Abstract
This disclosure provides methods and compositions for identifying Brassica plants that have a native deletion of the INDEHISCENT gene (BnIND-A) located on chromosome A of B. napus. Also provided are methods of improving one or more agronomic characteristics such as pod shatter and breeding methods for introducing a pod shatter tolerant phenotype in Brassica plants and/or their progeny.
Claims14
A method of identifying a Brassica plant, cell, or germplasm thereof comprising a BnIND-A genomic deletion that contributes to a pod shatter tolerance phenotype, the method comprising:
- a. obtaining a nucleic acid sample from a Brassica plant cell, or germplasm;
- and
- b. screening the sample for genomic sequence comprising a deletion of the BnIND-A gene on chromosome N03, wherein the deleted genomic segment results in a breakpoint locus corresponding to positions 10,002-10,003 of SEQ ID NO:2, and wherein the BnIND-A deletion contributes to pod shatter tolerance phenotype in Brassica.
