“These four Japanese introductions probably were of the Japonica ecotype.”

“Its use has also been extended to protect selected kinds of this pepper ecotype from unwanted hybridisation.”

“The morphological differences are genetically determined and it is thus possible that the turlough population is a distinct ecotype adapted to this unusual habitat.”

“It was assumed that factors that are under photoperiodic control would show a clinal order among the ecotypes.”

“To study the genealogical relationship among the ecotypes, we apply the theory of coalescence processes in the following way.”

“Geographically isolated populations often have evolved into distinct ecotypes that differ in morphological, life history, or behavioral traits.”
