豌豆种质资源抗旱性鉴选与利用价值分析

Research and utilization of drought-resistance of pea germplasm

为了鉴定筛选抗旱的豌豆种质资源及适宜在旱作雨养农业区生产中应用的优良品种(系),2008～2009年,在定西市旱农中心旱地试验地,采用田间自然鉴定方法,对来自全国主要豌豆产区七个省(市)的78份材料进行了抗旱性鉴定及筛选,以确定不同品种(系)在干旱条件下的抗旱性、综合农艺性状及产量表现。结果表明:17份材料属典型抗旱材料,6份为抗旱材料,10份为中等抗旱材料;在所有抗旱材料中,有8份材料各项筛选指标均较高,属抗旱性强、稳产性好的材料。

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-resistance and stable yield.
