Abstract
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.
