Investigation of dihaploid potatoes in the netherlands
Tóm tắt
Two hundred primary dihaploids (2n=2x=24) were obtained relatively easily from Dutch varieties and breeding stocks of the potato (2n=4x=48). Male fertility is rare in primary dihaploids but increases rapidly with further crossing. It is thus possible to inbreed and cross-breedSolanum tuberosum at the diploid level. Tetraploids were obtained by colchicine treatment. Tetraploids were also obtained by backerosses of dihaploids with tetraploids.
