摘要：
A dark green dwarf mutant, TGM 167, was isolated from a gamma ray + sodium azide mutagenised population of cultivated groundnut breeding line, TFDRG 5. The mutant had a 45.8% reduction in height due to its shorter internodal length. Further, it was found to be insensitive towards exogenous GA3 application, although it had nearly the same level of endogenous GA3 as the parent. Genetic analysis revealed that the dwarfism is under the control of a single dominant gene. This dominant dwarfing gene was mapped with an SSR marker TC3H02 at a distance of 9.7 cM.
