introduction reduced availability of water resources in many arid countries including iran, particularly in response to the indiscriminate harvesting of water reservoirs and climate change, has created concerns. therefore, the sustainable use of water resources especially in agriculture is a necessity for these countries. strategies such as deficit irrigation and superabsorbent application are ...

Historically, reselection, pedigree, and massselection breeding methods have been used to develop open-pollinated cultivars of upland cotton (Gossypium hirsutum L.). As a result, modern cotton cultivars should have accumulated additive genetic effects with time, while also possessing fewer nonadditive gene effects than obsolete cultivars. A topcross test was conducted to compare the heterotic e...

cotton are an important source of useful genetic variability (Percival, 1987; Meredith, 1991; McCarty and JenPrimitive accessions of cotton, Gossypium hirsutum L., may prokins, 1992; McCarty et al., 1995). Percival and Kohel vide useful traits for cultivar development. Genetic effects for yield, yield components, and fiber traits were analyzed for five generations (1990) reviewed the collection...

‘‘The Cotton Diversity Database’’ (http://cotton.agtec.uga.edu) is a Web resource for cotton (Gossypium spp.) phenotypic and genomic data. A primary goal for this resource is to provide both a useful management tool for breeders and other applied scientists and a research tool for genetic and genomic scientists. The resource contains four interface suites that include displays for each of the a...
