Stability Analysis of Upland Cotton in Texas
Crop Science, 2013ABSTRACTCotton (Gossypium hirsutum L.) is a high value cash crop for the southern United States with an annual production of over 3.2 million t. For breeders to fully maximize yield potential and to improve fiber properties of new cotton cultivars, it is important to use representative test locations to evaluate genotype × environment (G×E) effects and

Immature Fiber Mutant of Upland Cotton
Crop Science, 1990The inheritance of a mutant character of Upland cotton, Gossypium hirsutum L., that results in abnormal fiber development is described, and the mutant is compared to environmentally induced immature fiber. The phenotype and fiber properties of the mutant resemble those found in bolls that have experienced arrested development due to environmental ...

Early Generation Testing in Upland Cotton
Crop Science, 2006Early generation testing (EGT) is often used to identify segregating populations that are expected to contain the greatest frequency of favorable genotypes and to eliminate inferior populations with limited promise. The goal of this study was to determine if EGT methods utilized in cotton (Gossypium hirsutum L.) at College Station (CS) and Weslaco (WS),

Seedling Drought Tolerance in Upland Cotton
Crop Science, 2005Combining root morphological and plant physiological traits associated with drought tolerance should result in improved drought resistance in cotton (Gossypium hirsutum L.). This study was designed to evaluate the response of root growth of selected Converted Race Stocks (CRS), TAM94L‐25, and ‘Lankart 142’ (LK 142) under water stress and nonstressed ...

Cotyledons in Upland Cotton: How Important Are They?
Crop Science, 2008Seedlings of upland cotton (Gossypium hirsutum L.) are vulnerable to the partial or complete loss of their cotyledons due to an array of biotic and abiotic causes. These experiments were conducted in the field over a 4‐yr period to determine the effects of such losses in the early vegetative cotyledon growth stage on lint yield, selected lint yield ...

Frequency and Diversity of Fungi Colonizing Tissues of Upland Cotton
Mycopathologia, 2004A study of the mycoflora of upland cotton in Alabama was conducted throughout the 2000 and 2001 growing seasons. Plants were sampled at seedling, first bloom, full bloom, and maturity stages of development. Thirty-seven genera representing 58 species of fungi were isolated, including 9 species of Fusarium. Fusarium oxysporum, F. solani, and F. equiseti

Dynamic infection of Verticillium dahliae in upland cotton
Plant Biology, 2019Abstract Verticillium wilt, an infection caused by the soilborne fungus Verticillium dahliae, is one of the most serious diseases in cotton. No effective control method against V. dahliae has been established, and the infection mechanism of V. dahliae in upland cotton remains unknown. GFP‐tagged V.

A study of heterosis in upland cotton (Gossypium hirsutum L.)
Theoretical and Applied Genetics, 1976Heterosis (over mid parent) and "useful" heterosis (over commercial variety H14) estimates were obtained from a line x tester analysis of crosses involving thirteen diverse female parents with two locally adapted varieties H14 (local standard) and J34. Marked heterosis was observed for seed cotton yield, boll number and halo length.

A-genome cotton as a source of genetic variability for Upland cotton (Gossypium hirsutum)
Genetic Resources and Crop Evolution, 2006Since Upland cotton (Gossypium hirsutum) is known to have relatively low levels of genetic diversity, a better understanding of variation and relationships among possible sources of novel genes would be valuable. Therefore, analysis of genetic variation of the genus Gossypium, especially the diploids, which are the putative donors of the A and D ...

Upland and Pima Cotton as Pollen Donors for Male‐Sterile Upland Seed Parents
Crop Science, 1991The development of an interspecific hybrid cotton has been hampered by a serious problem with pollination. A field study was conducted to compare Pima cotton (Gossypium barbadense L.) with upland cotton (G. hirsutum L.) as a pollen source for hybrid seed production using male‐sterile upland seed parents. Male‐sterile cotton flowers were hand pollinated
