2. Variability in staple length of some commercial varieties of cotton

Author:: Rea, H.E.

ISSN:: 0002-1962
Subject:: cotton; cultivars
Abstract:: ... The results of the data taken on the individual stalks within each of the 16 varieties grown in 1925 and 1926 justify the following conclusions: 1. A majority of the commonly grown commercial varieties of cotton, as judged by those involved in this study, possess a high degree of variability in staple length. These results emphasize the importance of giving more consideration and attention to unif ...

Abstract:: ... Frequency distributions presented for several characters in upland cotton approach a normal distribution and indicate considerable variation within the species. In the case of length, fineness, and strength the local varieties used as checks have become stabilized near the mean of the entire sample. Conscious selection for staple length has been practiced for many years, and apparently fineness ha ...

Pond sediment evidently contained microbial populations capable of decomposing the herbicide. Temperature was crucial in dicamba dissipation, especially in the presence of sediment. Influence of sediment on dissipation rate of dicamba was apparently augmented by light in s ...

Abstract:: ... The influence of five exotic cotton (Gossypium spp.) cytoplasms on yield, yield components, fiber properties, and insect populations was determined at Stoneville, Miss. The five cytoplasms were G. herbaceum L., G. arboreum L., G. anomalum Wawra ex Wawra & Peyr., G. barbadense L., and G. tomentosum Nutt. ex Seem. The five cytoplasms were combined by repeated backcrossing into the following upland c ...

Abstract:: ... The effect of early-season cotton, Gossypium hirsutum L., square loss and insect control (primarily thrips, Frankliniella occidentalis (Pergande)), on the ability of cotton plants to replace lost fruit as well as maintain lint quality was examined in several field trials of differing experimental design in Arizona during 1986-1987. All trials indicated some degree of compensation for damage to fru ...

Abstract:: ... The report describes in vitro plant regeneration from embryo axis explants of six cultivars of cotton. Induction of a maximum number of multiple shoots in all six cultivars could be achieved on Murashige and Skoog's (MS) salts and Gamborg's (B5) vitamins supplemented with 0.4 μM benzyladenine (BA) and 0.1 μM napthaleneacetic acid (NAA). Elongated shoots could be rooted on half strength medium supp ...

Abstract:: ... Information on soil-plant nutrient balance in India and elsewhere is scarce and mostly generalized. A review of earlier studies on nutrient balances was done to assess their relevance for researchers, policy makers, and farmers' understanding, to manage soil fertility for sustainable crop productivity. An on-farm nutrient balance study during 1995/1996 and 1996/1997 was designed to understand nutr ...

Abstract:: ... Nitrogen fertilization is a required production practice for cotton (Gossypium hirsutum L.) with risks arising from under- and over-fertilization. Tissue testing for diagnosing N deficiencies in crops can use leaf blades and the total N concentration, but this practice has not been rigorously examined in cotton. The primary objective of these experiments was to determine the leaf-N concentration o ...

The first is the Genes for Rent mechanism where a recipient country agrees with a GMO company to incorporate a GMO product (e.g., a Bt gene in cotton varieties) and pay a technology fee. The second is the Transgenic Breeding mechanism in which National Agricultural ...
