Abstract:
... The rate of boll weevil, Anthonomus grandis Boheman, oviposition was tested on 252 cotton lines, Gossypium hirsutum L. and G. barbadense L., in a nonreplicated mass screening procedure. Boll weevil oviposition was reduced in 26 lines. Replicated tests were performed on six of these by using the A & M laboratory strain and a Mississippi field strain of weevils. The two strains ranked the six cotton ...

The objective of this investigation was to test a resistance gene analog (RGA) anchored marker system, called amplified fragment length polymorphism (AFLP)-RGA in cotton (spp.). The AFLP-RGA analysis us ...

Abstract:
... Lint of interspecific hybrids (ISHs) of cotton (Gossypium hirsutum L. × G. barbadense L.) tends to contain a high proportion of impurities which reduce the quality of yarn and fabric. Much of these impurities are related to the presence of motes (aborted ovules or seeds) the seed cotton produced by these hybrids. This study was aimed at determining the effect of motes of various sizes and fiber ph ...

Abstract:
... Most modern cultivars of extra-long-stapled cotton (Gossypium barbadense L.) display glabrous stems and variable densities of pubescence on leaves. These cottons produce long, strong, and fine fibers. The Tanguis cultivars, and the American Pima Stock, E-2, produce coarse, although lengthy and strong, fibers. Because Tanguis and E-2 have dense tomentum on leaves and stems, there arose the question ...
