Abstract: |
In order to find good parent materials of pea for drought resistant breeding and suitable improved varieties (lines) for rainfed farming region production, in the trial fields of Dingxi Dryland Agro-scientific Research and Extension Center (2008~2009), drought-resistance identification and selection were made for 78 kinds of materials of pea germplasm resources from seven major pea-producing provinces using natural identification method, to determine different varieties (lines) under drought conditions in the consolidated results of drought-resistance, agronomic traits and yield performance. The results indicate that 17 kinds of the materials are typically drought resistant, 6 are drought-resistant, and 10 are moderately drought-resistant; Among all the drought-resistant materials, 8 kinds are superior in every selective index, such as strong drought-resis tance and stable yield. |
