SiriusWheat1:
Developed by Crop Research Division (CRD), DSIR, Lincoln College, and ARD, MAF, Lincoln, New Zealand. Written in FORTRAN77 by Peter D. Jamieson (PDJ), CRD, DSIR, Lincoln. Commenced May 1985. Consulting: J.N. Gallagher, D.R. Wilson, and J. Reid.
SiriusWheat version 2:
Written by PDJ, New Zealand Institute for Crop & Food Research (CFR), in cooperation with Ian Brooking, New Zealand Institute of Horticulture and Food Research, John R. Porter (JRP), the Royal Veterinary and Agricultural University, Denmark, Mikhail A. Semenov (MAS), Long Ashton Research Station (LARS), IAFR, England. Conversion to C language by Galina Romantchikova (GR) in June 1993. Modification to deal with new phenology based on the prediction of final leaf number, commenced June 1993 at LARS by PDJ and MAS. Modification to vernalization completed in April 1995 at CFR by PDJ and MAS.
SiriusWheat version 3:
SiriusWheat version 3 includes a new water balance sub-model, based on a simplified version of T.M. Addiscott leaching model and a nitrogen balance, based on a simplified version of NITCROS (DAISY) Model. Written by MAS and PDJ at LARS in June 1994 and completed at CFR in May 1995. Windows front end written by GR in May 1996.
SiriusV99:
SiriusV99 includes a new procedure for crop nitrogen uptake from the soil and a new procedure for redistribution of nitrogen to the grain. Written by PDJ and MAS at CFR in January 1999.
Sirius2000:
Sirius2000 is a new implementation of SiriusV99 in C++ allowing incorporation of multi-year runs and multi-crop competition. Completed at LARS in July 2000 by MAS and PDJ. information on the lattest version of Sirius can be found here.
Sirius revision:
Sirius revision is an attempt to isolate the siriusV99 models into unique modules for extended use. Code completed at CFR in May 2001 by Robert F. Zyskowski.
SiriusQuality:
SiriusQuality includes a new procedure for grain nitrogen and dry matter accumulations, and partitioning of grain nitrogen into protein fractions and of grain dry matter into structural dry matter and starch. Procedure developed by Pierre Martre (PM), INRA, Clermont-Ferrand (INRA-CF), France, JRP, and PDJ. It is also an attempt to name and isolate the crop parameters into a parameter file (*.par). The windows front end includes a tab to perform sensitivity analyses of the crop varietal and non-varietal parameters. Code completed at CFR in April 2003 by PM, Stefan M Henton (CFR), and RFZ.
SiriusQuality1:
SiriusQuality1 includes a new leaf canopy layers model based on C. Lawless model and a simplification of ADEL-Wheat model linking leaf area and phenology and a new model for post-anthesis crop nitrogen uptake. It also includes an automatically generated documentation created using Doxygen V1.4.4 documentation system. Code completed at INRA-CF in May 2005 by PM and Yves Chambrin (INRA-CF), David Lelong (INRA-CF), MAS, PDJ, and RFZ. Consulting: B. Andrieu, INRA, Grignon, France.
SiriusQuality1.5:
SiriusQuality1.5 is a new implementation and refactoring of SiriusQuality1 in C#. It includes new procedures to model nitrogen and dry matter transfer at the phytomer level that takes into account the acclimation of leaf nitrogen to vertical light gradient. Soil water deficit and temperature response functions were also revised. An advanced graphical user interface was developed to facilitate the creation of complex multi-runs. Code completed in November 2009.
SiriusQuality2:
SiriusQuality2 includes a windows front end for the optimisation of crop and soil parameters with several metaheuristic optimization methods and objective functions. It also includes a revision of the daylength response in the phenology module to consider short-day vernalization. Code completed at INRA-CF, by PM, Yoann Gualtieri, and Malek Ben Salem, in September 2013.
