ANNEX 1 Glossary <strong>of</strong> selected terms<br />

Landraces, traditional varieties and farmers’ varieties.<br />

These terms are used <strong>in</strong>terchangeably and refer to local varieties <strong>of</strong> domesticated plant species,<br />

which were bred and selected by farmers over time. They are genetically diverse, dynamic, have<br />

specific characteristics, and are highly adapted to the environment <strong>in</strong> which they have evolved.<br />

They have a high capacity to tolerate environmental stress and therefore produce very stable yields.<br />

Farmers’ varieties are always open-poll<strong>in</strong>ated (can be cross- or self-poll<strong>in</strong>ated).<br />

Open-Poll<strong>in</strong>ated Varieties (OPV)<br />

Open-poll<strong>in</strong>ated plants are those that require poll<strong>in</strong>ation by the w<strong>in</strong>d, <strong>in</strong>sects, or the farmer to set<br />

fruit and produce <strong>seed</strong>s. In some cases, the plant will produce both male and female flowers on the<br />

same plant, which means self-poll<strong>in</strong>ation can take place. In other cases, cross-poll<strong>in</strong>ation is needed.<br />

The key issue with OPVs is that farmers can save <strong>seed</strong> and the <strong>of</strong>fspr<strong>in</strong>g will cont<strong>in</strong>ue to be viable.<br />

Self-Poll<strong>in</strong>ated plants<br />

Self-poll<strong>in</strong>ated plants are plants where the pollen and stigma are present <strong>in</strong> the same flower. Often,<br />

all that’s required for poll<strong>in</strong>ation is the act <strong>of</strong> the flower open<strong>in</strong>g, which will transfer pollen to the<br />

stigma. Self-poll<strong>in</strong>ated plants produce true from <strong>seed</strong>.<br />

Cross-poll<strong>in</strong>ated plants<br />

Cross-poll<strong>in</strong>ation is where the pollen and stigma are produced by different flowers and the pollen<br />

has to travel over a distance to fertilise the plant.<br />

Farmers’ rights<br />

Farmers’ rights are those rights aris<strong>in</strong>g from the past, present and future contributions <strong>of</strong> farmers <strong>in</strong><br />

conserv<strong>in</strong>g, improv<strong>in</strong>g and mak<strong>in</strong>g available genetic resources, particularly those <strong>in</strong> the centres <strong>of</strong><br />

orig<strong>in</strong>/diversity. Additionally, the term refers to farmers’ rights to use, exchange and sell farm saved<br />

<strong>seed</strong> and other propagat<strong>in</strong>g material, and to participate <strong>in</strong> decision-mak<strong>in</strong>g.<br />

Hybrids<br />

Hybrids can only be produced by cross-poll<strong>in</strong>at<strong>in</strong>g plant varieties. An F1 hybrid is produced by<br />

cross<strong>in</strong>g and backcross<strong>in</strong>g the pure l<strong>in</strong>es <strong>of</strong> different varieties over a number <strong>of</strong> seasons. When you<br />

plant an F1 hybrid <strong>seed</strong>, you get a plant that has the attributes the breeder has bred <strong>in</strong>to the <strong>seed</strong>,<br />

but if you save the <strong>seed</strong>, the next generation will not breed true: i.e. its characteristics will revert<br />

back to one <strong>of</strong> the orig<strong>in</strong>al parent l<strong>in</strong>es, which can vary a great deal. It is not viable to save hybrid<br />

<strong>seed</strong>s.<br />
