Abstract

Sorghum is a multipurpose crop being used as food, feed, fodder and fuel. The objective of the study was to investigate breeding values of new F1 forage sorghum hybrids using line x tester crossing of six A1 cytoplasm type male sterile lines with five fertile local inbred lines and varieties, and 30 F1 hybrids were produced. Both parental lines and their F1 hybrids were field-evaluated for yield and quality traits for two successive years.  On the basis of two year hybrids evaluation programme, the lines, 637 A and 753 A were good general combiners for fodder yield and related traits and the lines 467A was found good general combiner for total soluble solids TSS. The testers HJ 541 and IS 2389 were found good general combiners for various yield traits and TSS. On the basis of specific combining ability, the crosses 467A X 2389, 725A X 308, 2219A X G46 and 2219A X HJ 541 were found to be promising for yield related traits. The crosses 467A X 2389, 637AX HJ 541, 637A X HC 308 exhibited good standard heterosis for fodder yield and related traits and the crosses 9A X 2389, 725A X 2389 and 753A X 2389 for TSS. On the basis of above study 467A X 2389 hybrid was found to be promising for fodder yield and related traits
