1. Quantitative trait loci controlling plant architectural traits in cotton

Author:
Song, Xianliang; Zhang, Tianzhen
Source:
Plant science 2009 v.177 no.4 pp. 317-323
ISSN:

Subject:
height; crop yield; genetic markers; quantitative trait loci; backcrossing; hybrids; Gossypium hirsutum; genotype; phenotypic variation; fiber quality; cultivars; epistasis; genotype-environment interaction; branches; bolls; cotton; plant architecture; internodes; Gossypium barbadense; environmental factors; agronomic traits; linkage (genetics)
Abstract:
... Cotton plant architecture is an important characteristic influencing the suitability of specific cotton varieties in cultivation, fiber yield and quality. However, complex multigenic relationships and substantial genotype-environment interaction underlie plant architecture, and will hinder the efficient improvement of these traits in conventional cotton breeding programs. An enhanced understanding ...

2. Genetic association of lint yield with its components in cotton chromosome substitution lines

Subject:
Gossypium hirsutum; cotton; crop yield; lint cotton; yield components; bolls; substitution lines; Gossypium barbadense; chromosomes; interspecific hybridization; hybrids
Abstract:
... Dissection of the genetic relationship between lint yield and its yield components at the chromosome level may provide an additional avenue for yield enhancement in cotton (Gossypium hirsutum L.). Based on the conditional additive-dominance (AD) genetic model, we investigated the genetic structures of lint yield with its three component traits, lint percentage, boll weight, and boll number, using ...

3. Effects of Chromosome-Specific Introgression in Upland Cotton on Fiber and Agronomic Traits

Author:

Gossypium hirsutum; Gossypium barbadense; interspecific hybridization; cotton; introgression; chromosome substitution; substitution lines; chromosomes; fiber quality; agronomic traits; yield components; crop yield; additive gene effects; plant breeding; lines; genotype-environment interaction; hybrids; quantitative genetics
Abstract:
... Interspecific chromosome substitution is among the most powerful means of introgression and steps toward quantitative trait locus (QTL) identification. By reducing the genetic "noise" from other chromosomes, it greatly empowers the detection of genetic effects by specific chromosomes on quantitative traits. Here, we report on such results for 14 cotton lines (CS-B) with specific chromosomes or chr ...

4. Comparison of bulk F2 performance testing and pedigree selection in thirty pima cotton populations

Author:
Percy, R.G.
Source:
Journal of cotton science 2003 v.7 no.4 pp. 123
ISSN:
1524-3303
Subject:
Gossypium barbadense; lint cotton; plant breeding; artificial selection; selection methods; crossing; progeny testing; early selection; hybrids; pedigree; lines; agronomic traits; fiber quality; crop yield; correlation; Arizona
Abstract:
... The objective of early generation testing is to increase breeding efficiency through early identification of superior heterogeneous populations. Bulk F2 testing has gained adherents among the cotton breeding community with little data to support its efficacy. The goal of this study was to compare bulk F2 performance with historical pedigree selection records to determine the degree of corresponden ...

5. Variation in Water-Use Efficiency and Its Relation to Carbon Isotope Ratio in Cotton

Author:
Saranga, Yehoshua; Flash, Igal; Yakir, Dan

Crop science 1998 v.38 no.3 pp. 782-787

Subject:
cultivars; crop quality; hybrids; irrigation; Gossypium hirsutum; water use efficiency; interspecific hybridization; Gossypium barbadense; drought; selection criteria; carbon; crop yield; genetic variation; photosynthesis; stable isotopes; Israel
Abstract:
... Cotton (Gossypium spp.) is often exposed to drought, which adversely affects both yield and quality. Improved water-use efficiency (WUE = total dry matter produced or yield harvested / water used) is expected to reduce these adverse effects. Genetic variability in WUE and its association with photosynthetic rate and carbon isotope ratio (¹³C/¹²C) in cotton are reported in this paper. WUE of six co ...

6. Early-Maturing, Short-Statured American Pima Cotton Parents Improve Agronomic Traits of Interspecific Hybrids

Author:
Percy, Richard G.; Turcotte, E. L.

Abstract:
... The commercial potential of interspecific cotton hybrids (Gossypium hirsutum L. ✕ G. barbadense L.) remains unrealized due to several fiber-quality deficiencies and the agronomic traits excessive vegetative vigor and generally slow maturation rates. This study examined whether four G. barbadense strains, bred for short stature and early maturity, favorably affect hybrid plant height, earliness, an ...
