Abstract

The herbicide-tolerant rice cultivar designated ‘CL152’ and its hybrids and derivatives are disclosed.

First claim

What is claimed:

1. A rice plant of the variety ‘CL152,’ a representative sample of seeds of said variety having been deposited under ATCC Accession No. PTA-11753; or an F 1 hybrid of the variety ‘CL152’.

2. A method for producing rice plants, said method comprising planting a plurality of rice seeds of the rice plant of claim 1 , or a plurality of rice seeds capable of producing said rice plant, under conditions favorable for the growth of rice plants.

3. The rice plant of claim 1 , wherein said rice plant is a rice plant of the variety ‘CL152’.

4. A rice seed of the variety ‘CL152,’ a representative sample of seeds of said variety having been deposited under ATCC Accession No. PTA-11753; or a rice seed capable of producing the rice plant of claim 1 .

5. The method of claim 2 , additionally comprising the step of applying herbicide in the vicinity of the rice plants to control weeds, wherein the herbicide normally inhibits acetohydroxyacid synthase, at levels of the herbicide that would normally inhibit the growth of a rice plant.

6. The method of claim 5 , wherein the herbicide comprises a sulfonylurea.

7. The method of claim 5 , wherein the herbicide comprises an imidazolinone.

8. The method of claim 5 , wherein the herbicide comprises imazethapyr or imazamox.

9. Pollen of the plant of claim 1 .

10. An ovule of the plant of claim 1 .

11. A rice seed of the rice plant of claim 3 , or a rice seed capable of producing said rice plant.

12. A tissue culture of regenerable cells or protoplasts produced from the rice plant of claim 1 .

13. The tissue culture of claim 12 , wherein said cells or protoplasts are produced from a tissue selected from the group consisting of embryos, meristematic cells, pollen, leaves, anthers, roots, root tips, flowers, seeds, and stems.

14. A method of producing an insect resistant rice plant, said method comprising transforming the rice plant of claim 1 with a transgene that confers insect resistance.

15. An insect resistant rice plant produced by the method of claim 14 .

16. A method of producing a disease resistant rice plant, said method comprising transforming the rice plant of claim 1 with a transgene that confers disease resistance.

17. A disease resistant rice plant produced by the method of claim 16 .

18. A method of producing a rice plant with modified fatty acid or modified carbohydrate metabolism, said method comprising transforming the rice plant of claim 1 with at least one transgene encoding a protein selected from the group consisting of fructosyltransferase, levansucrase, alpha-amylase, invertase, and starch-branching enzyme; or encoding an antisense sequence to stearyl-ACP desaturase.

19. A rice plant having modified fatty acid or modified carbohydrate metabolism, wherein said rice plant is produced by the method of claim 18 , or a rice seed capable of producing said rice plant.

20. A method of introducing a desired trait into rice cultivar ‘CL152’, said method comprising the steps of:
(a) crossing the plant of claim 1 with a plant of another rice line expressing the desired trait, to produce progeny plants;
(b) selecting progeny plants that express the desired trait, to produce selected progeny plants;
(c) crossing the selected progeny plants with plants of rice cultivar ‘CL152’ to produce new progeny plants;
(d) selecting the new progeny plants that express both the desired trait and some or all of the physiological and morphological characteristics of rice cultivar ‘CL152’ to produce new selected progeny plants; and
(e) repeating steps (c) and (d) three or more times in succession to produce selected higher generation backcross progeny plants that express both the desired trait and essentially all of the physiological and morphological characteristics of rice cultivar ‘CL152’ as described in the VARIETYDESCRIPTION INFORMATION of the specification, determined at a 5% significance level, when grown in the same environmental conditions; and wherein the selected plants express the imidazolinone herbicide resistance characteristics of ‘CL152’.

21. The method of claim 20 , additionally comprising the steps of: (a) planting a plurality of rice seed produced by the selected higher generation backcross progeny plants under conditions favorable for the growth of rice plants; and (b) applying herbicide in the vicinity of the resulting rice plants to control weeds, wherein the herbicide normally inhibits acetohydroxyacid synthase, at levels of the herbicide that would normally inhibit the growth of a rice plant.

22. The method of claim 21 , wherein the herbicide comprises an imidazolinone.

23. The method of claim 21 , wherein the herbicide comprises imazethapyr or imazamox.

24. The seed of claim 4 , wherein said seed is treated with an AHAS-inhibiting herbicide.

25. The seed of claim 24 , wherein the AHAS-inhibiting herbicide comprises a herbicidally effective imidazolinone.

26. The seed of claim 24 , wherein the AHAS-inhibiting herbicide comprises a herbicidally effective sulfonylurea.

27. The method of claim 21 , wherein the herbicide comprises a sulfonylurea.

28. A product comprising the rice plant of claim 1 or a part thereof.
