SUSTAINING AGRICULTURE
• Development and release of high-
yielding crop varieties
• Development of efficient crop
production and protection technologies
![Page 4: Biotech Farming by Dr. Manjit Singh Kang, Vice Chancellor, Punjab Agricultural University. Ludhiana](https://reader033.fdocuments.in/reader033/viewer/2022050801/55720aeb497959fc0b8c159d/html5/thumbnails/4.jpg)
SUSTAINING AGRICULTURE
• Use of quality agrochemicals (fertilizers, pesticides)
• Assured irrigation
• Developing crop varieties with greater water-use efficiency
![Page 5: Biotech Farming by Dr. Manjit Singh Kang, Vice Chancellor, Punjab Agricultural University. Ludhiana](https://reader033.fdocuments.in/reader033/viewer/2022050801/55720aeb497959fc0b8c159d/html5/thumbnails/5.jpg)
• Biotechnology provides powerful tools for the sustainable development of agriculture, fisheries and forestry, as well as the food industry. When appropriately integrated with other technologies, it can be of significant assistance in meeting the needs of an expanding and increasingly urbanized population in the next millennium. (FAO, 2000)

BIOTECHNOLOGY ASPECTS:
RELEVANCE TO AGRICULTURE
• Tissue culture/micropropagation
• Haploid/ doubled-haploid breeding
• Transgenic technology
• DNA-marker technology
![Page 7: Biotech Farming by Dr. Manjit Singh Kang, Vice Chancellor, Punjab Agricultural University. Ludhiana](https://reader033.fdocuments.in/reader033/viewer/2022050801/55720aeb497959fc0b8c159d/html5/thumbnails/7.jpg)
TISSUE CULTURE MICROPROPAGATION
Micropropagation involves the production of plants from very small (1 mm) plant parts through tissue culture. Micropropagation of selected ornamentals, field, fruit and forest plant species is one of the best and most successful examples of commercial applications of tissue-culture technology.
![Page 8: Biotech Farming by Dr. Manjit Singh Kang, Vice Chancellor, Punjab Agricultural University. Ludhiana](https://reader033.fdocuments.in/reader033/viewer/2022050801/55720aeb497959fc0b8c159d/html5/thumbnails/8.jpg)
APPLICATIONS OF MICROPROPAGATION
1. PRODUCTION OF SUPER-ELITE PLANTING MATERIAL (SEED) OF VEGETATIVELY PROPAGATED SPECIES.
2. QUICK SPREAD OF NEW VARIETIES OF VEGETATIVELY PROPAGATED SPECIES.
3. REJUVENATION OF OLD VARIETIES OF VEGETATIVELY PROPAGATED SPECIES.

SPREAD OF MICROPROPAGATION TECHNOLOGY
• More than 500 million plants belonging to different plant species are annually produced through micopropagation in the world.
• There are more than 100 commercial tissue-culture units in India
![Page 17: Biotech Farming by Dr. Manjit Singh Kang, Vice Chancellor, Punjab Agricultural University. Ludhiana](https://reader033.fdocuments.in/reader033/viewer/2022050801/55720aeb497959fc0b8c159d/html5/thumbnails/17.jpg)
HAPLOID/DOUBLED-HAPLOID
BREEDING
Production of haploids/doubled haploids through anther and pollen culture from F1 plants, and embryo culture from wide crosses is a very useful technique for shortening the breeding cycle and early release of varieties.
![Page 18: Biotech Farming by Dr. Manjit Singh Kang, Vice Chancellor, Punjab Agricultural University. Ludhiana](https://reader033.fdocuments.in/reader033/viewer/2022050801/55720aeb497959fc0b8c159d/html5/thumbnails/18.jpg)

APPLICATIONS
• In vitro production of haploids/doubled-haploids from F1 plants results in true-breeding plants in less than one year, which otherwise takes 7 to 8 generations through conventional methods.
• Several cultivars are either in tests or have been released in rice, wheat, maize, rapeseed and mustard in China, Canada, Denmark, USA and France.
![Page 21: Biotech Farming by Dr. Manjit Singh Kang, Vice Chancellor, Punjab Agricultural University. Ludhiana](https://reader033.fdocuments.in/reader033/viewer/2022050801/55720aeb497959fc0b8c159d/html5/thumbnails/21.jpg)
TRANSGENIC TECHNOLOGY
• Useful genes cloned from viruses, bacteria, fungi, insects, animals, human beings and even the genes synthesized in the lab can be introduced into plants.
• Unlike conventional plant breeding, only the specific, cloned gene (s) is (are) being introduced without the co-transfer of undesirable genes from donor. No need for repeated backcrossing.
