Pearl millet Characterization
The characterization of germplasm is essential for its effective use in crop improvement. Phenotypic characterization involves recording traits that are highly heritable, easily observable, and consistently expressed across different environments. The ICRISAT germplasm accessions are characterized at the Patancheru location in India (Latitude: 17.51° N, Longitude: 78.27° E, Altitude: 545 m). The descriptors developed for characterization and preliminary evaluation are followed for each crop assessed. Detailed crop-specific characterization information can be found in the ICRISAT Genebank Technical Manual manual.

Number of days from first irrigation after sowing to when 50% of plants flower in an accession is recorded as days to 50% flowering. Stigma emergence on the main tiller panicle is considered as flowering
Number of days from first irrigation after sowing to when 50% of plants flower in an accession is recorded as days to 50% flowering. Stigma emergence on the main tiller panicle is considered as flowering.
Measured from ground level to the tip of the panicle of the main tiller. Five randomly selected competitive plants are used for taking observation.
Measured from ground level to the tip of the panicle of the main tiller. Five randomly selected competitive plants are used for taking observation.
Count the number of basal tillers including main tiller at dough stage. Five randomly selected competitive plants are used for taking observation.
Count the number of basal tillers, which bear seeds in panicles at dough stage. Tillers having panicles younger than dough stage are not considered. Five randomly selected competitive plants are used for taking observation.
Distance between ligule of the flag leaf and base of the panicle on the main tiller is noted at dough stage. Majority of the accessions have positive exertion (panicle fully exserted above the ligule of the flag leaf), while some show negative exertion (panicle not fully exserted from the flag leaf but some portion is enclosed within the flag leaf). Five randomly selected competitive plants are used for taking observation.
Uniformity for panicle maturity is visually recorded at maturity stage.
Measured from base to tip of the panicle on the main tiller at dough stage. Five randomly selected competitive plants are used for taking observation.

Panicle shape is visually recorded at dough stage.
The density of spikelet's in a panicle also referred as compactness of panicle is visually recorded at maturity stage as
Bristle length is visually recorded at dough stage.
Color of freshly harvested seeds is visually recorded after threshing.
Weight of 1000 seeds recorded at about 12% moisture content.
The seed endosperm texture is visually scored.
Green fodder yield potential is recorded at flowering stage using visual score.
Seed yield potential of the accession is visually scored (1-9 scale) by considering panicle number, size and density, seed number and size.
Overall plant aspect of the accession is visually scored by considering the overall agronomic features, seed yield, and fodder yield potential.
