甘肃省干旱地区抗逆农作物种质资源调查与分析

Investigation and Analysis of Stress-tolerant Crop Germplasm Resources in Arid Region of Gansu Province

调查、收集了甘肃省干旱地区抗逆农作物种质资源,为甘肃抗逆农作物种质资源保护、研究、利用提供基础材料。2011-2013年采用查阅文献、访问和实地调查相结合的方法,对分布在甘肃干旱地区18个县(市、区)、48个乡(镇)、81个行政村的抗逆农作物种质资源的保存及利用现状进行了调查,并对种质进行了收集。共收集到粮食作物、经济作物、蔬菜及野生资源材料845份,分属16科46属62种,其中抗旱种质27份,耐盐碱种质4份,高抗锈病种质14份。本文对调查地区抗逆农作物种质资源现状、消长情况及原因和调查、收集到的资源种类及其利用价值进行了分析,并对甘肃省干旱地区抗逆农作物种质资源的保护、开发和利用进行了讨论。

In order to provide base material on the conservation, research and development of stress-tolerant crop germplasm resources. Through referring literatures, visiting and field survey to investigate of stress-tolerant crop germplasm resources during 2011-2013 in arid region of Gansu province, including 81 villages in 48 towns of 18 counties. The survey collected local varieties and wild resources of grain crops, economic crops, vegetables, with the total 845 collected samples which belonged to 62 species of 46 genera in 16 families, in cluding 27 drought-resistant germplasm,4 salt-tolerant germplasm and 14 high resistant rust germplasm. In this study, local situation, growth, and decline conditions of crop germplasm resources were analyzed. Besides, the botanical classification and utilization importance of crop germplasm resources were estimated. Furthermore, the conservation, development, and utilization of crop germplasm resources in coastal areas of arid region of Gansu province were also discussed in the paper.
