Three Andean tetraploid potato genotypes (2n= 48) and 7 anther-derived dihaploids (2n=24) originating from two of the tetraploids were used in anther culture. Relative number of embryos/vial was significantly higher when the anther culture media was gelatinized with 3% potato starch than when Gelrit

โฆ Synopsis
Anthers of the Solanum tuberosum genotype H3703 were cultured on medium containing equimolar concentrations of sucrose or maltose. It was found that significantly more pollen embryos became plants after culture on maltose and hence the yield of plants per 100 anthers cultured increased significantly. Mechanisms by which carbohydrate source may influence response to anther culture are discussed.

The role of ethylene in embryogenesis of cultured potato anthers was studied indirectly by testing various substances known to affect ethylene formation. The reducing agents ascorbic acid and L-cysteine prevented browning of anther cultures and significantly stimulated embryogenesis. Embryogenesis w
