Dear Ines,

for wheat the cultivar file WHCER40.cul located in the genotype folder
contains the neccessary information:

/They can be calculated (approximately) from
! V3.5 coefficients as follows:
!
! P1V   = P1V(v3.5)*10
! P1D   = P1D(V3.5)*20
! P5    = P5(V3.5)*20 + 430
! G1    = G1(V3.5)*5 + 5
! G2    = (G2(V3.5)*0.35+0.65) * P5/20
! G3    = G3(V3.5)*0.7
! PHINT = PHINT(V3.5)

/Greetings Jans
