ABSTRACT: An allelic sorghum
[Sorghum bicolor (L.) Moench] mutant with thick and narrow erect leaves (Thl)
and reduced adaxial stomatal density was isolated from the Annotated
Individually pedigreed Mutagenized Sorghum mutant library developed at the
Plant Stress and Germplasm Development Unit at Lubbock TX. The mutant, Thl, was
isolated from a pedigreed M3 family generated by ethyl methanesulfonate
mutagenization from an elite inbred sorghum line, BTx623, which had been used
to sequence the sorghum genome. The mutant has been backcrossed to the
wild-type BTx623 confirming that the trait results derive from a stable
recessive nuclear gene mutation. Herein, we briefly described morphological and
selected physiological characteristics of this mutant sorghum.
