Abstract

                                Combining ability analysis was conducted in a line X tester model with seven lines and four testers for yield characters (seed cotton yield) and fibre characters (ginning outturn, seed index, lint index and mean halo length). The seven lines belong to G. hirsutum but differ in fuzz grades ranging from full fuzz to sparsely fuzz and a naked one. The fuzzed lines (TCH.104/1, TCH 70/7) and the tester LRA 5166 are good combiners for seed cotton yield. The sparsely fuzzed lines (TCH 65/8) and naked line (TCH 89/7) are good combiners for ginning out turn. The sparsely fuzzed line TCH 96/6 and the testers MCU 5 and MCU 9 are good combiners for seed index. The sparsely fuzzed line TCH 65/8 and the testers MCU 9 and LRA 5166 are good combiners for lint index. The naked line TCH 89/7 and the testers MCU 5 and MCU 9 are good combiners for mean halo length
