Proso 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 during rainy season.
Measured from ground level to tip of inflorescence (ear) of the main tiller of five randomly selected competitive plants at the dough stage.
Pattern of growth and tillering attitude is recorded at flowering.
Count the number of tillers including main stem at dough stage. Five randomly selected competitive plants are used for taking observation.
Number of culm branches on the main stem at maturity is recorded.
Presence pubescence on leaf sheath of main stem at dough stage is recorded.
Presence of pubescence on ligule of main stem at dough stage is recorded.
Presence of pubescence on 3rd or 4th leaf from top of main tiller at dough stage is recorded.
Length of the main tiller’s flag leaf from ligule to tip is measured at flowering stage. Five randomly selected competitive plants are used for taking observation.
Widest point of the main tiller’s flag leaf is measured at flowering stage. Five randomly selected competitive plants are used for taking observation.
Measured from main tiller’s node to ligule of flag leaf from top at flowering stage. Five randomly selected competitive plants are used for taking observation.
Measured from top most node to base of the inflorescence at dough stage. Five randomly selected competitive plants are used for taking observation.
Distance between ligule of the flag leaf and base of the inflorescence on the main tiller is measured at dough stage. Five randomly selected competitive plants are used for taking observation.
Measured from lowest branch to tip of last branch of inflorescence at dough stage. Five randomly selected competitive plants are used for taking observation.
Count the number of nodes present on the main stem at maturity and mean of five randomly selected plants is recorded
Count the number of primary branches on main axis of inflorescence at maturity and mean of five randomly selected plants is recorded.
Counted as number of major branches on primary branches of inflorescence is recorded at maturity.
Shape of the inflorescence is recorded at maturity.
Race
