Genetic analysis of Upland cotton dynamic heterosis for boll number per plant at multiple developmental stages

Yield is an important breeding target. As important yield components, boll number per plant (BNP) shows dynamic character and strong heterosis in Upland cotton. However, the genetic basis underlying the dynamic heterosis is poorly understood. In this study, we conducted dynamic quantitative trait loci (QTL) analysis for BNP and heterosis at multiple developmental stages and environments using t...

1928 Boll development and seed rot

Boll rot is a common term used to describe a variety of diseases that influence the appearance of the mature cotton boll, even though the causal agents may differ substantially from each other. Approximately 170 organisms are described as causing “boll rot” (Anonymous, 2001). Generally, the boll will not mature completely, or if it matures under an area of high humidity, fungal organisms may at...

Nitrogen (N) Application Gradually Enhances Boll Development and Decreases Boll Shell Insecticidal Protein Content in N-Deficient Cotton

Expression of insecticidal protein in transgenic Bacillus thuringiensis (Bt) is lower in cotton reproduction organs, especially during boll development period. The current study investigated the effects of nitrogen fertilization under nitrogen deficit on boll development and Bt toxin content in boll shell, which is the first target of boll worm harm. The protein synthesis and degradation in thi...

This shortcoming may be addressed The purpose of this study was to determine the by directly estimating Mississippi Delta producers' economic risk efficiency of implementing a boll benefits and costs of a BWE program. However, weevil (Anthonomus grandis [Boheman]) eradicaonly pest control costs prior to BWE program adoption (BWE) program in cotton (Gossypium hirsutum tion are av...
