Upland cotton (Gossypium hirsutum L.) is a naturally occurring photoperiod-sensitive perennial plant species. However, sensitivity to the day length was lost during domestication. The phosphatidylethanolamine-binding protein (PEBP) gene family, of which three subclades have been identified in angiosperms, functions to promote and suppress flowering in photoperiod pathway. Recent evidence indica...

The harmonic mean of the relative performance of genotypic predicted value (HMRPGV) method has been used to measure the genotypic stability and adaptability of various crops. However, its use in cotton is still restricted. This study aimed to use mixed models to select cotton genotypes that simultaneously result in longer fiber length, higher fiber yield, and phenotypic stability in both of the...

Thirteen genotypes of cotton developed through hybridization and mutation breeding techniques were evaluated during two consecutives years 2002-03-04 on eight locations covering most of the area of Punjab province including Faisalabad, Toba Tek Singh and Jhang. The eight sets of experiments were conducted in the naturally highly saline sodic soils, EC ranges from 7.8-36.1 d/Sm, pH=8.1-8.8, SAR=...

in order to study of water deficit effects on yield and some vegetative aspects of cotton, 30 cotton genotypes evaluated in 2014 summer at garmsar agricultural research station in greenhouse and field conditions. the experimental design was split plot based on a completely randomized blocks with three replications. six superior genotypes including k8801, k8802, avengard, varamin, khordad and qu...

difficult to prove cause and effect for maturity differences being responsible for any variation in response Potassium deficiency in cotton (Gossypium hirsutum L.) depresses among genotypes to K. Theoretically, differences in root yield by decreasing late season growth and is reportedly more harmful to early maturing cotton genotypes. Research objectives were to detersystem size or effectivenes...

Cotton is a well-known agricultural and industrial crop that plays significant role in Pakistan's economy. For this study, RCBD (Randomized Complete Block Design) using three replications was carried out to sow fifty different cotton genotypes. Results of the experiments showed under normal drought conditions, relative water content has highly positive association with excise leaf while at geno...

cotton is of particular importance  in fiber crops. variation in the cultivars and the potential of different cultivars is an important step in increasing production per unit area. in this study, nine new varieties of cotton including cotton hybrids successful and successful genotypes in a randomized complete block design with four replications,  with varamin camecial cultivar were evaluated in...

The problem of byssinosis has plagued cotton textile mills for hundreds of years, and it is still a problem today. With the regulations on airborne raw cotton dust set by OSHA and the ACGIH, research regarding the measurement of cotton dust in lint fiber is a necessity. A procedure known as the mass concentration particle size distribution (MCPSD) technique, developed at Texas A&M University, w...
