Background: Cotton with coevolving pests has been grown in India more than 5000 years. Hybrid cotton was introduced in the 1970s with increases in fertilizer and in insecticide use against pink bollworm that caused outbreaks of bollworm. Hybrid Bt cotton, introduced in 2002 to control bollworm and other lepidopteran pests, is grown on more than 90 % of the cotton area. Despite initial declines,...
ABSTRACT Good quality seeds of cotton cultivars often escaped pre-emergence damping-off incited by Pythium spp. and Rhizopus oryzae, and they were resistant to postemergence damping-off incited by Rhizoctonia solani. Poor quality seeds, however, were highly susceptible to both phases of seedling disease and required seed treatment in order to survive. Pre-emergence damping-off incited by Pythiu...
The conducted study, with focus on the earliness and opening rate of bolls, other economic traits introgressive cotton lines, was carried out from 2017 to 2019 at Institute Genetics Plant Experimental Biology, Evolution Biology Department, in Chirchik State Pedagogical Institute, Tashkent, Uzbekistan. Overall, lines were found ripen two 13 days earlier than a standard cultivar C-6524. Particula...
RNA interference (RNAi), is a powerful new technology in the discovery of genetic sequence functions, and has become a valuable tool for functional genomics of cotton (Gossypium sp.). The rapid adoption of RNAi has replaced previous antisense technology. RNAi has aided in the discovery of function and biological roles of many key cotton genes involved in fiber development, fertility and somatic...
The high demand for cotton production worldwide has presented a need for its standardized classification. There currently exists trained classers and instrumentation to distinguish key cotton quality parameters, such as some trash types and content. However, it is of interest to develop a universal instrumental method with higher trash identification specificity. A program was implemented to de...
The saw gin, the primary technical device used in cotton ginning process, is responsible for separating fiber from seed. After being cleansed of khaschops and dried to desired humidity drying, cleaning, cleaning shops, seeded transferred main building business (separation fiber). Up now, 4DP-130, 5DP-130, DPZ gins have been employed operations spin medium cotton. machine's operation, which sepa...
BACKGROUND Characterizing the spatial patterns of gene flow from transgenic crops is challenging, making it difficult to design containment strategies for markets that regulate the adventitious presence of transgenes. Insecticidal Bacillus thuringiensis (Bt) cotton is planted on millions of hectares annually and is a potential source of transgene flow. METHODOLOGY/PRINCIPAL FINDINGS Here we m...
Poor air quality in some areas of the US has caused regulators to increase regulatory pressure on sources of air pollution. Historically, cotton producers have not been targeted by regulators to reduce emissions through mandatory implementation of particulate matter (PM) control strategies. However, the use of inaccurate PM emission factors for field operations (including cotton harvesting) has...
Cotton is considered as the foremost commercially important fiber crop and is deemed as the backbone of the textile industry. The productivity of cotton crop, worldwide, is severely hampered by the occurrence of pests, weeds, pathogens apart from various environmental factors. Several beneficial agronomic traits, viz., early maturity, improved fiber quality, heat tolerance, etc. have been succe...
