Wildland collection, population development, and genetic manipulation of native rangeland grasses in the Intermountain West USA in accordance with the AOSCA pre‐variety germplasm system

摘要：

In the Intermountain West USA, a high demand for native plant materials exists, but customer expectations for native plant materials are diverse ( Jones, 2003 ).Some customers spurn genetically manipulated or non‐local plant materials, while others accept manipulation or non‐local origin when necessary to achieve satisfactory performance.For certification purposes, the AOSCA pre‐variety germplasm system accommodates manipulated and natural.tracks, various degrees of testing prior to release, and seed production located at both wildland in situ and cultivated ex situ sites (Young et al.,2005).Native plant material development by USDA‐ARS at Logan, Utah seeks to deliver the best‐performing materials possible that respect the variety of constraints or lack of constraints imposed by the customers.
