US 7,094,957 B2 · Hybrid maize 33D11

Abstract

A novel hybrid maize variety designated 33D11 and seed, plants and plant parts thereof, produced by crossing two Pioneer Hi-Bred International, Inc. proprietary inbred maize lines. Methods for producing a maize plant that comprises crossing hybrid maize variety 33D11 with another maize plant. Methods for producing a maize plant containing in its genetic material one or more traits introgressed into 33D11 through backcross conversion and/or transformation, and to the maize seed, plant and plant part produced thereby. This invention relates to the hybrid seed 33D11, the hybrid plant produced from the seed, and variants, mutants, and trivial modifications of hybrid 33D11. This invention further relates to methods for producing maize lines derived from hybrid maize variety 33D11 and to the maize lines derived by the use of those methods.

Dependent claims

A seed of hybrid maize variety designated 33D11, representative seed of said variety having been deposited under ATCC Accession No:

PTA-7005.

A process of introducing a desired trait into a hybrid maize variety 33D11 comprising:

(a) crossing at least one of inbred maize parent plants GE752309 and GE2120257, representative seed of which have been deposited under ATCC Accession Nos:
as PTA-7025 and PTA-7042 respectively, with plants of another maize line that comprise a desired trait to produce F1 progeny plants, wherein the desired trait is selected from the group consisting of male sterility, site-specific recombination, increased transformability and abiotic stress tolerance;
(b) selecting said F1 progeny plants that have the desired trait to produce selected F1 progeny plants;
(c) backcrossing the selected progeny plants with said inbred maize parent plant to produce backcross progeny plants;
(d) selecting for backcross progeny plants that have the desired trait and morphological and physiological characteristics of said inbred maize parent plant to produce selected backcross progeny plants;
(e) repeating steps (c) and (d) three or more times in succession to produce a selected fourth or higher backcross progeny plants;
and
(f) crossing said fourth or higher backcross progeny plant with the other inbred maize parent plant to produce a hybrid maize variety 33D11 that comprises the desired trait and all of the morphological and physiological characteristics of hybrid maize variety 33D11 listed in Table 1 as determined at the 5% significance level when grown in the same environmental conditions.
