Abstract

The present invention relates to an iceberg lettuce having one or more romaine lettuce characteristics. The invention further relates to methods for producing iceberg lettuce varieties containing one or more romaine lettuce characteristics.

Claims (30)

1. A lettuce seed capable of producing a lettuce plant, said lettuce plant comprising a head having an outer leaf comprising a leaf length to width ratio between about 1.2 and about 2.7 and at least one morphological characteristic of an iceberg lettuce type selected from the group consisting of crisp texture, bland taste, high water content, and firm density.

2. The lettuce seed capable of producing the lettuce plant of claim 1 , wherein said lettuce plant further comprises at least one morphological characteristic selected from the group consisting of an elliptical leaf stature, a spatulate leaf shape, and a semi open head formation.

3. The lettuce seed capable of producing the lettuce plant of claim 2 , wherein said lettuce plant comprises at least two of said morphological characteristics.

4. The lettuce seed capable of producing the lettuce plant of claim 1 , wherein said lettuce plant further comprises a head weight of at least 900 grams.

5. The lettuce seed capable of producing the lettuce plant of claim 1 , wherein said lettuce plant further comprises a plant height of at least 19 centimeters.

6. The lettuce seed capable of producing the lettuce plant of claim 1 , wherein said lettuce plant further comprises a head diameter of at least 14 centimeters.

7. The lettuce seed capable of producing the lettuce plant of claim 1 , wherein said leaf length to width ratio is between about 1.2 and about 2.1.

8. The lettuce seed capable of producing the lettuce plant of claim 1 , wherein said leaf length to width ratio is between about 1.2 and about 1.8.

9. The lettuce seed capable of producing the lettuce plant of claim 1 , wherein the adaxial leaf blade of an inner leaf from said lettuce plant further comprises a blanched color, ranging from about RHS 145C to about RHS 145D.

10. The lettuce seed capable of producing the lettuce plant of claim 1 , wherein the adaxial leaf blade of an outer leaf from said lettuce plant further comprises a color which ranges from about RHS 146A to about RHS 146B.

11. A lettuce seed capable of producing a lettuce plant, said lettuce plant comprising a head having an outer leaf comprising a leaf length to width ratio between about 1.2 and about 2.7 and taste, texture, and density of an iceberg lettuce type.

12. The lettuce seed capable of producing the lettuce plant of claim 11 , wherein said lettuce plant further comprises at least one morphological characteristic selected from the group consisting of an elliptical leaf stature, a spatulate leaf shape, and a semi open head formation.

13. The lettuce seed capable of producing the lettuce plant of claim 12 , wherein said lettuce plant comprises at least two of said morphological characteristics.

14. The lettuce seed capable of producing the lettuce plant of claim 11 , wherein said lettuce plant comprises a head weight of at least 900 grams.

15. The lettuce seed capable of producing the lettuce plant of claim 11 , wherein said lettuce plant further comprises a plant height of at least 19 centimeters.

16. The lettuce seed capable of producing the lettuce plant of claim 11 , wherein said lettuce plant further comprises a head diameter of at least 14 centimeters.

17. The lettuce seed capable of producing the lettuce plant of claim 11 , wherein said 1 leaf length to width ratio is between about 1.2 and about 2.1.

18. The lettuce seed capable of producing the lettuce plant of claim 11 , wherein said leaf length to width ratio is between about 1.2 and about 1.8.

19. The lettuce seed capable of producing the lettuce plant of claim 11 , wherein the adaxial leaf blade of an inner leaf from said lettuce plant further comprises a blanched color, ranging from about RHS 145C to about RHS 145D.

20. The lettuce seed capable of producing the lettuce plant of claim 11 , wherein the adaxial leaf blade of an outer leaf from said lettuce plant further comprises a color which ranges from about RHS 146A to about RHS 146B.

21. A lettuce seed capable of producing a lettuce plant, said lettuce plant comprising at least one morphological characteristic of a romaine lettuce type selected from the group consisting of an elliptical stature, a spatulate leaf shape, and a semi open head formation and at least one morphological characteristic of an iceberg lettuce type selected from the group consisting of crisp texture, bland taste, high water content, and firm density.

22. The lettuce seed capable of producing the lettuce plant of claim 21 , wherein said leaf further comprises at least two morphological characteristics of an iceberg lettuce type.

23. The lettuce seed capable of producing the lettuce plant of claim 22 , wherein said lettuce plant comprises at least three of said morphological characteristics of an iceberg lettuce type.

24. The lettuce seed capable of producing the lettuce plant of claim 21 , wherein said lettuce plant further comprises a head weight of at least 900 grams.

25. The lettuce seed capable of producing the lettuce plant of claim 21 , wherein said lettuce plant further comprises a plant height of at least 19 centimeters.

26. The lettuce seed capable of producing the lettuce plant of claim 21 , wherein said lettuce plant further comprises a head diameter of at least 14 centimeters.

27. The lettuce seed capable of producing the lettuce plant of claim 21 , wherein said leaf length to width ratio is between about 1.2 and about 2.7.

28. The lettuce seed capable of producing the lettuce plant of claim 21 , wherein said leaf length to width ratio is between about 1.2 and about 1.8.

29. The lettuce seed capable of producing the lettuce plant of claim 21 , wherein the adaxial leaf blade of an inner leaf from said lettuce plant further comprises a blanched color, ranging from about RHS 145C to about RHS 145D.

30. The lettuce seed capable of producing the lettuce plant of claim 21 , wherein the adaxial leaf blade of an outer leaf from said lettuce plant further comprises a color which ranges from about RHS 146A to about RHS 146B.
