Cotton transgenic event mon 88702 and methods for detection and uses thereof

A method of producing an insect resistant cotton plant comprising:

• a) sexually crossing two different cotton plants with at least one of the two different cotton plants comprising transgenic cotton event MON 88702 DNA;
• b) sampling seed or tissue from progeny of the crossing;
• c) detecting a sequence diagnostic for cotton event MON 88702 in said sample from step (b) to identify progeny comprising cotton event MON 88702 DNA;
• and
• d) selecting said progeny comprising cotton event MON 88702 DNA, wherein the progeny is an insect resistant cotton plant comprising transgenic cotton event MON 88702 DNA.

A method of determining the zygosity of a cotton plant or cotton seed comprising event MON 88702 comprising:

• a) contacting a sample comprising cotton DNA with a primer set capable of producing a first amplicon diagnostic for event MON 88702 and a second amplicon diagnostic for native cotton genomic DNA not comprising event MON 88702;
• i) performing a nucleic acid amplification reaction with the sample and the primer set;
• and
• ii) detecting in the nucleic acid amplification reaction the first amplicon diagnostic for event MON 88702, or the second amplicon diagnostic for native cotton genomic DNA not comprising event MON 88702,
• wherein the presence of only the first amplicon is diagnostic of a cotton plant homozygous for event MON 88702 DNA in the sample, and the presence of both the first amplicon and the second amplicon is diagnostic of a cotton plant heterozygous for event MON 88702 allele;
• or
• b) contacting a sample comprising cotton DNA with a probe set which contains at least a first probe that specifically hybridizes to event MON 88702 DNA and at least a second probe that specifically hybridizes to cotton genomic DNA that was disrupted by insertion of the heterologous DNA of event MON 88702 and does not hybridize to event MON 88702 DNA,
• i) hybridizing the probe set with the sample under stringent hybridization conditions, and
• ii) detecting hybridization of the first probe or the second probe, wherein detecting hybridization of only the first probe under the hybridization conditions is diagnostic for a homozygous allele of event MON 88702 DNA in the sample, and wherein detecting hybridization of both the first probe and the second probe under the hybridization conditions is diagnostic for a heterozygous allele of event MON 88702 in a DNA sample.
