Kodo 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.

Pattern of growth and tillering attitude is recorded at flowering.
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 dough stage.
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.
The number of leaves on main stem at flowering stage. Five randomly selected competitive plants are used for taking observation.
Leaf erectness is recorded at dough stage during rainy season.
Expose of middle internodes on main stem at dough stage is recorded during rainy season.
Length of the main tiller’s flag leaf at first primary axis node is measured at flowering stage. Five randomly selected competitive plants are used for taking.
Measured at widest point of flag leaf at first primary axis node at flowering stage. Five randomly selected competitive plants are used for taking observation.
Measured from internode to ligule of flag leaf at first primary axis node. Five randomly selected competitive plants are used for taking observation.
Measured from node of lowest raceme (thumb) to tip of last raceme. Five randomly selected competitive plants are used for taking observation.
Measured from primary axis node to inflorescence base node (secondary node) at maturity. Five randomly selected competitive plants are used for taking observation.
Development of flag leaf at second axis node (Figure 2) at dough stage is recorded.
Number of racemes above first (lowest) primary axis node at dough stage. Five randomly selected competitive plants are used for taking observation.
Overall agronomic desirability of the accession is observed visually at maturity.
Weight of freshly harvested 100 seed measured at about 12% moisture content.
Length of the basal raceme at the first primary axis node measured at dough stage. Five randomly selected competitive plants are used for taking observation.
Length of the longest raceme on main inflorescence excluding thumb is measured at dough stage. Five randomly selected competitive plants are used for taking observation.
