Comment
Complementary dominant genes. Genotypes producing dwarfness: D1- D2- D3- d4d4, D1- D2D2 d3d3 d4d4, D1- d2d2 D3- D4-, D1- D2- d3d3 D4- and D1- d2d2 d3d3 D4D4. Evidence for multiple allelism is given in (1169).
Lists of genotypes can be found in 243, 377, 692. The effects of multiple allelism at D2 and possibly at D1. and modifying genes were demonstrated (1169).
Knott (491) described a lethal dwarf condition controlled by a dominant gene closely linked with Sr30 (chromosome 5D) in Webster and a complementary recessive gene in LMPG.
Phenotypes resembling grass clump dwarfs in hybrids carrying a 2BL.2RS translocation were reported by May and Appels (656). The complementary gene(s) in wheat was not D1, D2 or D3. The effect was suppressed at high temperature.
