In many part of the region durum wheat production is replaced by modern cultivars; landraces are only cultivated by farmers in very limited areas [23,1].
These new lines--ranging from small Tabasco-type peppers and miniature bells to large, orange, banana shaped peppers--were developed from a diverse collection of Capsicum landraces from India and select heirloom peppers," says Stommel.
The objective of this study was to evaluate the applicability of the parameter(s) derived from the degree of cell membrane stability, chlorophyll content and fluorescence kinetics to evaluate drought stress response of durum wheat landraces and distinguish drought tolerance among the tested durum wheat landraces.
Native varieties are commonly known by scientists as landraces.

In-vitro starch digestibility (IVSD): In the present study, the IVSD values of the selected bean landraces in uncooked as well as processed conditions were compared (Tab-6).
This approach to conservation is premised on the idea that these contexts are important to the continued evolution and conservation of crop landraces, (1) and that the involvement and participation of local people are crucial to the success of conservation efforts.
In a study of corn landraces (crops selected for their adaptations to specific locations and their culinary characteristics) in Northern Oaxaca, Ignacio Chapela, a professor in the Department of Environmental Science, Policy and Management at UC Berkeley published a paper in Nature providing evidence for the presence of transgenic DNA in these landraces.
However, equally troubling is the destruction of landraces, which are variations of major crops grown by small-scale farmers, and the destruction of wild relatives to major crops.
