Abstract:

Trial, represented by regional crop variety performance test, is one of the most important bases to determine the species value and suitable extension areas  for crop variety. Large scale data are produced each year, but a mass of manual operation often causes input errors. In order to get reward in a short period of time, some breeders tamper with the data at times, making it difficult to protect the data quality. Further more, the traditional experimental data are managed and analyzed through Excel. It is unable to  correct and logically judge the data by big amount. This brings about a great deal of hidden danger to variety evaluation at late stage and accuracy of policy decision. In order to introduce a change, this paper adopts modern information processing means to develop a pre-processing system for crop varieties and their test data, so as to elliminate wrong or even false data with maximum. Thus, superior and reliable data can be provided for further experimental and varietal evaluation, analysis and decision making. This system is being run in trial at some large scale seed companies, such as Jinsenonghua and Beijing Denong. Good application results have been achieved.

Key words: crop varietal trial, pre-treatment of data, varietal evaluation
