High density 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).

Quantitative trait loci (QTL) mapping provides a powerful tool to unravel the genetic bases of cotton yield and its components, as well as their heterosis. In the present study, the genetic basis underlying inbreeding depression and heterosis for yield and yield components of upland cotton was investigated in recombinant inbred line (RIL), immortalized F2 (IF2), and two backcross (BCF1) populations based on a high-density SNP linkage map across four environments.

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.

Cotton is a leading natural fiber crop. Beyond its fiber, cottonseed is a valuable source of plant protein and oil. Due to the much higher value of cotton fiber, there is less consideration of cottonseed quality despite its potential value.

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.

A field experiment was conducted at Anbil Dharmalingam Agricultural College and Research Institute, Tiruchirapalli during winter season of 2019 to study the effect of subsurface drip irrigation- fertigation regimes on stalk yield, seed cotton yield and economics of high density cotton cultivation in sodic soil. The experiment was laid out in factorial randomized block design with three replications.

A field experiment was conducted to evaluate optimum plant density and suitable G. hirsutum cotton genotype for high density planting system under rainfed condition. Plant growth parameters, seed cotton yield and economics of cotton genotypes under various high planting densities were studied during kharif, 2013-14 to 2015-16 on medium soil. Increase in plant density has reduced monopodial branches plant-1 whereas, number of bolls plant were increased with increase in density.

The field study consisted of eight treatments, in which drip fertigation was given in T1 to T3 with 75%, 100% and 125%of recommended dose (RDF, 80:40:40 kg NPK/ ha) as straight fertilizers N and K (urea and MOP) and SSP was applied as basal dose. In T4 to T6 fertigation provided with 75%, 100% and 125% RDF of water soluble fertilizer (19:19:19). Drip irrigation with 100% RDF (all as soil application) was given in T7 and T8 with drip irrigation and STCR based fertilizer application.

High density planting system have the potential for increased yields in high yielding, high input production systems. To attain higher yields in high density planting system in cotton relative to conventional spaced cotton must depend on increased biomass production or partitioning to boll.

A field experiment was conducted during Kharif season of 2014-15 to evaluate the Effect of High Density Planting System (HDPS) and Genotypes on growth parameters and Yield contributing traits in upland cotton at Cotton Research Unit, Dr. P.D.K.V., Akola. The experiment was laid out in FRBD design consisting of four factors of plant densities viz., 45 x 10, 60 x10, 75 x 10 and 60 x 15 cm2 in main plots and three factors of cotton varieties i.e., AKH-081, NH-615 and Suraj in sub plots with replicated thrice.

A field experiment was conducted to study the mean incidence of major cotton insect pests during two consecutive seasons i.e. during kharif, 2010-11 and 2011-12 at CICR, Nagpur under high density planting system (HDPS) using different genotypes of G. hirsutum with different spacings. The main objectives of the work was to identify lines of G. hirsutum which have less infestation of major insect pests under HDPS system and to investigate whether the incidence is influenced by plant density.

Geographically and phenotypically diverse 860 G. hirsutum germplasm lines were evaluated under North Zone irrigated conditions of India during 2011-12 and 2012-13 for a different flower retention period, seed cotton yield and other desirable traits. The accessions initiate flowering at 60 days were having maturity period below 150 days, horizontal width less than 40 cm, hence showed suitability for high density cropping system (HDPS) for productivity enhancement. The accessions which flowers at 80 days are found to be semi spreading in nature.

Planting density is the most active factor and plays pivotal role in crop management practices. Hence plant density is the enduring topic for crop production improvement. The rational plant population is an important attribute to high yield of cotton, because it can provide a beneficial micro-environment within the canopy for plant growth and development as well as yield formation.
