The rate of late blight disease was analysed for individuals of a diploid Solanum phureja–Solanum tuberosum dihaploid hybrid population (PD), using three different assessment techniques, in the laboratory, screenhouse, and field. These hybrids expr

Frequencies of floral morphs in progenies obtained from a complete set of diallelic crosses among three accessions of tristylous, octoploid oca (Oxalis tuberosa) were used for a Mendelian analysis of floral morph inheritance. The frequencies observed

Long-, mid-, and short-styled clonal accessions of oca (Oxalis tuberosa) were intercrossed in a complete diallelic design. Pollen tube growth in styles was monitored in all diallelic crosses. Pollen fertility was estimated by two tests: staining of p

Progenies from eight tetraploid potato crosses were assessed for the association between ineffective R-genes and lesion expansion rate (LER) in mm per day on detached leaves that had been inoculated with Phytophthora infestans. In two of the progenie

Eleven progenies, ten bi-parental and one selfed, of tetraploid potato were assessed for phenotypic segregation ratios of resistance to susceptible individuals against two isolates of P. infestans, one avirulent to all 11 known potato R genes (avirul

Results of testcrosses and seed set data of the dihaploid breeding program at the Potato Research Institute in Gross Lusewitz, Germany, indicate that the low level of female fertility could hinder success in crossing work. With the objective to revea

Pollen tube growth was investigated in a diallelic crossing design with seven genotypes of the diploid wild potato species Solanum commersonii, accession O/S UR-9, CIP 762459. Pollen tube growth in the style was recorded using a combined quantitative

Pollen tube growth was evaluated using an 18-step scale after both intra- and interspecific pollinations of genotypically widely differing diploid potato species and potato dihaploids expressing monofactorial gametophytic incompatibility. The results
