Chickpea (Cicer arietinum) developed as a post-rainy season, spring-sown crop early in its evolution and spread into warm subtropical regions, in contrast to its wild relatives that have remained as winter annuals in West and Central Asia. To test whether these different life cycles selected for different phenological strategies in wild and cultivated Cicer, germplasm from a wide range of habitats was subjected to different cold treatments (vernalisation, control) at germination, and phenology evaluated at warm and cool field sites (14.8–15.1°C and 13.1°C, respectively). All wild Cicer species, except for C. yamashitae, responded positively to vernalisation and accelerated the dates of flowering, podding, and maturity. There was no vernalisation response in cultivated chickpea, whereas C. arietinum/C. echinospermum and C. arietinum/C. reticulatum interspecific hybrids were intermediate, flowering 6–16 days earlier after vernalisation. Relative podding dates differed between sites. Chickpea podded earlier than most vernalised wild species under warm conditions, but not at the cool site. Regression against post-anthesis temperature showed that the delay in podding was consistent with a lack of cold tolerance in the cultigen. The interspecific hybrids were significantly more cold tolerant than chickpea, and the wild species were almost insensitive to the temperature range recorded at the cool site. Vernalisation responsiveness and a greater tolerance of low temperatures during the reproductive phase demonstrate that the annual wild Cicer species harbour important traits that can be used to widen adaptation in the cultigen, and may help to improve the performance of chickpea as a Mediterranean cool-season crop.

Core subsets have been selected for the USDA chickpea (Cicer arietinum), lentil (Lens culinaris), and pea (Pisum sativum) germplasm collections. These subsets are specifically intended to increase the efficiency of the utilization of the entire collections of these taxa. The cores consist of 13% of the 3873 chickpeas, 12% of the 2390 lentils, and 17.5% of the 2886 pea accessions. They were selected by a proportional logarithmic model, and also contain additional accessions based upon documented concentrations of diversity. Each core has been screened for disease reactions, and results suggest that the cores can effectively direct germplasm users toward portions of the entire collections that contain resistant germplasm. These cores have also been useful for those interested in assessing the adaptation potential of these crops in new environments, because the entire range of adaptation is represented. Although cores may not always enhance access to germplasm with unique or extremely rare characteristics, the legume cores have been very useful for directing users toward desirable germplasm from defined geographic areas, and assisting users at the preliminary stages of germplasm evaluation.
