Abstract:
Sorghum is a cereal crop that can grow in diverse environments and has many nutritional benefits. Analysing the protein and fiber content of the sorghum genotypes can help breeders to develop improved varieties with improved nutritional quality. This study was conducted to evaluate the yield contributing traits and to profile the protein and fiber content of three red sorghum crosses viz., Paiyur 2 X PYR RS.16.07, Paiyur 2 X Kottathur local-5, Paiyur 2 X Ammapatti local-1 along with their parents. In this study, the Kjeldahl method was employed to analyse the total crude protein content whereas, the crude fiber was estimated using the standard procedure. Results indicated that the parent Kottathur local 5 and its cross Paiyur 2 X Kottathur local-5 had a significant protein as well as fiber content in comparison with that of other parents and their crosses. It was followed by the cross Paiyur 2 X Ammapatti local-1which had the next best protein and fiber content. All the crosses were high-yielding in nature. As a whole, the cross Paiyur 2 X Kottathur local-5 surpassed all other crosses and parents in terms of seed yield, protein and fiber content.
