“…The highest total free amino acid (44.00 mg g -1 ) was estimated from the seeds of the genotype BC-0125 and the lowest (27.10mg g -1 ) was obtained from the seeds of BC-0252 genotype. Such differences between the genotypes in free amino acid composition also reported by Khattab et al 38 in some cotton seeds species. Total free amino acid in stored cotton seed increased progressively over the storage and it was higher in seeds of cloth bag as compared to polythene bag under ambient condition (Figure 3).…”

Variation in the biochemical attributes of the seeds from five genotypes (CB-8, SR-08, BC-0125, BC-0236 and BC-0252) of cotton (Gossypium hirsutum L.) was appraised. Seeds were packed in polythene and cloth bag and stored over 14 months to determine the changes in biochemical composition under ambient condition. Results revealed that total soluble sugar, total soluble protein and oil content of cotton seeds decreased and total free amino acid increased with the increase of storage period. However, decreasing rate of total soluble sugar, total soluble protein and oil content and increasing rate of total free amino acid was slower in polythene bag and faster in cloth bag throughout the storing period. Among the genotypes, BC-0252 showed slower degradation of biochemical composition of stored seeds than that of seeds of other genotypes.

QTL Mapping Based on Different Genetic Systems for Essential Amino Acid Contents in Cottonseeds in Different Environments

et al. 2013

Cottonseeds are rich in various essential amino acids. However, the inheritance of them at molecular level are still not defined across various genetic systems. In the present study, using a newly developed mapping model that can analyze the embryo and maternal main effects as well as QTL × environment interaction effects on quantitative quality trait loci (QTLs) in cottonseeds, a study on QTL located in the tetraploid embryo and tetraploid maternal plant genomes for essential amino acid contents in cottonseeds under different environments was carried out, using the immortal F2 (IF2) populations from a set of 188 recombinant inbred lines derived from an intraspecific hybrid cross of two upland cotton germplasms HS46 and MARKCBUCAG8US-1-88 as experimental materials. The results showed a total of 35 QTLs associated with these quality traits in cottonseeds. Nineteen QTLs were subsequently mapped on chromosome 5, 6 and 8 in sub-A genome and chromosome 15, 18, 22 and 23 in sub-D genome. Eighteen QTLs were also found having QTL × environment (QE) interaction effects. The genetic main effects from QTLs located on chromosomes in the embryo and maternal plant genomes and their QE effects in different environments were all important for these essential amino acids in cottonseeds. The results suggested that the influence of environmental factors on the expression of some QTLs located in different genetic systems should be considered when improving for these amino acids. This study can serve as the foundation for the improvement of these essential amino acids in cottonseeds.

The component triacylglycerols of six seed oils of the Malvaceae family—Gossypium barbadense (Egyptian cotton),Hibiscus cannabinus (kenaf),Hibiscus sabdarifa (roselle), two varieties ofHibiscus esculentas (okra) andAlthea rosea (ketmia, hollyhock or Egyptian hemp)—have been determined by using the lipase hydrolysis technique. The oils were found to contain triacylglycerols belonging to trisaturated (1.0–2.1), disaturated‐monounsaturated (12.3–20.9), monosaturated‐diunsaturated (42.3–46.6) and triunsaturated (30.1–44.2) types of triacylglycerols.
