Study Notes
Traditional Breeding Techniques
- Selection: Choosing plants with desirable traits for reproduction.
- Cross-breeding: Mating different plant varieties to create offspring with combined traits.
- Hybridization: Producing hybrids from two parent strains to enhance characteristics such as yield and disease resistance.
- Backcrossing: Repeatedly crossing a hybrid with one of its parents to reinforce specific traits.
- Grafting: Joining plant parts from different varieties to propagate new traits.
Objective of Plant Cell Tissue Culture
- To study and apply techniques for growing plant cells or tissues in controlled environments.
- Aims to mass-produce genetically uniform plants and preserve endangered species.
- Facilitates research in plant genetics and pathogen resistance.
Plant Biotechnology
- Involves the use of technology to manipulate plant cells and gene expression.
- Encompasses genetic engineering, molecular marker-assisted selection, and tissue culture.
- Aims to improve crop yield, enhance nutritional value, and develop pest-resistant varieties.
