“…However, some data suggest that fiber strength may not always segregate in a quantitative manner, especially in the inheritance analysis of some introgression lines. Richmond (1951) indicated that recovery of high strength segregated from a small backcross population during introgression of strength from the triple hybrid Gossypium thurberi × Gossypium arboreum × G. hirsutum as evidence for only a few major genes controlling strength. Meredith (1977Meredith ( , 1992 came to a similar conclusion.…”

Molecular tagging of a major QTL for fiber strength in Upland cotton and its marker-assisted selection

Fiber is a basic raw material in the textile industry. The changes in spinning technology have in common the requirement of unique and often greater cotton fiber quality, especially strength, for processing. We used a Gossypium anomalum introgression line, 7235, characterized by good fiber quality properties, to identify molecular markers linked to fiber-strength QTLs. By the use of F(2) and F(3) populations derived from a cross between 7235 and TM-1, a genetic standard of Upland cotton, nine molecular markers, three SSRs and six RAPDs, were identified to be linked to two QTLs for fiber strength. One was a major QTL, QTL(FS1), detected both in Nanjing and Hainan, China, and the Texas College Station, USA. It was found to be associated with eight markers and explained more than 30% of the phenotypic variation. QTL(FS1) was mapped to chromosome 10. The major QTL in 7235 was identified to be transferred from an Acala 3080 cotton. The marker-assisted selection revealed that DNA markers linked to this QTL could be used in increasing the fiber strength of commercial cultivars.

However, since intra-varietal Systematic cotton breeding is considered to have selection offers a rapid means of improvement, commenced in the early twentieth century (Har-particularly at the start of a crop improvement land, 1949; Richmond, 1951;Brown & Ware, programme, the amount of genetic variability in 1958, p. 51). It has evolved through a number of modern cotton varieties is important.…”

“…In contrast, American varieties of Gossypium hirsutum are considered to have evolved from a rather restricted genetic base (Richmond, 1951;Ramey, 1966), and are being bred under high yield conditions in which outcrossing is slight because of frequent applications of insecticides (Meyer, 1969). These highly developed American varieties have been subjected during the last six decades to stringent selection for 'purity' and phenotypic uniformity, and a number of workers have considered that their variability would be small and unimportant (e.g.…”

However, Justus (1960) found significant genetic variability in the U.S.A. variety Stoneville 62 (maintained under open pollinated conditions) in each of the traits fibre fineness, lint percentage, percentage first harvest (first harvest expressed as a percentage of total harvest) and lint yield.…”

Populations of spaced plants of each of the four American upland cotton varieties Deltapine Smooth Leaf, Rex Smooth Leaf, Pope, and Rex and one African upland variety, Bar 7/8, were grown in the 1965-6 wet season at Kimberley Research Station, in the Ord River valley, Western Australia. The number of bolls, boll weight, lint percentage, seed cotton yield, lint yield, micronaire value, mature height, and morphological type were recorded for each plant.For all varieties the range of each attribute was wide; for example, for a typical variety, boll weight ranged from 3-0 to 7-8 g, lint percentage from 30-5 to 43-5%, micronaire value from 3-3 to 5-9 units, and mature height from 78 to 195 cm.The most variable varieties judged on coefficients of variation were those maintained at the station for the longest period without selection while the most recent accession was the least variable.Frequency distributions for all attributes in each population departed significantly from normality: the majority showed both significant skewness and kurtosis. Positive skewness shown for the yield parameters seed-cotton yield, lint yield, boll number and boll weight in all varieties suggested there was scope for improvement by selection. Negative skewness for lint percentage was found in three varieties, suggesting previous intense selection for this trait. The coefficient of variation of lint percentage with one variety (Deltapine Smooth Leaf) was considerably less than that recorded 30 years earlier for its predecessor D x PL 11 A.Covariance adjustments to seed cotton yield of individual plants, based on various hypotheses of the relationship between a plant's yield and that of its neighbours failed to give reductions of consequence in the variability of yield. It was concluded that inter-plant influences were far more complex than the models assumed.

34.3, and 22.2%, respectively of the total variance components as indicated in the analysis of 36 yr of high Textile mills in the USA require strong cotton fiber (Gossypium quality cultivar testing (Meredith, 2003). The lack of hirsutum L.) for modern high-speed textile operations. The primary breeding progress for fiber quality has led some (Felker, objective of this study was to determine the inheritance of strength descending from FTA 263-20 (FTA). FTA was developed by introgres-2001) to question if modern U.S. cotton breeders were sion into G. hirsutum from G. arboreum L., G. thurberii Todaro, and mindful of their best customers' fiber needs. G. barbadense L. Five backcrosses (BCs) into 'Deltapine 16' (DP 16) Fiber bundle strength (T 1 ) has long been recognized followed by six BCs into DP 90ne were made. In 2001, three sets as being inherited as a quantitative trait (Richmond, of 64 BC 6 F 2 :F 3 progenies were evaluated for strength. Significant 1951). It is generally assumed that high fiber strength variability for F 2 :F 3 strength (F ϭ 2.79), yield, three yield components, is caused by many genes. Self and Henderson (1954) in and four other fiber traits were detected. From a three replication populations involving high strength AHA 50 and 'Half test, strength gene number(s) estimates ranged from 1.10 to 1.29 and and Half' reported Pressley strength was determined by combined over sets was 1.23 genes.
