Abstract
In vitro pollen germination of five species (Brassica oleracea, B. campestris, B. hirta [Sinapis alba], B. napus and B. carinata) and two interspecific hybrids from the genus Brassica was tested in four media. Genetically fixed differences were found among species in the requirements for optimal pollen germination. The experiments were designed to define optimal medium contents of mineral salts, sugar and PEG for each of the investigated species or hybrids. The differences found among species are discussed in relation to the evolutionary trend.
