origin of the genus Pyrus ( Rubtsov, 1944 ). There are very many landraces (local cultivars) of P . pyrifolia owing to nearly 3000 years of cultivation and the complex climatic and geographical variation in China. Many landraces have unique traits
To preserve and characterize Galician (northwestern Spain) landraces of the genus Brassica L., a germplasm bank has been created at the Misión Biológica de Galicia (MBG), part of the Spanish Council for Scientific Research. To date, 246
). Unfortunately, intraspatial GS variation among landraces that adapted to cultivation in QTP and YP is rarely investigated. In this study, we investigated GS variation between the landraces grown in QTP and YP at the intraspatial scale. In flowering plants

Indication Products in Jianshi County, Hubei Province, is highly accepted by the consumer ( Giovannucci et al., 2009 ; Li et al., 2014 ). In recent years, with the continuous development of modern agriculture, growers abandoned the landrace varieties and
found as landraces in Colombia and Ecuador for many years. Adaptation of yellow passion fruit is at 500 to 1000 masl, while purple passion fruit landraces are grown at many altitudes, from 1500 to 2500 masl. Given the climate requirements and fruit

strong forces in a reduction of genetic diversity in commercially grown bitter gourd cultivars. Improved hybrid cultivars lead to further reduction in genetic diversity through displacement of landraces. For example, a significant bitter gourd area in
