Geographical patterns of morphological variation in sorghum (Sorghum bicolor (L.) Moench) germplasm from Ethiopia and Eritrea : Quantitative characters
TL;DR: The results implied that environmental factors such as altitude, rainfall, temperature and growing period are important in regional variation in sorghum and the probable sources of the wide range of variation are discussed.
Book ChapterDOI
The earliest archaeological traces
TL;DR: In this paper, archaeological studies of developing technology and culture from the earliest traces to the end of the Middle Pleistocene have been conducted in Africa, focusing on what is known of long-term developments in human ecology, technology and social grouping rather than those expounded in the classics of African Palaeolithic literature.
Book ChapterDOI
Chapter 2 The domestication of cultivated barley
TL;DR: Through evolutionary processes, domestication, migration correlated with adaptation to new environmental conditions, and conscious selection by early farmers a wealth of genetic diversity was created in barley, and this rich genetic variation was the basis for modern plant breeding.

Genetic Structure of Wild and Domesticated Populations of Capsicum annuum (Solanaceae) from Northwestern Mexico Analyzed by RAPDs
Ken Oyama,Sergio Hernández-Verdugo,Carla Sánchez,Antonio González-Rodríguez,Pedro Sánchez-Peña,José Antonio Garzón-Tiznado,Alejandro Casas +6 more
TL;DR: The considerable genetic distances among cultivars as well as the high number of diagnostic bands per cultivar suggest that genetic changes associated with domestication could have resulted from artificial selection intervening in different directions, but the inclusion of more domesticated samples might clarify the nature of distinctions detected here.
Journal ArticleDOI
Global Hierarchical Gene Diversity Analysis Suggests the Fertile Crescent Is Not the Center of Origin of the Barley Scald Pathogen Rhynchosporium secalis
TL;DR: Analyses of multilocus associations, genotype diversity, and mating type frequencies indicate that sexual recombination is occurring in most of the populations, and suggests that gene flow is common at the local level while it is low between regions on the same continent, and rare between continents.
