Plant Breeding Methods

Click on the flashcard to see the answer

What is plant breeding?

Plant breeding is the science of changing the traits of plants to produce desired characteristics.

What is hybridization in plant breeding?

Hybridization in plant breeding is the process of cross-pollinating two genetically different plants to produce offspring with superior traits.

Describe the backcross method.

The backcross method involves crossing a hybrid with one of its parents to retain desirable traits of the parent.

What is mass selection in plant breeding?

Mass selection involves selecting plants with desirable traits en masse for the next generation.

What is pure-line selection?

Pure-line selection is selecting superior individuals from the progeny of a single self-pollinated plant.

Explain the process of mutation breeding.

Mutation breeding involves exposing plants to chemicals or radiation to induce genetic mutations that may result in desirable traits.

What is transgenic plant breeding?

Transgenic plant breeding involves inserting specific genes from any organism into a plant's genome to introduce new traits.

What are the advantages of polyploidy in plant breeding?

Polyploidy can increase genetic variation and result in plants with higher yields or enhanced qualities.

How does marker-assisted selection work in breeding?

Marker-assisted selection uses molecular markers linked to desired traits to assist in breeding selection.

What role does genomic selection play in modern plant breeding?

Genomic selection uses genome-wide scanning to predict and select plants with desirable traits based on genetic data.

What are the challenges facing plant breeding today?

Challenges include climate change impacts, limited genetic diversity, and sociopolitical barriers to genetic modifications.

Why is germplasm important in plant breeding?

Germplasm provides the genetic resources necessary for plant breeding to introduce new traits and variation.

What is the significance of bioinformatics in plant breeding?

Bioinformatics analyzes complex data sets to identify genetic markers and streamline breeding strategies.

Explain the concept of genetic linkage maps.

Genetic linkage maps illustrate the arrangement of genes on chromosomes and their relative recombination frequencies.

What is participatory plant breeding?

Participatory plant breeding involves farmers collaborating with scientists in the selection and breeding process.
