Quality traits in cotton
-
Gossypium barbadense (Sea Island, Egyptian or Pima cotton) cotton has high fiber quality, however, few studies have investigated the genetic basis of its traits using molecular markers. Genome complexity reduction approaches such as genotyping-by-sequencing have been utilized to develop abundant markers for the construction of high-density genetic maps to locate quantitative trait loci (QTLs).

Heterosis, a multigenic complex trait extrapolated as sum total of many phenotypic features, is widely utilized phenomenon in agricultural crops for about a century. It is mainly focused on establishing vigorous cultivars with the fact that its deployment in crops necessitates the perspective of genomic impressions on prior selection for metric traits. In spite of extensive investigations, the actual mysterious genetic basis of heterosis is yet to unravel. Contemporary crop breeding is aimed at enhanced crop production overcoming former achievements.

A high density SLAF-SNP genetic map and QTL detection for fibre quality traits in Gossypium hirsutum
Upland Cotton (Gossypium hirsutum) is a very important cash crop known for its high quality natural fiber. Recent advances in sequencing technologies provide powerful tools with which to explore the cotton genome for single nucleotide polymorphism marker identification and high density genetic map construction toward more reliable quantitative trait locus mapping.

Improving fiber quality and yield are the primary research objectives in cotton breeding for enhancing the economic viability and sustainability of Upland cotton production. Identifying the quantitative trait loci (QTL) for fiber quality and yield traits using the high-density SNP-based genetic maps allows for bridging genomics with cotton breeding through marker assisted and genomic selection.

Fiber quality is an important economic trait of cotton, and its improvement is a major goal of cotton breeding. To better understand the genetic mechanisms responsible for fiber quality traits, we conducted a genome-wide association study to identify and mine fiber-quality-related quantitative trait loci (QTLs) and genes.

Seed cotton yield and fibre quality traits are governed by polygenes and these traits are highly influenced by the environment. Hence, selection merely based on yield is not effective. In order to enhance the yield potential of the cotton varieties, knowledge on the direct contribution of different characters to yield would be highly important for formulating a selection programme.

The study was carried out at cotton research area, CCS Haryana Agricultural University, Hisar (India) during 2014 and 2015 kharif season. Fifteen cotton lines (which have maximum diversity) and four testers (which are known as well adapted and high yielding) were crossed in a line x tester mating design in 2014.

The upland cotton (Gossypium hirsutum L.) accounts for about 95% of world cotton production. Improving upland cotton cultivars has been the focus of worldwide cotton breeding programs. In cotton, seed cotton yield, yield contributing and fibre quality traits are under the control of polygenes or quantitative trait locus (QTL), for these traits QTL analysis holds a great promises these are the genomic regions that links the information between phenotypic (trait measurement) and genetic data (molecular markers) and explain the genetic basis of variation in complex traits.

Cotton is the very important commercial and cash crop, it is a very much necessary to improve the Superior agronomic traits to withstand against biotic and abiotic stress in the field and fiber qualities to meet requirement of advance spinning technology. Cotton improvement through conventional breeding is time consuming, in this context molecular markers found that efficient tool to accelerate the plant breeding program in cotton improvement. At present variety of molecular markers are available, choice of molecular marker depends on the user.

To investigate the water-deficit tolerance, 3 cotton genotypes (Bunny Bt, Pratima and Anjali.) were grown under normal irrigation and water-deficit conditions. Moisture is a key factor affecting growth and yield of Cotton in which stress is the most important factor limiting crop productivity due to adverse effect on fruit production, square/boll shedding and lint yield as well as fiber quality properties of Cotton. If water supply is limited during boll development it could result in significantly lower yields. In this study stress imposed with four watering treatments viz.

The present investigation was carried out during 2012-13 at ARS, Siruguppa with an objective of determine the extent of commercial Heterosis for fiber quality traits in F1 hybrids obtained by crossing 10 parents in half dialle fashion. Several hybrid combinations showed very good per se performance for all the traits under study and commercial Heterosis for 2.5% span length. These lines can sever as a potential donor for genetic improvement of cotton after further evaluation, fixation and selection.
