In 2004-2005, at the Plant Breeding and Acclimatization Institute, Research Division at Młochów, the usefulness of two 2n pollen-producing diploid clones DG.93-332 and DW.96-1025 were assessed - using interploid Ax-2x hybridization - to develop the tetraploid breeding material of cold chipping type. Both diploid parental forms are complex hybrids; they are possessing in their pedigree, besides dihaploids of Solanum tuberosum, the following species: S. acaule, S. chacoense, S. demissum, S. gourlayi, S. yungasense and the clone DW.96-1025 additionally also S. phureja species. The key characters of both paternal forms DG.93-332 and DW.96-1025 are: cold chipping ability and resistance to PVY and Synchytrium endobioticum. The additional valuable traits of DG.93-332 are very low enzymatic browning, lack of after cooking blackening and resistance to PLRV and PVX. The progenies originating from crosses between diploid paternal forms (DG.93-332, DW.96-1025) and the set of five tetraploid maternal forms were evaluated for tuber yield, mean tuber weight, depth of eyes (buds), the incidence of external and internal tuber defects and chip colour after cold storage (4-6°C). Each cross was represented by 60 unselected seedlings grown on the non-irrigated field in 2004. Out of two tested diploid parents, the clone DG.93-332 was more suitable for generation of valuable tetraploid progeny. The half sib family of the DG.93-332 in comparison with the half sib family of the clone DW.96-1025, was characterized on average by: higher tuber yield, higher mean tuber weight, more light-coloured chips after cold storage at 4-6°C. The frequency of cold chipping clones and the level of agronomic and resistance (PVY, PLRV) traits above target values in 4x-2x half sib family of the DG.93-332 was 24.1%, while in the 4x-4x progenies of tetraploid parents with high breeding value for chip colour ranged from 5 to 18.6%.
