Abstract

Agricultural crops and their wild progenitors are excellent candidates for ecophysiology studies because germplasm collections are often extensive and well described, and in its dissemination the crop may explore habitats not found in the natural distribution of the progenitor. The advent of high resolution elevational climate models has greatly improved our capacity to characterize plant habitats and study species’ adaptive responses to different stresses encountered across the distribution range. With passport data and germplasm from the ICARDA, ICRISAT and the Australian Lupin Collection, we are applying this approach to (i) search for improved reproductive chilling tolerance in chickpea (Cicer arietinum); (ii) identify adaptive strategies in stress gradients across the distribution range in wild populations of narrow-leafed lupin (Lupinus angustifolius) and (iii) genetic improvement in yellow lupin (L. luteus).
