Bo Liu,Xuewei Bi,Yuqi He,Xiaoming LiIn his landmark treatise “L’Origine des Plantes Cultivées”, de CANDOLLE (1882) suggested that botanical, archaeological, historical, and linguistic data can provide evidence on the area of domestication of crop plants. These types of data are still considered at the present time by crop evolutionists (e.g., PICKERSGILL, 1977).

Decentralising Public Service ManagementExperiments on intraspecific genetic variability of plant species have revealed complex spatial patterns of variability among and within populations ranging from clines at one end, and ecotypes, to the other (for a review, see Briggs and Walters, 1984).

Germplasm ExplorationMuch has been written on the subject of germplasm collection (see HAWKES ., 1983, for a revised bibliography on the subject). However, less literature deals directly with the germplasm of . beans. Aspects of . germplasm exploration and their consequences for subsequent germplasm use and management will be discussed here.
