Description A set of 116 pearl millet hybrid parents was evaluated in two summer seasons for 30 forage
specific morphological and quality traits. Green forage yield (GFY) ranged from 15.0 to 29.0 t/ha at first
cut and 12.0 to 42.0 t/ha at second cut, while the dry forage yield (DFY) ranged from 3.0 to 6.0 t/ha
at first cut and 5.0 to 9.0 t/ha at second cut. Important forage quality traits like stover nitrogen varied
from 1.84 to 2.34% at first cut and 1.77 to 2.00% at second cut, while metabolizable energy (ME) ranged
from 7.42 to 7.76 MJ/kg at first cut and 6.95 to 7.68 MJ/kg at second cut. In vitro organic matter
digestibility (IVOMD) varied from 54.0 to 56.0% at first cut and 51.0 to 55.0% at second cut. Pollinator
parents showed higher mean values for most of the forage traits than the seed parents. Small but
significant negative correlation was found between crude protein (CP), IVOMD and DFY indicating that
modifications are needed to breed for higher forage biomass coupled with better forage quality traits.
Hierarchical cluster analysis based on forage specific morphological and quality traits delineated 116 pearl
millet hybrid parents into 6 distinct clusters. This evaluation identified clusters of hybrid parents having
high mean values for specific promising forage quality traits, this information can be used for developing
promising forage-type hybrids in pearl millet.
