Conteúdo: 	Anther culture responsiveness of three H. spontaneum derived spring barley lines, RS170-47(A), RS20-1(B) and 1B-152B(C) was investigated using only one type of culture medium and treatment. The line 1B-152B was identified as highly responsive producing 22.4 total and 12.4 green regenerants per 100 anthers plated. 74% of these green regenerants were spontaneous double haploids. A genetic analysis involving F1 and F2 plants derived from crosses A × B and B × C revealed that the factor(s) determining high anther culture responsiveness in line 1B-152B was heritable and behaved as dominant in the F1. There was an indication that genotypic responsiveness in anther culture for green plant regeneration was different from total or albino plant regeneration.
