Morphological and phenological comparisons of two Hopi maize varieties conserved in situ and ex situ

摘要: Over the last twenty-five years, crop genetic resources (CGR) have been preserved in genebanks around world for use by formal plant breeders. Recently conservation of folk varieties direct farmer-breeders traditional agricultural communities has suggested as another purpose CGR conservation. While both and ex situ programs proposed to meet needs breeders farming communities, goals two groups are different. Formal seek maximum allelic diversity while interested population structure that provide local adaptation. Based on morphological phenological data analyzed this study Hopi maize conserved situ, it appears shift drift occurred populations different from those maintained situ. These findings suggest strategies must be re-evaluated light specific sought.
