Abstract
The present invention relates to a Lactuca sativa seed designated 79-25 RZ, which exhibits resistance to downy mildew races Bl:1 to Bl:28 and CA-I, CA-IIA, CA-IIB, CA-III to CA-VIII (Bremia lactucae Regel), as well as deeply red, crisp, deeply-incised, nicely-filled leaves, and a small plant size. The present invention also relates to a Lactuca sativa plant produced by growing the 79-25 RZ seed. The invention further relates to methods for producing the lettuce cultivar, represented by lettuce variety 79-25 RZ.
Claims33
A lettuce plant exhibiting a combination of traits including resistance to downy mildew races Bl:1 to Bl:28 and CA-I, CAIIA, CA-IIB, CA-III to CA-VIII (Bremia lactucae Regel), as well as deeply red, crisp, deeply-incised, nicely-frilled leaves, and a small plant size, representative seed of which having been deposited under NCIMB Accession No. 41873.
A lettuce plant designated 79-25 RZ, representative seed of which having been deposited under NCIMB Accession No. 41873.
A method of producing a lettuce cultivar containing a combination of traits including resistance to downy mildew races Bl:1 to Bl:28 and CA-I, CA-IIA, CA-IIB, CA-III to CA-VIII (Bremia lactucae Regel), as well as deeply red, crisp, deeply-incised, nicely-filled leaves, and a small plant size, representative seed of which having been deposited under NCIMB Accession No. 41873, comprising:
- crossing a mother lettuce plant with a father 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 to downy mildew races Bl:1 to Bl:28 and CA-I, CA-IIA, CA-IIB, CA-III to CA-VIII (Bremia lactucae Regel), as well as deeply red, crisp, deeply-incised, nicely-filled leaves, and a small plant size, and, selfing said selected F2-plants to produce F3 progeny seed;
- selecting F3-plants for exhibiting resistance to downy mildew races Bl:1 to Bl:28 and CA-I, CA-IIA, CA-IIB, CA-III to CA-VIII (Bremia lactucae Regel), as well as deeply red, crisp, deeply-incised, nicely-filled leaves, and a small plant size, representative seed of which having been deposited under NCIMB Accession No. 41873, optionally followed by more selfing and selection steps.
A lettuce plant containing genetic information for exhibiting a combination of traits including resistance to downy mildew races Bl:1 to Bl:28 and CA-I, CAIIA, CA-IIB, CA-III to CA-VIII (Bremia lactucae Regel), as well as deeply red, crisp, deeply-incised, nicely-frilled leaves, and a small plant size, wherein said genetic information is as found in a plant, representative seed of which having been deposited under NCIMB Accession No. 41873.
A method of introducing a desired trait into a plant of lettuce variety 79-25 RZ comprising:
- (a) crossing a plant of lettuce variety 79-25 RZ, representative seed of which having been deposited under NCIMB Accession No. NCIMB 41873, 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 79-25 RZ, to produce backcross progeny and (d) selecting backcross progeny comprising the desired trait and physiological and morphological characteristics of a plant of lettuce variety 79-25 RZ, when grown in the same environmental conditions.
A method for producing a seed of a 79-25 RZ-derived lettuce plant comprising (a) crossing a plant of lettuce variety 79-25 RZ, representative seed of which having been deposited under NCIMB Accession No. NCIMB 41873, with a second lettuce plant, and (b) whereby seed of a 79-25 RZ-derived lettuce plant form.
A lettuce plant exhibiting a combination of traits including resistance to downy mildew races Bl:1 to Bl:28 and CA-I, CAIIA, CA-IIB, CA-III to CA-VIII (Bremia lactucae Regel), as well as deeply red, crisp, deeply-incised, nicely-frilled leaves, and a small plant size, and has genetic information for so exhibiting the combination of traits, wherein the genetic information is as contained in a plant, representative seed of which having been deposited under NCIMB Accession No. 41873.
