Variability of Grain-filling Traits in Early Maturing CIMMYT Tropical Maize Inbred LinesEGasuraauthorP SSetimelaauthorATarekegneauthorDIcishahayoauthorREdemaauthorP TGibsonauthorPOkoriauthorGrain-filling rate (GFR), effective grain-filling duration (EGFD) and total grain-filling duration (TGFD) are important physiological traits of maize (Zea mays L.) grain yeild (GY) formation. To devise effective breeding strategies, the genetic nature of these traits is pre-requisite for improvement in early maturing maize.Maize2013Crop Science Society of AmericaArticle
