Semi-dwarf plant; possible allelism with bv2. Redesignation as bv2 was proposed by Singleton (MNL 28:11) but this is not used; relationship to bv2 of Piovarci (not in Stock Center) needs to be clarified. Genetic 2005 1 coordinates determined from these recombination and map data: bnl7.25 - (rd1 -0- npi238) - bnl8.29a; see MaizeGDB ID:61326. This gene was originally curated in MaizeGDB Database and the map position was displayed on the maize bins map if feasible.
