Close co-operation with the N.I.A.B., D.A.R.D., plant breeders and in particular the S.A.C., help us identify the best varieties. CASTLE MIXTURES only contain S.A.C. first choice varieties.
As independent seed specialists, we are free to select only those varieties which we feel are most appropriate for use in our CASTLE MIXTURES.
A number of leading seed merchants are now controlled by multinational
breeders who may influence mixture composition.
