CHEN Ding-shan1,CHENG Peng1,2,LI Dong-hui3,XIAO Lang-tao1,2(1.Hunan Provincial Key Laboratory of Phytohormones and Growth Development,Changsha 410128,China;2.Hunan Provincial Key Laboratory for Crop Germplasm Innovation and Utilization,Changsha 410128,China;3.College of Information Science and Technology,Hunan Agricultural University,Changsha 410128,China)  
Based on Chalkiness V1.0,using Visual C++.NET as tools,a computer image processing system ChalkinessV2.0 has been developed for the detection of chalky rice rate,chalkiness degree and grain shape for grading of the high quality rice required by the national standard NY147-88.The system is composed of modules of image preprocessing,sample identification,chalkiness distinguishing,ratio of length and width detection,statistics and analysis and results export.The system can analyze the rice chalkiness of three rice varieties: Fengyuan B,Miyang 46 and Nipponbare.Chalky scores such as chalky rice rate,chalkiness degree and projected area can be gotten with parameters imported only once.
