Title	Interaction of barley mutants Hooded and tweaky spike in F SUB 1 hybrids
Journal	Biologija
Year	2004
Pages	13-20
Author	Vaitkuniene V Varnaite A Rancelis V
Abstract	The Hooded mutation of the barley gene BKn3 causes ectopic development of additional flower instead of awn or on awn. Another barley developmental mutation, tweaky spike ( tw ), causes ectopic conversion of lodicules to stamens and/or carpels. The interaction of both mutations was investigated on 15 different Hooded type genotypes in F SUB 1 (heterozygous state). The borderline between the action of both mutant genes is well expressed: tw acts on basic flower whereas the Hooded type mutants determine additional flower. The latter mutant gene does not display any effect on the basic flower, while tw shows a significant influence on the development of additional structures on the lemma/awn border. The effect depends on the type of Hooded mutation
