Abstract

Abstract

A dynamic simulation model for rape phenological development is established according to rape physiological and ecological theories and the quantitative relationship between rape phenological development and the environmental factors. The "wheat clock model" in WCSODS and the vernalization model in CERES-wheat are used for reference. A three-year experimental data set is partially used for modification and determination of the genetic parameters for 2 cultivars and partially for validation of the model. The simulated errors are the compared with the accumulated temperature method. The results show that the average errors are within 1 day for different development period, and the standard errors are within 2 days for whole developmental duration.
