Yield remains the ultimate measure of the crop, although the ever-increasing demand for higher fiber quality makes this factor a close second in priority. With morethan 70% of the U.S.

crop exported, fiber quality will become the single most important factor for U.S. cotton in the foreseeable future. management. Primitive race stocks of cotton have been identified as an important source of resistance to a wide range of insect pests, but they have not been evaluated for resistance to cotton fleahopper.

The objective of this study was to evaluate selected groups of primitive race stocks of Gossypium hirsutum L. for resistance to cotton. Bayer Cotton Seed International, Leland, MSUSA Euphytica () – DOI /s AFLP marker associations with agronomic and fiber traits in cotton Jixiang Wu Æ Johnie N.

40% of the variability for yield between hybrids could be accounted for by four traits. This. The cotton seeds were extracted using a cotton gin machine.

Two sets of traits were established, the group I formed by the agronomic traits, i.e., fiber yield (Fiberyield), boll mean weight (Wmeanboll), percentage of fiber (Percfiber) and weight of seeds (Wseeds), the group II was formed by the technological traits of the fiber, i.e., length.

unique and often greater cotton fiber quality, especially fiber strength for processing (Deussen, ). Many cotton research programs require measure-ments of agronomic and fiber quality traits such as lint percentage, boll weight, and 50% fiber span length, fiber bundle strength, and fineness (micronaire reading,Cited by: In this chapter, the focus will be on the tensile behavior of cotton fibers through discussions of six key subjects.

The first subject deals with the structural features of cotton fiber, particularly those that are directly related to the tensile behavior of cotton fiber including the degree of crystallinity, the degree of orientation, the convolution effect, and the tapering effect of the by: 3.

Breeding cultivars and germplasms of cotton with higher yield and better resistance to pests is an environmentally friendly way of improving production with little cost to the producer. We propose to use standard breeding protocols to improve yield, fiber quality, and pest resistance in upland cotton.

Crosses will be made among adapted parents and resistance. COTTON HYBRIDS In India, hybrid cotton era started since with the release of world’s first cotton hybrid “H 4” from Cotton Research Station Surat of Gujarat Agricultural University. This hybrid was developed by Late who is rightly called as father of hybrid cotton.

This hybrid, by virtue of its high yield potentialFile Size: KB. Soil pH, soil P, and soil organic matter were correlated with fiber yield and a number of fiber properties, including micronAFIS, immature fiber fraction, fine fiber fraction, cross-sectional area, and micronaire.

Genetic diversity in some cotton germplasm populations developed by public breeding programs in U.S.

The two-volume Handbook of natural fibres is an indispensible tool in understanding the diverse properties and applications of these important materials. Volume 1: Types, properties and factors affecting breeding and cultivation is an essential guide to a wide range of natural fibres, and highlights key techniques for their improvement.

Abstract. Normal- and late-planted cotton (Gossypium hirsutum L.) often differ in fiber properties, especially those properties related to fiber secondary wall field study was conducted to (i) determine the effect of planting date on fiber properties of bolls at two flowering times, and (ii) determine the relationship between fiber properties and canopy photosynthesis.
