“…Cotton (Gossypium hirsutum L.) is one of the most important commercial crop plants grown worldwide for fiber and seeds. India is the second largest cotton producer contributing to approximately 22% of the world production (Directorate of Cotton Development Government of India, 2017; Mohapatra and Saha, 2019). Weeds are one of the very many factors that negatively challenge productivity of cotton accounting to approximately 50-85% of yield losses (Jain et al, 1981;Frisvold et al, 2009;Ayyadurai and Poonguzhalan, 2011;Awan et al, 2015;Ramachandra et al, 2016).…”

Weeds burden plant growth as they compete for space, sunlight, and soil nutrients leading to 25-80% yield losses. Glyphosate [N-(phosphonomethyl)glycine] is a widely used broad spectrum non-selective herbicide that controls weeds by inhibiting 5enolpyruvylshikimate-3-phosphate synthase (EPSPS) enzyme and interfering with the shikimate biosynthesis pathway. Cotton (Gossypium hirsutum L.) is one of the most important commercial crops grown worldwide for its fiber. We have developed herbicide tolerant transgenic cotton (cv. P8-6) by introgression of a codon-optimized and modified EPSPS gene (CP4-EPSPS) possessing an N-terminal chloroplast targeting peptide from Petunia hybrida. Because of the recalcitrant nature of cotton, a genotype-independent non-tissue culture-based apical meristem-targeted in planta transformation approach was used to develop transformants. Although in planta transformation methodologies are advantageous in developing a large number of transgenic plants, effective screening strategies are essential for initial identification of transformants. In the present study, the use of a two-level rigorous screening strategy identified 2.27% of T1 generation plants as tolerant to 800 and 1,500 mg/L of commercially available glyphosate (Roundup). Precise molecular characterization revealed stable integration, expression, and inheritance of CP4-EPSPS in advanced generations of the promising transgenic events. Further, superiority of selected transgenic plants in tolerating increasing levels of glyphosate (500-4,000 mg/L) was ascertained through reduced accumulation of shikimate. This report is the first of its kind where cotton transformants tolerating high levels of glyphosate (up to 4,000 mg/L) and accumulating low levels of shikimate have been identified. This study not only reiterated the genotype-independent nature of the transformation strategy but also reiterated the translational utility of the CP4-EPSPS gene in management of weeds.

“…The nation produces the largest lot of conventional Cotton next to China comprising. India also is a global leader in organic cotton production catering to 70% of total global demands (Mohapatra & Saha, 2019). It is therefore important for country like India, which lacks proper crop-grain storage, maintenance, effective transportation, logistics, to have real-time data of production and distribution (Rajendran, 2003) with an effective boost in infrastructure that has a direct implication on the production of Cotton (Chinnadurai, Sangeetha, Anbarassan & Kavitha, 2019).…”

The paper attempts forecasting the Cotton Growth area in Punjab and Haryana using the best fitted Auto-Regressive Integrated Moving Average (ARIMA) model. The time series data on area growth of cotton in Punjab and Haryana for the period of last 10 Years i.e. from 2012-13 to 2021-22 is analyzed for this study. The best models are selected by calculating Normalized BIC; Mean Absolute Percentage Error (MAPE) and maximum values of R . The study revealed that ARIMA (1,1,1) and ARIMA (0,1,1) are the best fitted models for forecasting Growth area of cotton in both states. The analysis shows an increasing trend in area of cotton for both the states Punjab and Haryana.

“…Sustainable agriculture is the need of the hour in the context of global and liberalization trends. Crop production encounters various biotic and abiotic stresses particularly in the arid and semiarid regions (Mohapatra and Saha, 2019). Cotton is a major fibre crop of global importance and has high commercial value.…”

Cotton (Gossypium spp.), is a mercantile crop plant is grown for its fluffy fiber and cotton seed oil in around 70 countries worldwide. Cotton is an economically important crop, shows erratic productivity under rain feed conditions; it is bogged down with many biotic and abiotic stresses. Due to lack of resistant germplasm, crop improvement through conventional breeding practices has been lagging. Genetic engineering offers numerous protocols to engineer plants to overcome stress. Biotechnological intervention for cotton improvement has begun three decades ago. The recalcitrance of cotton to tissue culture has been the major constraint for in vitro regeneration. Alternate methods that evade tissue culture regeneration steps have thus been envisaged. Till date there are very few standardized protocols that can be employed to develop transgenics in a genotype independent manner. Thus, genotype independent in planta transformation strategies have gained momentum in the present days, but reproducibility of reported protocols remains an amigna in many cases. In planta transformations holds prominence due to viability and ease in generation of transgenic cotton plants with in less time. This review focuses on grouping efforts made by different research groups in this senior. Several reports and standardizations have been focused that reports development of transgenic cotton.
