Plant grows to maturity but lacks root support and lodges badly. (E. Khavkin). Genetic 2005 3 coordinates determined from these recombination and map data: rt1 -8- rg1 -33- lg2 -30- a1; see MaizeGDB ID:935364. This gene was originally curated in MaizeGDB Database and the map position was displayed on the maize bins map if feasible.
