Dear Wendy,
The best option you have is to find out the cultivate whose
genetic coefficients are pre-determined,and having the same
phenological characteristics as DT84. Else if you have 3-4
years experimental data of Dt84 then also u can work out the
genetic coefficients using GenCal.
With bes regards
