Abstract:

Our objective was to evaluate G. hirsutum cotton lines, which includes indigenous, exotic collection, released varieties and lines developed from different breeding strategies were evaluated in alpha lattice designs with two replications along with five standard G. hirsutum check varieties viz., Sahana, Surabhi, MCU 5, DS 28 and ARBH 813 for yield and fibre quality traits. The analysis of variance revealed the presence of significant differences among genotypes and recorded wide range of variations for all the characters over environments. EC296596 (2263 Kg/ha), 128333-Acala-44 (2258 Kg/ha) and 543416A03N132 (2250 Kg/ha) recorded significantly higher seed cotton yield than superior check, ARBH 813 (1894 Kg/ha). CPD-420, FQT-38, CPD-2011, AKA-8828, DRC-305 and CPD-443 recorded higher ginning outturn (>38 percent) with high boll weight (>4.0g), more bolls (>15.0) and more fruiting points (>35). HAG-1055, HLS-321729, AK-23B, 543416A03N132, 126663, FQT-38 and 54335402A015 recorded high seed index with ginning outturn (>37 percent), boll weight (4.0g), more bolls (>14.0) and fruiting points (>35.0), moderate height (>95 cm to 105 cm). Five germplasm lines viz., FQT-21 (31.8 mm), IC356874 (30.9 mm), ADB-39 (30.9 mm), CPD-437 (30.0 mm) and EC559012 (30.0 mm) with higher fiber strength (23.2 to 24.7 g/tex) and on par with ARBH 813 for seed cotton yield (1555 to 1966 Kg/ha). These germplasm collections represent a valuable resource for improving seed cotton yield and fiber quality in cotton.
