The International Wheat Information System (IWIS™), curated by CIMMYT, contains data gathered from 1976 to the present, from multiple providers situated in countries throughout the world. International Wheat Improvement Network cooperators and partners have provided the genotypic and phenotypic data contained in IWIS.

IWIS is currently a stand-alone, main-frame database. Plans are underway to upgrade IWIS to enabled remote, web access. The IWIS compact disk (Fox et al., 1996), now available in a 4th edition (Payne et al., 2002), duplicated data querying capabilities and some of the genealogical diagnostics of the mainframe version.

Access to all phenotypic trait data summary tables, collected on germplasm contained in nurseries distributed by IWIN from 1998 - present, is available below. Access to data on other nurseries is available upon request. As new data is received and entered into IWIS, these phenotypic data summary tables will be updated on an approximately bi-month basis until "live" web-accessibility is available.

Barley data in IWIS were included with the cooperation of the ICARDA/CIMMYT Barley Improvement Program.
