Inheritance, QTLs, and Candidate Genes of Lint Percentage in Upland Cotton

Abstract: Cotton (Gossypium spp.) is an important natural fiber plant. Lint percentage (LP) is one of the most important determinants of cotton yield and is a typical quantitative trait with high variation and heritability. Many cotton LP genetic linkages and association maps have been reported. This work summarizes the inheritance, quantitative trait loci (QTLs), and candidate genes of LP to facilitate LP genetic study and molecular breeding. More than 1439 QTLs controlling LP have been reported. Excluding replicate QT… Show more

“…The results from the aforementioned studies and the present study show that while yield improvement is an important goal of modern breeding efforts, it is a complicated trait that is heavily influenced by environment. Therefore, targeted selection using yield components with high heritability is a more widely utilized approach to improve the genetic yield potential of cotton than using yield alone as the selection criterion (Chapepa et al., 2022; Niu et al., 2022). However, in the current study, 4 out of 19 years (2009, 2011, 2014, 2020) were identified in which genotypic contributions to lint yield were greater than environmental contributions.…”

“…Given the importance of lint% in developing high-yielding elite commercial cotton varieties, numerous studies, including genetic mapping using segregating populations derived from biparental crosses and GWAS based on natural populations or germplasm collections, have identified hundreds of lint% QTLs ( Niu et al . 2022 ).…”

“…In every commercial cotton breeding program, lint output remains the top objective [39][40][41]. Lint percent, which is a component of lint output, was probably one of the first qualities to be chosen throughout the domestication process and in early breeding, and is still the most desired character [23,[42][43][44][45][46]. Environmental stability [47,48] and early maturity [49][50][51] are two more agronomic features that have risen in relevance [37].…”
