Maize Germplasm for a Dominant Dwarfing Trait
A dominant dwarfing maize mutant, D16, can be used to breed short-statured corn, reducing losses from green snap and stalk lodging.
Researchers at Purdue University have generated a dominant dwarfing maize mutant in B73 maize inbred called mutant D16. D16 can be used as a source of germplasm to breed for short-statured corn, providing the advantages associated with shorter corn, including less green snap and stalk lodging. A D16 homozygote is approximately 50% of the height of normal B73 maize, with the heterozygote being 65-70% as tall as normal B73.
Advantages:
-Shorter corn
-Less green snap and stalk lodging
Potential Applications:
-Agriculture
Technology Validation:
A D16 homozygote is approximately 50% of the height of normal B73 maize, with the heterozygote being 65-70% as tall as B73.
