In 2002, Bt Cotton became the first and only transgenic crop approved by the GEAC for commercial cultivation in six States namely, Andhra Pradesh, Gujarat, Karnataka, Madhya Pradesh, Maharashtra, and Tamil Nadu. The concept of changing a crop’s genes is not new technology at all. However, there are many other crops, including other cereal grains and a number of vegetables and fruits that have been improved using genetic engineering and are in the commercialization pipeline (Table 1). • Having a -carotene (precursor of Vit-A) rich rice. GM crops are developed by a process of genetic modification by which selected individual genes are inserted from one organism into another (i.e. The below mentioned article provides notes on genetic engineering of crops. • Varieties developed by DRMR are: NRC-HB-506 (first hybrid mustard in India). Improvements can be achieved in much shorter time frames. 3. One has approach a third party certification agency, and wait for one to three years to obtain an organic certificate. They also have improved tolerance to cold/heat, drought and salinity. In addition, genetically engineered crops are required to undergo extensive food and environmental safety assessment, whereas conventionally modified crops are not. A single gene encoding an insecticidal protein from Bacillus thuringiensis (Bt) was transferred into corn. • Bacillus thuringensis is a soil bacterium that produces proteins lethal to insect larvae affecting the digestive system of boll worms. The government must not allow field trials of GM crops till there is a strong, revamped, multi-disciplinary regulatory system in place.The Committee studied the regulatory system in different countries and found that the one in Norway is the best. When we talk about genetically modified crops, we must begin by clarifying that all the plants that are grown today in the world have been modified by the man using different mechanisms that allow them to select characteristics according to their needs. DDA Sectional Officer Horticulture Syllabus Exam Pattern Horticulture Notes, General Agriculture MCQ With Explanation-67. They can reduce species diversity. • These are glyphosate resistance mustard developed by Pro- . Unchecked import of GM products should be stopped. GM crops have improved resistance to diseases, pest, insects and herbicides. Almost all of the world’s major crops are now being improved using genetic engineering, although initial efforts have focused on commodity crops-primarily corn, soybeans, cotton, canola and potatoes. It looks into approval for large scale releases and commercialization of the GMOs, State Biotechnology Coordination Committee (SBCC). This cannot be achieved without technology. The Bt gene confers resistance to the European corn borer, a devastating insect pest. In 2017, the Genetic Engineering Appraisal Committee recommended the commercial approval of the HT Mustard crop. FDA has approved 51 different products that are in various stages of commercialization. It is genetically modified variety of Herbicide Tolerant (HT) mustard. This improves how long they last and stay fresh during transportation and storage. This would ensure trust in the entire process. A major challenge today is to develop low-input, high-output agriculture. The technology is often called ‘gene technology’, or ‘recombinant DNA technology’ or ‘genetic engineering’ and the resulting organism is said to be ‘genetically modified’, ‘genetically engineered’ or ‘transgenic’. MGR1(earlier named as CoRH-1) developed first by TNAU, Coimbatore and PRH-1 & P14II-6 developed by JAR!. Cotton and potato crops receive extensive pesticide treatment in the United States, and use of the genetically modified varieties results in a reduction in pesticides. In order to meet the nutritional needs of this growing population, cereal production alone will need to increase by 40% in the next 20 years. Cotton varieties developed by Mahyco: MECH-12, MECH-162, MFCH-184 for Southern States and RCH-134, RCH-138 suitable for Northern India. Cotton developed against cotton boll, • Bacillus thuringensis is a soil bacterium that produces proteins lethal to insect larvae affecting the digestive. The safety aspects of genetically modified crops are assessed by the Institutional Biosafety Committees (IBSCs), Review Committee on Genetic Manipulation (RCGM) and Genetic Engineering Appraisal Committee (GEAC) constituted under Rules 1989 of Environment Protection Act (EPA) – 1986 based on Biosafety Guidelines and the Standard Operating Procedures. Hybrid Mustard: (Genetically Modified Crops), • Developed by DRMR (Directorate of Rapeseed and Mustard Research), Bharatpur (Rajasthan). One of the first products of plant biotechnology was insect resistant corn. The first genetically modified crops were commercially grown in 1996. Genetically modified foods have a longer shelf life. It has failed as a sustainable agriculture technology and has, therefore, also failed to provide livelihood security for cotton farmers who are mainly resource-poor, small and marginal farmers. To access the same, a google account is a must. Forty per cent of the world’s land use for agriculture is already seriously degraded. Re-evaluation of all research findings in Bt cotton seeds in the light of studies that highlighted inexplicable changes in the organs and tissues of Bt-cotton seed-fed lambs. Genetic engineering is improving the quality (nutrition) and yield of crop plants and livestock --> therefore is solving the demand for food in the world 1. The Indian government must take decisions on GM technologies on the basis of scientific evidence. Weeds growing in pea fields are harvested along with the peas. The crops in which one or many of its traits are altered or enhanced through a process of genetic engineering known as GM crops i.e. As of 2014, genetically modified crops occupied 448 million acres globally, representing a global market value of 15.7 billion dollars. The Maharashtra Hybrids Seed Company (Mahyco) jointly with the US seed company Monsanto developed