Population genetics of traditional landraces of Cucurbita pepo L., 1753 in the cloud forest in Baja Verapaz, Guatemala

摘要: Little is known regarding the effect of fragmentation and human agricultural management on genetic variation gene flow Cucurbita pepo L., 1753 in moderate fragmented areas central Guatemala. We hypothesize that C. affected by forest traditional management. Therefore, we aim to determine: (1) diversity structure Cloud Forest Corridor (CFC) (2) extent admixture between commercial variety (CV) landraces (TL) pepo, (3) habitat population genetics with a landscape approach, (4) potential relationship practices CFC. detected existence high level (AR = 3.43; He = 0.50), inbreeding (Fis = 0.25) CFC (Fst = 0.16). No correlation was found. Also, found CV TL. It seems practices, mainly related seed exchange patterns, could affect populations are structured, inbreeding, show CV, an aspect its diversity. The influenced CFC, but did not. suggest special efforts should be made preserve this important indigenous food source for Guatemalan people as well their practices.
