Abstract
The present invention relates to a Lactuca sativa seed designated 79-348 RZ, which exhibits resistance against downy mildew races B1:1 to B1:28 and CA-I, CA-IIA, CA-IIB, CAIII, CA-IV, CA-V, CA-VI, CA-VII, CA-VIII (Bremia lactucae), resistance to Nasonovia ribisnigri, resistance to LMV, and an extraordinary high number of oakleaf-shaped leaves of substantially equal size with a semi-erect adult leaf attitude. The present invention also relates to a Lactuca sativa plant produced by growing the 79-348 RZ seed. The invention further relates to methods for producing the lettuce cultivar, represented by lettuce variety 79-348 RZ.
Claims33
A lettuce plant exhibiting a combination of traits including resistance against downy mildew races B1:1 to B1:28 and CA-I, CA-IIA, CA-IIB, CA-III, CA-IV, CA-V, CA-VI, CA-VII, CA-VIII (Bremia lactuacae), resistance to Nasonovia ribisnigri, resistance to lettuce mosaic virus (LMV), and a leaf trait of 2 to 4 times more leaves of substantially equal size than a lettuce plant not having the leaf trait, wherein the leaves are oakleaf-shaped with a semi-erect adult leaf attitude, representative seed of which having been deposited under NCIMB Accession No. 42135.
A lettuce plant designated 79-348 RZ, representative seed of which having been deposited under NCIMB Accession No. 42135.
A method of producing a lettuce cultivar containing a combination of traits including resistance against downy mildew races B1:1 to B1:28 and CA-I, CA-IIA, CA-IIB, CA-III, CA-IV, CA-V, CA-VI, CA-VII, CA-VIII (Bremia lactuacae), resistance to Nasonovia ribisnigri, resistance to lettuce mosaic virus (LMV), and a leaf trait of 2 to 4 times more leaves of substantially equal size than a lettuce plant not having the leaf trait, wherein the leaves are oakleaf-shaped with a semi-erect adult leaf attitude, representative seed of which having been deposited under NCIMB Accession No. 42135, comprising:
- crossing a mother lettuce plant with a farther lettuce plant to produce a hybrid seed;
- growing said hybrid seed to produce a hybrid plant;
- selfing said hybrid seed to produce F2 progeny seed;
- selecting said F2-plants for exhibiting resistance against downy mildew races B1:1 to B1:28 and CA-I, CA-IIA, CA-IIB, CA-III, CA-IV, CA-V, CA-VI, CA-VII, CA-VIII (Bremia lactuacae), resistance to Nasonovia ribisnigri, resistance to lettuce mosaic virus (LMV), and a leaf trait of 2 to 4 times more leaves of substantially equal size than a lettuce plant not having the leaf trait, wherein the leaves are oakleaf-shaped with a semi-erect adult leaf attitude, and, selfing said selected F2-plants to produce F3 progeny seed;
- selecting F3-plants for exhibiting resistance against downy mildew races B1:1 to B1:28 and CA-I, CA-IIA, CA-IIB, CA-III, CA-IV, CA-V, CA-VI, CA-VII, CA-VIII (Bremia lactuacae), resistance to Nasonovia ribisnigri, resistance to lettuce mosaic virus (LMV), and a leaf trait of 2 to 4 times more leaves of substantially equal size than a lettuce plant not having the leaf trait, wherein the leaves are oakleaf-shaped with a semi-erect adult leaf attitude, representative seed of which having been deposited under NCIMB Accession No. 42135, optionally followed by more selfing and selection steps.
A method of introducing a desired trait into a plant of lettuce variety 79-348 RZ comprising:
- (a) crossing a plant of lettuce variety 79-348 RZ, representative seed of which having been deposited under NCIMB Accession No. 42135, with a second lettuce plant that comprises the desired trait to produce F1 progeny;
- (b) selecting an F1 progeny that comprises the desired trait;
- (c) crossing the selected F1 progeny with a plant of lettuce variety 79-348 RZ, to produce backcross progeny and (d) selecting backcross progeny comprising the desired trait and the physiological and morphological characteristics of a plant of lettuce variety 79-348 RZ, when grown in the same environmental conditions.
A method for producing a seed of a 79-348 RZ-derived lettuce plant comprising
- (a) crossing a plant of lettuce variety 79-348 RZ, representative seed of which having been deposited under NCIMB Accession No. 42135, with a second lettuce plant, and (b) whereby seed of a 79-348 RZ-derived lettuce plant form.
A lettuce plant exhibiting a combination of traits including resistance against downy mildew races B1:1 to B1:28 and CA-I, CA-IIA, CA-IIB, CA-III, CA-IV, CA-V, CA-VI, CA-VII, CA-VIII (Bremia lactuacae), resistance to Nasonovia ribisnigri, resistance to lettuce mosaic virus (LMV), and a leaf trait of 2 to 4 times more leaves of substantially equal size than a lettuce plant not having the leaf trait, wherein the leaves are oakleaf-shaped with a semi-erect adult leaf attitude, and having genetic information for so exhibiting the combination of traits, wherein the genetic information is as contained in the plant, representative seed of which having been deposited under NCIMB Accession No. 42135.