the genetically modified Bt Cotton to tackle the bollworm problem that had devastated cotton crops in the past. Dhara Mustard Hybrid(DMH-11) is an indigenously developed transgenic mustard. Potential impact on human health including allergens and transfer of antibiotic resistance markers. Genetic engineering of crops became available in the early 1980’s as genetic engineering techniques were being perfected. An additional benefit of Bt corn is that, because the worms cannot form holes in the corn, fungi that can produce toxic mycotoxins, e.g., fumonisin, cannot attack the corn, resulting in a cleaner, safer product. This time has been cut in half using the tools of genetic engineering. When these berries are thermally processed along with the peas, the berries harden and are highly unacceptable to consumers. These rules and regulations cover the areas of research as well as large scale applications of the GM crops. Consumers typically throw away ears of sweet corn if they find worms, even though the heavy use of pesticides assures that the worms do not survive more than about an inch down the cob. The second major area of genetic modification is herbicide tolerance. Mechanism to allow cultivation of GM crops in India: Important Committees and Recommendations: Task Force under the Chairmanship of Prof. M.S. CLICK TO DOWNLOAD=>  Agri Exam Important Agriculture Mcq Pdf Download. The Food and Agriculture Organization (FAO) has rightly pointed out in 2004, “Science cannot declare any technology completely risk free. It does not result in high yields as promised. One of the most valuable aspects of these products from an environmental perspective is that they encourage “no till” farming methods, which significantly reduce soil erosion. Technology that has the ability to remove undesired and add desired traits to an organism, must have some major advantages and disadvantages for humankind. We simply cannot achieve the kinds of yield increases in a sustainable way using traditional methods of breeding. Farmers have recognized the benefits of crop biotechnology and have readily adopted it. Variety Bollgourd-1, using Cry -I Ac gene. The initiative was blocked in 2010. There is only a Food Lab in Kolkata under the Ministry of Health and which is not well-equipped. It was developed by Mahyco (Maharashtra Hybrid Seeds Company) in collaboration with the Dharward University of Agricultural Sciences and the Tamil Nadu Agricultural University. Farmers have a hard time eliminating nightshade from their pea fields; herbicide tolerant sweet peas would simplify weed control and improve final product quality. bacterial gene into cotton) to enhance desirable characteristics (‘traits’) or to suppress undesirable ones ( i.e. Mandatory labelling of products from GM crops. The paper notes that GE (genetically engineered) Bt cotton has failed in India. Concerns over transparency: GEAC’s refusal to publicly release the safety testing data submitted for regulatory approval of BT Brinjal and GM Mustard, until GM opponents filed a Right to Information petition has raised serious questions over transparency.The tendency to operate in secrecy has created a serious distrust on the government and the promoters of GM crops. The paper also raises questions on the genetic engineering technology itself on the grounds that it raises the cost of sowing. • The gene responsible for this effect is Cry-lAc. }, Golden Rice: (Genetically Modified Crops). The regulatory regime in India with regard to the GM crops has never been assessed thoroughly with regard to the GM risk assessment in Indian conditions. • The position of transgenic plants in world (in area): Soyabean (> 60 %) > Maize > Cotton > Canola. The leaves of conventional potato plants are almost totally denuded by the Colorado potato beetle, and this lowers crop yields. Although the European corn borer and corn earworm have the word “corn” in their names, they affect many other vegetables, such as green beans and peppers. Conventional breeding involves random mixing of the tens of thousands of genes present in a plant with the ten of thousands of genes present in another plant. We use cookies to ensure that we give you the best experience on our website. According to critics, the current safety assessments are inadequate to catch most of the harmful effects from the GM crops. GM technology could also allow the transfer of genes from one crop to another, creating “super weeds”, which will be immune to common control methods. The same Bt gene in field corn can be transferred into other vegetables and confer resistance to those same, or related, insect pests. A thorough probe must be conducted into the permission given for the commercialisation of Bt Brinjal right from the beginning till a moratorium was imposed in 2010. We ask students to login via google as we share a lot of our content over google drive. Virus resistance is achieved through the introduction of a gene from certain viruses which cause disease in plants. Bt. Genetically Modified Organisms are the ones in which the genetic material (DNA) has been altered in such a way as to get the required quality. Adoption of this technology would result in a higher quality product and significant reduction in the use of pesticides. on Genetically Modified Organisms – Comprehensive Notes, 19th January 2018 | Prelims Daily with Previous Year Questions, 2 days left to join our January Batches – Tests and Classes to start. Use of these crops has resulted in environmental and food safety benefits, including a significant 2.7 million pounds per year reduction in the use of pesticides, and modelling studies indicate that ground water contamination by herbicides can be significantly reduced when glyphosate tolerant crops are planted. It was created by using “barnase/barstar” technology for genetic modification by adding genes from soil bacterium that makes mustard self-pollinating plant. The Bt gene has been transferred into potatoes to confer resistance to the Colorado potato beetle, a devastating pest in potatoes.
