Summary
A brief description ofS. halepense and its relationship to the cultivated sorghums is given. The formation of rhizomes has been described. The inheritance of a few characters has also been recorded. Purple colour in the stigma is a monogenic dominant over the non-pigmented condition (yellow). Reduced filament is a simple recessive to the normal. The compact panicle was found to behave as a monogenic recessive to the loose paniele. Stray cases of extra-fertility of spikelets and ovaries with triple stigmas have been found to occur.
