The ginning outturn is the most important trait to decide the lint yield. The lower ginning outturn is the reason for lower lint yield in the zone and need immediate attention. 3954 geographically and phenotypically diverse lines of G. hirsutum were screened during 2013-14 to 2015-16 for 3 years for ginning outturn, seed cotton yield and yield contributing traits. A wide range of variability for ginning outturn from 21.7 - 42.0 percent, yield/plant 50.4 -129.8g, number of monopodia 0-13, number of sympodia 0-23, number of bolls/plant 5-47, incidence of CLCuD 0-100 percent were observed in the germplasm. Among the 100 accessions with ginning outturn above 40 percent, the accessions IC 359065 (42), SA 1006 (42), IC 359429 (42), IC 359660 (42) and IC 359383 (42) were observed superior. Among these, the superior accession for yield/plant were IC 359383 (129.2g), IC 359429, for boll number IC 359383 (44), IC 357487 (31), IC 359660 (26), for boll weight SA 1006 (3.58g), IC 359706 (3.5g), IC 359660 (3.5g), for number of monopodia SA 1006 (9), IC 359383 (4), IC 357487 (3); for number of sympodia IC 359429 (15) IC359383 (14), IC 359227 (11) and for tolerance to CLCuD IC 357726, IC 358479, IC 357856 were observed . These can be used for crop improvement programs.
