Inheritance and allelic study of brown midrib trait in pearl millet
Article Abstract:
There are two brown midrib lines in pearl millet, one developed through germplasm accession selection and the other through chemical mutagenesis. Forage value of the plants are restricted by lignin content with lower lignin content increasing the digestibility of the pearl millet. The brown midrib lines have lower lignin content than normal midrib lines. Cross breeding demonstrates that the brown midrib gene is a major recessive gene that is only dominant when two brown midrib lines are crossbred, indicating that the two brown midrib lines are allelic.

Narrow leaf mutant: a new plant type in pearl millet
Article Abstract:
A natural narrow leaf mutant in pearl millet was discovered in a landrace accession IP 8443 from Niger that looks similar to a grass plant and has a earlier flowering period with smaller seeds and spikes. Two narrow leaf mutants were located in a range of 78 plants. The plants have narrow leaf margins and thick stems. The leaves became broader when the mutants were cross bred with normal pearl millet but remained narrow when interbred, indicating a recessive gene. Further observation may help establish linkage groups.

A recessive homeotic mutant in pearl millet
Article Abstract:
A single recessive allele, phm, controls the phylloid homeotic mutant in pearl millet. Pearl millet expresses a homeotic mutant in fields and greenhouse environments. The expression of the mutant phenotype is higher in apical regions of the panicle. The mutation transforms the perfect floret into vegetative leaves with a meristematic region while the imperfect male is unaffected. The homeotic mutant is useful as a marker in floral morphogenesis and linkage studies.
