Abstract:
... In recent years, reniform nematodes have become a serious pest to U.S. cotton production. The USDA-ARS at Weslaco, TX has maintained a nursery for evaluating cotton cultivar response to reniform nematodes. Thirty-six entries from private and public breeding programs were evaluated in 2002. Average yield reduction between the fumigated and reniform nematode infested plots was 22.5%. Fourteen entrie ...

Abstract:
... Amplified fragment length polymorphism (AFLP) marker system has had broad applications in biology. However, the anonymous AFLP markers are mainly amplified from non-coding regions, limiting their usefulness as a functional marker system. To take advantages of the traditional AFLP techniques, we propose substitution of a restriction enzyme that recognizes a restriction site containing ATG, called A ...

Abstract:
... Varying fiber length distributions of cotton, Gossypium hirsutum L., impacts its spinning performance. Advanced Fiber Information System (AFIS) facilitates the analysis of the length distribution of individual fibers in cotton. Quantile regression is a variant of standard regression with which conditional quantile values can be calculated by minimizing weighted sums of absolute deviations across t ...
