy the benefits provided by using this seed.

This study guide is complementary material to the audiotutorial unit "Good-Quality Bean Seed". Its principal objective is to provide useful information relating to the practices of production, quality control and processing of bean seed.

The audiotutorial unit is a translation of the Spanish unit entitled "Semilla de Frijol de Buena Calidad" which was produced by CIAT through a special project on the development and utilization of training materials on improved agricultural production technology.

The handbook contains the following chapters:

- Objectives
- Introduction
- What is Good Quality Seed?
- Varietal purity
- Physical purity
- Good germination
- Freedom from seed-borne diseases
- What is needed to produce Good Quality Bean Seed?
- Varietal pure seed
- Freedom from seed-borne diseases
- A site that provides an unsuitable environment for development of pathogenic organisms
- A suitable field
- Special management of the crop
- Removal of foreign, off-type and diseased plants
- Harvest of the seed
- Steps to follow after harvesting Good Quality Seed
- Drying
- Cleaning
- Treatment
- Sampling
- Evaluation
- Storage
- Transport
- Activities of Different Groups in Obtaining Good Quality Seed
- Seed certification authorities
- Research programs
- Seed growers, seed enterprises and marketing groups
- Evaluation
- Bibliography

This handbook together with the audiotutorial unit provides useful information for the practice of quality bean production.
