作物种质资源品质性状鉴定评价现状与展望

Current Situation and Prospect of Identification and Evaluation of Quality Traits in Crop Germplasm Resources

作物种质资源品质性状鉴定评价是作物种质资源研究的重要方面,是深入挖掘、广泛利用作物种质资源的基础。本文对近年来作物种质资源品质性状鉴定评价情况进行了回顾,总结了鉴定评价工作取得的主要进展:完成了近20万份的作物种质资源(约占保存总数的50%)主要营养品质性状的初步鉴定评价;作物种质资源品质鉴定评价内容涉及面广、鉴定的品质性状变异性大、多样性丰富;提高了作物种质资源品质性状鉴定评价标准化程度。此外还介绍了国际上有关品质性状鉴定的发展趋势,并对未来国内作物种质资源品质性状鉴定评价提出了意见和建议。

Identification and evaluation of quality traits is an important part of crop germplasm resource research. It is the foundation of crop germplasm resource deep excavation and wide use. This article reviewed the research in identification and evaluation of quality traits for the past few years. The progress in China was summarized as main nutritional quality traits of 200000 accessions （about 50% of saved） had been evaluated preliminarily, contents of identification and evaluation involved widely and results were rich in variety and diversity, and the standardization level of the identification and evaluation increased. The international development trend was also introduced. At last, the opinons and suggestions in development of domestic crop germplasm resources quality identification and evaluation were put forward.
