What is plant tissue culture? Write applications of tissue culture in agriculture?

Question

Ghissu Editorial · Accepted Answer

Plant tissue culture is the aseptic growing of plant cells, tissues or organs on a controlled nutrient medium, relying on cells' ability to regenerate whole plants. In agriculture it yields virus-free planting material through meristem culture, multiplies elite varieties by micropropagation and aids germplasm conservation and breeding.

**Introduction**

Plant tissue culture is a key biotechnology for rapid, disease-free⟦1⟧ plant propagation, addressing challenges like pest infestations and slow crop multiplication. Initiatives such as the Clean Plant Programme highlight its growing importance in India’s agricultural development by providing quality planting material to farmers.

**Understanding Plant Tissue Culture**

2. **Limitations and Cost Factors**: High costs and lack of standardized protocols for crops like mango and coconut limit scalability, especially in ==Andhra Pradesh==. Additionally, infrastructure gaps and technical complexities restrict widespread adoption beyond high-value crops.

**Applications of Tissue Culture in Agriculture**

1. **Disease-Free Material and Elite Varieties**: Meristem culture produces virus-free plants vital for sugarcane, potato, and banana, preventing pest and disease accumulation. Micropropagation supports rapid multiplication of superior cultivars, benefiting ==Andhra Pradesh== horticulture by meeting demand for quality planting material.

2. **Germplasm Conservation and Breeding**: Tissue culture aids genetic resource preservation and breeding of climate-smart varieties like drought-tolerant chickpea approved by the Central Sub-committee on Crop Standards⟦2⟧. It also facilitates doubled haploid production and genetic transformation, accelerating crop improvement.

**Way Forward**

1. **Expand Clean Plant Programme**: Accelerate establishment of Clean Plant Centres in ==Andhra Pradesh== to supply affordable, disease-free seedlings, enhancing horticultural productivity and farmer incomes.

2. **Promote Partnerships and Training**: Foster public-private collaboration to scale tissue culture infrastructure and reduce costs. Implement farmer education and extension programs in ==Andhra Pradesh== to improve awareness and adoption of tissue-cultured plants.

**Conclusion**

Plant tissue culture, combined with schemes like the Clean Plant Programme and supported by regional research and infrastructure, can significantly enhance agricultural productivity, sustainability, and resilience, contributing to the goals of SDG 2 and inclusive rural development.
