Purpose of Description

ICGL 6 has distinctive leaf characteristics. Most of its leaves are puckered (partially crinkled) with a yellow stripe along their margins. A few of the older leaves are phenotypically normal. Variants such as ICGL 6 are useful markers in genetic studies.

Origin and Development

ICGL 6 was isolated from a normal-leaved groundnut genotype OG 66-6-1 belonging to Arachis hypogaea subsp. fastigiata var. vulgaris. A single plant with abnormally puckered leaves was observed in a population of OG 66-6-1 grown in the 1979/80 postrainy season at ICRISAT Center. The plant was harvested and progeny rowed. Subsequently plants with puckered leaves were reselected in successive selfed generations, until their leaf phenotypewas stabilized.
