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
