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。
The survey collected the anti-counterculture crops germplasm resources in arid areas of Gansu Province and provided the basic materials for the protection, research and utilization of the anti-counterculture crop germplasm resources in Gansu Province. From 2011 to 2013, the author analyzed the germplasm resources of the anti-counterculture crops distributed in 18 counties (cities, districts), 48 townships (towns) and 81 administrative villages in the arid region of Gansu by means of consulting literature, interview and field investigation. The status of conservation and utilization were investigated and germplasm was collected. A total of 845 grain crops, cash crops, vegetables and wild resources were collected, belonging to 62 families, 46 genera and 62 species, including 27 drought-resistant germplasm resources, 4 salt-tolerant germplasm resources and 14 high-rust-resistant germplasm resources. In this paper, we analyzed the status quo, growth and decline of the germplasm resources in the region, their causes and investigation, the types of the collected resources and their utilization value, and the protection, development and utilization of the anti-countercurrent crop germplasm resources in the arid region of Gansu Province Discussed.
