10 Questions
What is mutation breeding?
The purposeful application of mutations in plant breeding.
How are mutations induced?
Through chemical, physical, or biological agents.
What are the two major steps in identifying individuals with a target mutation?
Screening and confirmation
What type of mutations are important in crop improvement?
Mutations involving single bases.
What are point mutations?
Mutations involving the replacement of a single nucleotide with a different one
Why are induced mutations preferred over spontaneous mutations in breeding?
Induced mutations offer a more direct approach to obtain desirable and economically beneficial traits during breeding.
How can mutations be induced?
Through the use of chemical and physical mutagens.
When does screening and selection start in mutation breeding?
M2 generation
What is the effectiveness of mutation breeding dependent upon?
The efficacy of selection of useful variant mutants.
What is the forward genetics approach?
An approach that works from traits (phenotypes) to genes.
