ABSTRACT
Yield and fibre quality performance of DNH-105 strain in comparison with standard cotton varieties (CIM-573, CRIS-342, Gomal-93, NIAB-112 and CIM-612) was assessed at Cotton Research Station, D.I. Khan, Pakistan, during growth season 2011‑2013 in a randomized complete block design replicated thrice. The strain DNH-105 gave optimum yield owing to more bolls per plant (37.2), boll weight (3.4 g) plus higher ginning out turn (39.9%) compared to the standard varieties of cotton in Pakistan. The quality characteristics such as fibre length (29.2 mm), strength (28.5 g tex-1), micronaire (4.3µg inch–1) and uniformity (80.2%) were also higher for DNH-105 than other varieties. Ginning out turn ranged from 37.2 (CIM-612) to 39.9% (DNH-105). Fibre length ranged from a low of 28.3 (CIM-612) to a high of 29.2 mm (DNH-105) while fibre strength was observed 25.0 (CIM-612) to 28.5 (DNH‑105) g tex-1. Micronaire value ranged from 4.3 (DNH-105) to 4.8 µg inch–1 (CIM-612). Fibre uniformity ranged from a low of 77.1 (CIM-612) to a high of 80.2% (DNH-105). It is concluded that strain DNH-105 has high yield potential and best suited to ago-climatic conditions of Dera Ismail Khan, Pakistan as compared to the other varieties of cotton.
