Organic plant breeding contributes to the organic farming goals such as the work in accordance with biological systems and to have a positive impact on biodiversity â as organic breeders work with a broader genetic base than conventional breeders.

- 7. PBG-511 Introduction Objectives OPB Applications How do OPB improves Quality? Organic Plant Breeding How does OPB Improve Quality? Organic plant breeding improves the quality of plants by focusing on natural selection and genetic diversity rather than relying on chemical inputs or genetic modification. This results in plants that are better adapted to their environment and are more resistant to pests and diseases. Additionally, organic plant breeding often emphasizes the development of plants with improved nutritional content and taste.

Scope in Pakistan Organic Plant Breeding Scope in Pakistan Organic plant breeding has a significant scope in Pakistan as the country has a diverse range of agro-ecological zones that provide ideal conditions for growing a wide variety of crops. Pakistan has a strong tradition of small-scale, family-based farming, which makes it well-suited for the adoption of organic farming methods. Additionally, there is a growing demand for organic products both domestically and internationally, which presents an opportunity for Pakistani farmers to tap into this market. However, the actual implementation of organic plant breeding in Pakistan is still limited. The country does not have a comprehensive and well-funded research program for organic plant breeding. There are some research projects being conducted by universities and non-governmental organizations, but they are mostly limited in scale and not well-coordinated. Additionally, there is a lack of trained personnel and facilities to support organic plant breeding.

Recent Work Organic Plant Breeding Recent Work on OPB Organic plant breeding is an ongoing process and research in this field is constantly evolving. Here are a few examples of recent work on organic plant breeding: A study published in 2020 by researchers from the University of California, Davis and the USDA's Organic Agriculture Research and Extension Initiative, found that organic plant breeding can result in higher crop yields and improved plant health compared to conventional breeding methods. In 2020, a team of researchers from the University of Copenhagen published a study in which they identified genetic markers for plant resistance to powdery mildew in barley. These markers can be used in organic plant breeding to develop disease-resistant barley varieties. In 2019, a study by researchers at the Norwegian University of Life Sciences found that organic plant breeding can lead to the development of crops with improved nutritional content. They found that organically grown barley had higher levels of antioxidants and minerals than conventionally grown barley.

Organic varieties helps in reducing the cost of cultivation by avoiding the use of various agrochemicals. Ecofriendly. Permits multiplication of natural enemies of harmful insects resulting in effective biological control. More emphasis is given on improvement of quality rather than yield. Use of chemicals is prohibited. Insecticides will not reach the food chain. Beneficial soil microflora will increase and ground water and rain water will be free from contamination of chemicals. Use of organic varieties will lead to sustainable agriculture. promotes use of biological inputs such as organic manures, botanical pesticides which do not have any adverse effect on the ecosystem.

Objectives OPB Application Advantag es Disadvantages Organic Plant Breeding Disadvantages Banning use of induced mutation technique will have adverse effect on progress of OPB. Banning of Protoplasm Fusion technique will act as a barrier in somatic hybridization. The breeding efficiency will go down and breeding will be more expensive. Restriction on the exchange of materials between traditional and organic breeding will have adverse effect in the progress of OPB. Banning of useful techniques/chemicals such as Tissue culture techniques, GMO and colchicine will prolong the period of developing organic varieties.

Disadvanta ges Introductions Objectives OPB Techniques Advanta ges Conclusions Organic Plant Breeding Conclusions Organic plant breeding varies to accommodate different sets of conditions and needs. These include differences in regional growing conditions (such as varieties of insects, diseases, and weeds) and different fertility issues. Many conventional crops are bred to withstand cross-country or even international shipping. To serve niche markets, local markets, and health-conscious consumers, organic breeders can select for higher nutrition or enhanced flavor, rather than how well seeds survive shipment. When bred for these traits, organic farmers gain unique varieties that are designed to thrive in organic growing conditions.
