“…Jan et al (2017) reported that monopodia and seed cotton yield were significantly and positively correlated with each other. Phenotypic and genotypic association of number of monopodial branches and seed cotton yield reported by Ahuja et al (2016) and Alkuddsi et al (2013). However, the findings observed by the author in present research work are not in agreement to the results found by Killi (1995).…”

Background Gossypium arboreum is one of the cultivated diploids which has inherent resistance against insect pests and diseases, can withstand moisture stress, needs less nutrients and is suitable for erratic, less rainfall and marginal soils. Due to its smaller boll size and poor locule retentivity, adoption of species by farmers is very low. So, best long-linted G. arboreum genotypes with high yielding potential and suitable sowing time will be identified for rainfed tracts of cotton cultivated areas in India. Results The pooled analysis results found that the significantly highest mean seed cotton yield was recorded with Phule Dhanwanthry (1069 kg/ha) which was on par with K12 (1027 kg/ha), DLSA 17 (977 kg/ha) and PA 812 (951 kg/ha). Planting at 4 August yielded the significantly higher seed cotton yield (1345 kg/ha) in comparison with 4 September sowing (536 kg/ha). The interaction results in pooled data revealed that Genotype PA 812 planted at 4 August registered the significantly highest seed cotton yield (1487 kg/ha) which was on par with all genotypes sown on 4 August except PA 402. Amongst long-linted genotypes, PA 760 recorded the significantly highest upper half length (29.9 mm), mean length (24.9 mm) and fibre strength (27.0 g/tex) and fibre quality index (349.7); which was on par with DLSA 17, PA 812 and PA 402. The quality characters had not been influenced significantly by different times of sowing. Conclusions The results concluded that the significantly highest mean seed cotton yield was recorded with Phule Dhanwanthry (1069 kg/ha) which was on par with K12 (1027 kg/ha), DLSA 17 (977 kg/ha) and PA 812 (951 kg/ha). Planting at 4 August found that the significantly higher seed cotton yield (1345 kg/ha) in comparison with 4 September sowing (536 kg/ha). Amongst long-linted genotypes, PA 760 recorded the significantly higher fibre quality index (349.7)

“…In India commercial exploitation of hybrid vigor in cotton was mainly achieved and popularized by cultivation of Hybrid-4 and Varalaxmi at large scale [84]. Improvement in fiber quality, increased number of bolls, halo length and span length of cotton by heterosis were observed [85]. Combining ability generated larger progenies harboring new combinations by hybridization [86].…”

Cotton is considered as a major cash crop of the world. It earns huge foreign exchange by its valuable products; fiber, lint, cotton seed oil, hull and a lot more. Being an important fiber crop, it earns huge foreign exchange by contributing to textile and seed oil industry. This review summarizes cotton biology, its diversity and domestication, genome assembly, constraints in its production and methods to improve cotton plant to fulfill the need of textile and oil industry. But cotton is facing enormous biotic and abiotic stresses with insect pests being most prominent. Massive destruction caused by insects needs to be controlled for maintaining fruitful cotton crop production. Conventional breeding approaches are limited to improving single trait and integrate stable genes within plant genome in approximately 7-8 years. Improved biotechnological procedures have paved new pathways to target genes specifically and improve cotton germplasm in lesser time than conventional breeding.

“…Due to these contrasting relationships between plant height and yield, the correlation between height and cotton yield varies greatly in the literature. Several researchers proposed that plant height is negatively correlated with seed cotton yield [32][33][34][35][36], while some showed a positive correlation between them [7,9,30,37,38]. Also, some others have suggested no correlation between plant height and seed cotton yield [8,31].…”

“…In addition, data from the Northwest Inland Cotton region of China showed that the height of the first sympodial branch should exceed 20 cm to reduce the intake of residual plastic mulch which is widely used for cotton production in China. Other cotton plant architecture attributes such as height to node ratio (i.e., the internode length), and length of sympodial branches have direct and/or indirect effect on cotton yield and harvest efficiency [7][8][9][10][11]. However, there is little information on the effects of more detailed plant architectural attributes such as the length of all mainstem internodes and all fruiting branches on yield.…”

Mechanical harvesting has become inevitable for cotton production in China due to the rising labor cost in the country. It usually requires a moderate plant height and compact plant architecture. Correlation and stepwise regression were employed to analyze databases of our 24 field experiments between 2010 and 2017 in Hebei Province. The purpose is to identify the relationships between plant architecture traits and seed cotton yield within natural plant height range (58.6–163.2 cm) or preferred plant height range (80–120 cm) for mechanical harvesting in the Yellow River Valley of China, and define some important factors affecting seed cotton yield. Under natural plant height range across all experiments, there was a significantly negative correlation (r= −0.452) between plant height and yield. On limited plant height range desired for mechanical harvesting, the degree of this negative correlation decreased to r= −0.366. The correlation of plant height with seed cotton yield varied greatly with year, cultivar, plant density and mepiquat chloride (MC) application. Moreover, stepwise regression analysis picked internode length of the 1st (generally including 1st–7th mainstem node from bottom), 2nd (8th–12th node) and 4th (above 17th node) mainstem section and the length of lower fruiting branch (LFB) as significant factors influencing seed cotton yield under plant height range of 80–120 cm. The results have implications for precise control of cotton plant architecture preferred for mechanized harvesting in China.
