在今年3月底,南京市科委和南京科技与产业发展促进会联合举办的南京科技成果展览厅内,有一张极普通的女科技人员的工作照,这是南京农业大学沈又佳副教授在室内做杂交稻种子纯度检测试验的照片。这位1960年毕业于山东农学院农学专业的老教师,怎么会与种子纯度的检测结下不解之缘的呢?这还得从杂交稻的诞生说起。八十年代初期,杂交水稻种子纯度的检测,主要依赖海南种植鉴定,但此法费时费力,且不能及时满足大田用种的需要,常常是种子已经销出去了,鉴定结果还
At the end of March this year, Nanjing Scientific and Technological Achievements Exhibition Hall jointly organized by Nanjing Science and Technology Commission and Nanjing Science and Industry Association for Promotion of Development of Science and Technology has a working photo of a very ordinary female scientific and technical personnel. This is an associate professor Shen Youjia at Nanjing Agricultural University doing hybrid indoors Photo of rice seed purity test. The old teacher who graduated from agronomy of Shandong Agricultural College in 1960, how can he get along with the detection of the purity of seeds? This has to start with the birth of hybrid rice. In the early 1980s, the detection of the purity of hybrid rice seeds mainly relied on the identification of Hainan planting. However, this method was time-consuming and labor-intensive, and could not meet the needs of field planting in time. Often the seeds were sold out,
