Abstract
An inbred sunflower line, designated CN1703, the plants and seeds of the inbred sunflower line CN1703, methods for producing a sunflower plant, either inbred or hybrid, produced by crossing the inbred sunflower line CN1703 with itself or with another sunflower plant, and hybrid sunflower seeds and plants produced by crossing the inbred line CN1703 with another sunflower line or plant and to methods for producing a sunflower plant containing in its genetic material one or more transgenes and to the transgenic sunflower plants produced by that method. This invention also relates to inbred sunflower lines derived from inbred sunflower line CN1703, to methods for producing other inbred sunflower lines derived from inbred sunflower line CN1703 and to the inbred sunflower lines derived by the use of those methods.
Claims61
A seed of sunflower inbred line designated CN1703, or a part thereof, a representative sample of the seed having been deposited under ATCC Accession No. PTA-6885.
A method for producing an inbred sunflower plant, comprising:
- (a) crossing inbred sunflower plant CN1703, a representative sample of seed of the plant having been deposited under ATCC Accession No. PTA-6885, with another different sunflower plant to yield a F1 progeny sunflower plant;
- (b) harvesting seed from the F1 progeny sunflower plant;
- (c) growing the F1 progeny sunflower seed from step (b) under self-pollinating or sib-pollinating conditions for about 5 to about 7 generations to produce inbred sunflower plants;
- (d) selecting the plants of step (c) for a desirable trait.
A method of introducing a desired trait into sunflower inbred line CN1703 comprising:
- (a) crossing CN1703 plants grown from CN1703 seed, a representative sample of the CN1703 seed having been deposited under ATCC Accession No. PTA-6885, with plants of another sunflower line that comprise a desired trait to produce F1 progeny plants;
- (b) selecting F1 progeny plants that have the desired trait;
- (c) crossing selected progeny plants with CN1703 plants to produce backcross progeny plants;
- (d) selecting for backcross progeny plants that comprise the desired trait and physiological and morphological characteristics of sunflower inbred line CN1703;
- and
- (e) performing steps (c) and (d) one or more times in succession to produce the selected or higher backcross progeny plants that comprise the desired trait and all of the physiological and morphological characteristics of sunflower inbred line CN1703 listed in Table 1 as determined at the 5% significance level when grown in the same environmental conditions.
A method for producing an inbred sunflower plant, comprising:
- a) growing first generation hybrid sunflower plants having a parent sunflower plant grown from CN1703 seed, a representative sample of the seed having been deposited under ATCC Accession No. PTA-6885;
- b) inbreeding the first generation hybrid sunflower plants or crossing the first generation hybrid sunflower plants with different sunflower plants to yield progeny sunflower seed;
- c) growing the progeny sunflower seed of step b) to yield further progeny sunflower seed;
- d) repeating the inbreeding or the crossing and the growing steps of b) and c) from about 1 to about 7 times to generate inbred sunflower plants.
A method for producing a CN1703-derived sunflower plant, comprising:
- a) crossing inbred sunflower line CN1703, representative seed of the line having been deposited under ATCC Accession No. PTA-6885, with a second sunflower plant to yield progeny sunflower seed;
- and
- b) growing said progeny sunflower seed, under plant growth conditions, to yield said CN1703-derived sunflower plant.
A method for regenerating a sunflower plant comprising the steps of:
- (a) culturing an explant comprising a tissue selected from the group consisting of a tissue obtained from inbred sunflower plant CN1703, a representative sample of seed of the plant having been deposited under ATCC Accession No. PTA-6885, an immature tissue obtained from a hybrid sunflower plant having CN1703 as a parent, and a CN1703-derived sunflower plant;
- and,
- (b) initiating regeneration.
A method for developing a sunflower plant in a sunflower plant breeding program, comprising:
- a) utilizing the inbred sunflower plant CN1703, a representative sample of seed having been deposited under ATCC Accession No. PTA-6885 [genetic marker dataset in Table 3].
