Associations among Lint Yield, Yield Components, and Fiber Properties in an Introgressed Population of Cotton
Broadening the genetic base is essential for genetic improvement of lint yield and fi ber quality in upland cotton (Gossypium hirsutum L.). An exotic germplasm population derived from multiple crosses between G. barbadense L. and G. hirsutum was obtained from USDA-ARS at Las Cruces, NM. Experiments were designed to evaluate this germplasm for genotypic variation in lint yield and fi ber quality...
متن کاملAssessment of genetic variability, heritability and association of plant attributes with lint yield and fiber quality in advanced lines of cotton (Gossypium hirsutum L.)
Information on genetic variability and heritability of plant attributes and their correlation with lint yield and fiber quality is important for planning breeding and selection strategies for prediction of genetic gains in cotton breeding programs. For these purpose, a field experiment was carried out using randomized complete block design with four replications in 2016 and 2017 at Hashem-Abad ...
متن کاملRegistration of Four Exotic Germplasm Lines Derived from an Introgressed Population of Cotton
240 Journal of Plant Registrations, Vol. 4, No. 3, September 2010 Pressure from the global textile market has dramatically increased spinning speed in the modern U.S. textile industry. Acceleration of spinning speeds toward 400 m min−1 requires high fi ber quality to reduce the cost to industry (Foulk et al., 2009). Broadening the genetic base in Upland cotton is essential for improvement of fi...

Gutierrez et al., 2002; Lu and Myers, 2002). Genetic distances could be as low as 1 to 3%. Research in AustraGenetic diversity in modern upland cotton cultivars (Gossypium lia, China, and Pakistan obtained similar results (Multani hirsutum L.) is thought to be narrow, thus limiting genetic advance. Robust information on the genetic relatedness among currently grown and Lyon, 1995; Zuo et al., 2...
متن کاملInheritance and variation of lint yield and fiber traits in a partially introgressed (Gossypiumbarbadense L. × G. hirsutum L.) population of cotton
The objective of this study was to evaluate a partially introgressed (Gossypiumbarbadense L. × G. hirsutum L.) population of cotton for two years. The traits that studied were lint yield per plant, lint %, fiber length, fiber strength and micronaire. A total of 31 cytogenetically stable lines (2n=4x=52) were produced from a cross between a G. barbadense line, Carnak and a G. hirsutumline, 4S,...
