Genome-wide association study (GWAS) has identified numerous significant loci for boll number (BN) and weight (BW), which play an essential role in cotton (Gossypium spp.) yield. The North Carolina design II (NC II) genetic mating population exhibits a greater of variations than other populations, may facilitate the identification additional genes.

The boll opening rate (BOR) is an early maturity trait that plays a crucial role in cotton production China, as BOR has significant effect on defoliant spraying and picking time of unginned cotton, ultimately determining yield fiber quality. Therefore, elucidating the genetic basis identifying stably associated loci, elite alleles, potential candidate genes can effectively accelerate molecular breeding process. In this study, we utilized mixed linear model (MLM) algorithm to perform genome-wide association study (GWAS) based 4,452,629 single-nucleotide polymorphisms (SNPs) obtained through whole-genome resequencing natural population 418 upland accessions phenotypic data acquired from five environments. A total 18 SNP loci were identified chromosome D11 are stable significantly with multiple Moreover, peak (23.703–23.826 Mb) was identified, GH-D11G2034 gene favorable allelic variation (GG) related found genomic region, increasing BOR. Evolutionary studies have shown may been subjected artificial selection throughout variety This provides valuable insights suggests its could be targets for improve cotton. However, further research needed validate function explore applications programs. Overall, contributes advancement improvement important implications sustainable development industry.

Abstract Background: Cotton is a significant crop for fiber production; however, seed shape-related traits have been less investigated in comparison to quality. Comprehending the genetic foundation of associated with shape crucial improving and quality cotton. Results: A total 238 cotton accessions were evaluated four different environments over period two years. Traits including thousand grain weight (TGW), aspect ratio (AR), length, width, diameter, roundness demonstrated high heritability variation, as indicated by phenotypic analysis. The association analysis involved 145 SSR markers identified 50 loci significantly six related shape. MON_DPL0504aa BNL2535ba influencing multiple traits, weight. Notably, such HAU2588a MUSS422aa had considerable influence on diameter roundness. represented an average variance between 3.92% length 16.54% (TGW). Conclusions: research finds key cotton, providing potential marker-assisted breeding. These findings establish framework breeding initiatives focused enhancing quality, hence advancing production.

Abstract Cotton fleahopper, Pseudatomoscelis seriatus Reuter (Hemiptera: Miridae), is an early season pest of upland cotton, Gossypium hirsutum L. Feeding damage from this causes square abscission. The response commercial cotton cultivars with varying maturity traits to fleahopper feeding was assessed. hypothesis that affects and late-maturing differently in delays yield. Field experiments natural artificial infestations were conducted Corpus Christi, TX. For the infestation experiment, 4 (DP 2020 B3XF, DP 2012 PHY 332 W3FE, 545 W3FE) assigned main plots, subplots either sprayed or not thiamethoxam insecticide control season. experiment used 2 B3XF as infested using single caging. In no-spray increased abscission, leading yield loss delayed boll maturity, especially classified late-maturing. Early maturing consistently showed faster opening regardless fleahopper. Artificial further confirmed reduced numbers, lower lint weights when are more resilient may be particularly useful areas high pressure, scheduling harvest desirable.
