| 1 | Production and genetic improvement of minor cereals in China显示文摘China is a leading country in the production of several minor cereals such as foxtail millet,Job's tears,naked oat,and naked barley.Sorghum and proso millet have also contributed greatly to Chinese agriculture.Foxtail millet,sorghum,barley,and proso millet were widely grown as major crops 60 years ago,and the reduction in their cultivation area reflects historical changes in Chinese agriculture over the past decades.Systematic germplasm collections from the 1950 s to the 1990 s gathered more than 66,690 accessions of these minor cereals,and for some of them,the Chinese germplasm collections are the largest in the world;for example,the 27,700 accessions of foxtail millet.Germplasm evaluations of each cereal species have focused mainly on drought tolerance,nutritional quality,and resistance to their main diseases.Comparisons among lines and selection of those with desirable traits were the main breeding methods for minor cereals in the 1950 s and 1960 s,but these methods were replaced by crossbreeding in the 1970 s.Newly developed cultivars have greatly changed the production situation,and many super cultivars have become milestones in crop breeding history.In this review,we describe the distribution and ecoregions,origin and domestication,and landmark varieties of several minor cereals in China.Nearly all of the minor cereals are drought-tolerant and fertilizer-efficient.The requirements for environmentally friendly crops and a more diverse food supply for humans and animals provide new opportunities to cultivate minor cereals in the drier and warmer environmental conditions that are predicted in the future. | Xianmin Diao | 2017 | The Crop Journal2017，5，2： | 38 |
| 2 | 玉米霜霉病对我国农业生产的潜在威胁及检疫对策显示文摘在玉米霜霉菌(Peronosclerosporaspp.)中,P.sorghi可随高粱种子(尤其是带颖壳的),P.philippinensis与P.sacchari可随甘蔗插条远距离传播。初步分析我国各地发病可能性为:黄淮平原零星发生,长江以南湿热地区发生可能性大,热带亚热带地区适于发病。应有针对性实施检疫,防止国内病菌蔓延及国外病菌传入,注意选育抗病品种。 | 王圆 吴品珊 | 1994 | 植物检疫1994，8，3： | 3 |
