STOILOVA, Tz. and I. KIRYAKOV, 2000. Study of domestic and introduced samples of field beans in Bulgaria. Bulg. J. Agric. Sci., 6: 21-28

Common bean is one of the species of wide occurrence, grown in different geographical areas such as the tropics, subtropics and temperate zones where it is a major component of the population's diet.
Domestic cultivars and populations are characterized with great polymorphism resulting from the introduction, the spontaneous formation process and long-term people's selection (Ganeva, 1978). They have a considerable potential value to our country. Formed in the course of many years and adapted to the conditions of the country, domestic beans are a valuable gene pool that can be widely used in selection activities (Patenova, 1980).
Many scientists have done research on domestic beans, namely: Gradinarov, 1939; Rachinski, 1963; Radkov, 1977; Patenova, 1980; Patenova and Delchev, 1982 and Mitranov, 1986.
The objective of the present research was to study the germplasm of domestic and foreign origin in order to reveal its genetic variability and successful utilization in the selection process.

Key words: beans, genetic resources, resistance
