Abstract

The present study was conducted at the Cotton Research Institute (CRI) in Tandojam during the kharif season of 2022. The study aimed to investigate the yield and fiber characteristics of upland cotton (Gossypium hirsutum L.) genotypes. The plant material was grown in the field in a randomized complete block design (RCBD) with three replications and eight genotypes, including one check variety. The plant height (cm), sympodial branches per plant, bolls per plant, boll weight, and staple length showed highly significant differences at a probability level of <0.01. Monopodial branches per plant, seed cotton yield, and GOT% indicated differences at a probability level of >0.05. Among the eight genotypes, the TH-26/23 genotype had the maximum plant height, monopodial branches per plant, boll weight, seed cotton yield, while TH-23/23 had the maximum sympodial branches per plant, bolls per plant, seed cotton yield, and GOT%. According to the correlation analysis, plant height showed a significant favorable relationship with monopodial branches per plant, and a highly significant and favorable relationship with boll weight, seed cotton yield, and GOT%. Monopodial branches per plant showed a highly significant relationship with GOT%. Sympodial branches per plant showed a significant relationship with staple length. Boll weight showed a highly significant correlation with seed cotton yield.
