Improving the nutritional content of plants by increasing vitamins and minerals.

The complex interaction between genes and the traits they control, especially in plants with multiple sets of chromosomes.

Breeding new plant varieties can take many years of testing and evaluating in different environments.

Ensuring that new plant varieties are resistant to diseases and pests.

Creating crops that can withstand extreme weather conditions like drought or floods.

Using advanced tools and techniques to accelerate the plant breeding process.

Predicting how plant traits will change in different environments.

Developing new plant varieties that use fewer resources like water and fertilizer.

The art and science of improving plants for human benefit. It involves manipulating plant genes to enhance desirable traits like yield, quality, disease resistance, and adaptation to environmental conditions.

Selecting plants with desirable traits to use as parents for future generations.

Breeding plants, often different varieties, together to create offspring with traits from both parents.

Repeatedly crossing a hybrid plant with its parent to reintroduce desirable genes from the parent into the hybrid, creating a stable new variety.

Inducing mutations in plants using radiation or chemicals, then selecting for beneficial changes.

Using DNA markers associated with specific traits to identify desirable genes in breeding programs, speeding up the process of finding the best plants.

Introducing foreign genes into a plant to modify its traits, often to improve resilience, yield, or nutritional value, using methods like CRISPR-Cas9.

Determining the entire DNA sequence of a plant, allowing for a deeper understanding of its genetic makeup and faster breeding.
