“…The oil content in parents ranged from 17.7 (%) to 22.1 in F 1861 Pandey (1977) reported that the variability for oil content in improved strains of G. hirsutum ranged from 14.5 to 22.0% with mean of 19.2% (Table 5). The earlier workers, Dani (1989), Dani (1991), Gotmare et al (2004), Khan et al, (2007a) and Sharma et al, (2009) similar findings, and supported our results. Hassan et al (2005) studies exhibited the performance of Egyptian cotton cultivars for cottonseed oil percentage and found significant mean differences.…”

An investigation was carried out to assess the expression of per se performance and heterotic effect for seed oil, seed protein besides various yield attributing characters studied from 28 hybrids involving four adapted varieties as lines and the seven testers in line x tester analysis. A wide range of variability was observed for seed oil content in the parents and their 28 hybrids. The seed oil content in parents ranged from 17.0 to 22.1%, and hybrids varied from 17.7 to 22.9%.The hybrid, MCU 12 x SOCC 11 exhibited significant positive heterotic effect and per se performance for boll weight. The hybrid MCU 5 x SOCC 17 had high per se performance and positive significant heterotic effect for seed protein with seed cotton yield. Two hybrids showed high heterotic effect and per se performance for seed protein content. The hybrid MCU 12 x SOCC 17 exhibited higher per se performance and heterotic effect for seed cotton yield along with seed oil content and MCU 5 x SOCC 17 recorded more seed protein combined with seed cotton yield. Four hybrids revealed greater per se performance and positive heterosis for seed oil content. Of these, Surabhi x TCH 1646 exhibiting highest per se performance, heterotic effect was found to be best for directional selection.

Genetic analysis and QTL mapping of oil content and seed index using two recombinant inbred lines and two backcross populations in Upland cotton

et al. 2016

Cottonseed is one of the main by-products of cotton. To explore the genetic composition of oil content (OC) and seed index (SI) is helpful for utilizing the cottonseed. Under multiple environmental conditions, the genetic structures of OC and SI were explored using two recombinant inbred lines (RILs) and corresponding backcross (BC) populations in Upland cotton. Twenty-four and 31 quantitative trait loci (QTLs) for OC and SI, respectively, were detected using composite interval mapping, in which 9 QTLs for OC and 18 QTLs controlling SI were simultaneously identified in more than two environments or two populations. Fortyseven and 37 QTLs with main effects (M-QTLs) for OC and SI and 114 and 74 QTLs involved in digenic interactions (E-QTLs), respectively, identified by inclusive composite interval mapping. On average, the EQTLs explained a larger portion of the phenotypic variation than the MQTLs did. It was concluded that additive effects of single-locus and epistasis derived from complementary loci with few detectable single-locus effects played an important role in oil content and seed index in Upland cotton.

“…Differentiation between the hair types has been maximised to produce the white lint in elite cultivars. Cottonseed oil accumulates in the cytoplasm of the seed embryo cells (Gotmare et al, 2004); it is not associated with the gossypol glands. Descriptions of the seed are provided by Hopper and McDaniel (1999) and Ritchie et al (2007), and an overview of advances in knowledge of the development of seed and fibre is provided by Ruan (2005).…”
