Evaluation of American cotton genotypes for yield and yield contributing parameters

Abstract

The experiment was laid out in a Randomised block design with three replications. There were twenty seven hirsutum genotypes of cotton namely AKH-8660, AKH-31, AKH-073,AKH-976, AK-32, AKH-2006-2, AKH-09-5, AKH-10-2, AKH-10-3, AKH-10-10, AKH-2012-8, AKH-2012-9, AKH-2013-1,AKH-2013-2,AKH-2013-3, AKH-1301,AKH-1302, AKH-1303, CNHO-12, GV-22, IC-358555,IC-357342,IC-359088,AKH-081,AKH-9916,PKV-Rajat and AKH-8828 were applied. The gross plot size was 1.8 ×6 m2. The yield parameters like no. of monopodia, no. of sympodia, no. of bolls per plant, boll wt.(g),Seed cotton yield(g/plant), Lint yield (g/plant),Ginning % and seed index (g) were influenced significantly by genotypes. Genotype AKH-1303 recorded significantly higher no. of sympodia (15.73), no. of bolls per plant (16.47/plant), seed cotton yield (62.89 g/plant), Lint yield (22.19 g/plant) and seed index (10.35g).
