Five cotton cultivars were crossed in a complete diallel to study the inheritance of different polygenic traits. Genotypic differences were found to be significant (P<0.01) for all the characters. Adequacy tests disclosed that data of all the parameters were fully adequate for genetic analysis except bolls per plant, staple length, fibre strength, and fibre fineness, which was partially or not ...

Five upland cotton cultivars were crossed in a complete diallel crossing system to investigate inheritance pattern and combining ability of parents for different fiber quality traits like staple length, fiber strength, fineness and uniformity. The study was carried out in the Department of Plant Breeding and Genetics, University of Agriculture, Faisalabad during the years 2005-07. Highly signif...

Interspecific and intraspecific hybrids show varying degrees of heterosis for yield and yield components. Yield-component traits have complex genetic relationships with each other. To determine the relationship of yield-component traits and fiber traits with seed cotton yield, six lines (Bt. CIM-599, CIM-573, MNH-786, CIM-554, BH-167, and GIZA-7) and three test lines (MNH-886, V4, and CIM-557) ...

Cotton is the most important commercial crop of India and heterosis in cotton is well documented with 7 to 50 per cent heterosis in interspecific (G. hirsutum x G. barbadense) hybrids, 10 to 138 per cent in intra-hirsutum hybrids and upto 220 per cent in desi (G. herbaceum x G. arboreum) hybrids. Currently hybrid cotton, especially Bt cotton hybrids, occupies more than 80 per cent of cultivated...

Staple yarns form the bulk of the manufacturing activity of the U.S. textile industry. Staple fiber yams are utilized in the making of apparel, upholstery and industrial fabrics. Yarns may be made from natural staple fibers or from a variety of synthetic fibers or from the blends of different fibers. As a matter of fact, blends constitute a bulk of the staple yarns manufactured in the U.S. Alth...

Textile materials made from natural fibers have played an important role in the life of human beings from time immemorial and still are widely used in the modern textiles industry for their unique properties as high quality tex tile materials. Due to the variation in staple length, the natural fibers with short staple length can’t be used to spin yarns. Consequently, natural fibers such as wool...
