Abstract: Initial evaluation of twenty two G. hirsutum genotypes with three checks were screened for yield, and fibre quality in randomized block design under rainfed condition at Cotton Research Station, Nanded during 2015-16. The entries were sown in three replications with two rows having spacing 60 x 30 cm and 6 metres each row. Results were statistically significant for seed cotton yield. As many as four entries viz. BGDS 1033 (1478 kg/ha), ARBH 1551 (1369 kg/ha), NDLH 2028-2 (1370 kg/ha) and NDLH 2005-4 (1529 kg/ha) recorded significant superiority for seed cotton yield over higher yielding check, NH 545 (1044 kg/ha). Lowest yield was recorded by strain H 1464 (581 kg/ha). Ginning outturn was ranged from 29.78 (ARBH 1551) to 41.19 (CCH 15-3). Only three strains viz., CNH 07-16 (38.23 %), CCH 15-3 (41.19 %) and BGDS 1055 (38.52 %) recorded ginning outturn above 38 per cent. The higher yielding strain NDLH 2005-4 recorded medium ginning outturn (35.18 %). Upper half mean length (UHML) of the genotypes under testing was ranged from 24.4 mm (GBHV 198) to 29.2 (NDLD 2005-4), Micronaire (ug/inch) was ranged from 3.3 ug /inch (NH 615) to 4.9 ug/inch (RAH 1271). None of the strains recorded better bundle strength (g/tex) than quality check, Suraj (32.6 g/tex). However, three strains viz., CCH 15-3 (30.8 g/tex), CNH 1122 (31.3 g/tex) and CCH 15-4 (32.2 g/tex) recorded fibre strength above 30 g/tex. In general, performance of strain NDLH 2005-4 was found excellent for seed cotton yield (1529 kg/ha), lint yield (535 kg/ha) with medium ginning outturn (35.18 %) and better fibre properties (29.2 UHML (mm), 4.1 micronaire (ug/inch) and acceptable bundle strength (26.2 g/tex).
