Abstract
The present invention relates to a Lactuca sativa seed designated 41-132 RZ, which may exhibit a combination of traits including resistance against downy mildew (Bremia lactucae Regel) races B1:1 to B1:28, CA-I, CA-IIA, CA-IIB, CA-III, CA-IV, CA-V, CA-VI, CA-VII, CA-VIII, and strains E138, and BGAU1, currant lettuce aphid (Nasonovia ribisnigri) biotype Nr:0, corky root rot (Sphingomonas suberifaciens), as well as broad base leaves, and slow bolting. The present invention also relates to a Lactuca sativa plant produced by growing the 41-132 RZ seed. The invention further relates to methods for producing the lettuce cultivar, represented by lettuce variety 41-132 RZ.
Claims33
A lettuce plant designated 41-132 RZ, representative seed of which having been deposited under NCIMB Accession No. NCIMB 42155, wherein said plant comprises at least the following combination of traits including resistance against downy mildew (Bremia lactucae Regel) races B1:1 to B1:28, CA-I, CA-IIA, CA-IIB, CA-III, CA-IV, CA-V, CA-VI, CA-VII, CA-VIII, and strains E138, and BGAU1, currant lettuce aphid (Nasonovia ribisnigri) biotype Nr:0, corky root rot (Sphingomonas suberifaciens), as well as broad base leaves, and slow bolting.
A method of producing a lettuce cultivar containing a combination of traits including resistance against downy mildew (Bremia lactucae Regel) races B1:1 to B1:28, CA-I, CA-IIA, CA-IIB, CA-III, CA-IV, CA-V, CA-VI, CA-VII, CA-VIII, and strains E138, and BGAU1, currant lettuce aphid (Nasonovia ribisnigri) biotype Nr:0, corky root rot (Sphingomonas suberifaciens), as well as broad base leaves, and slow bolting, 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 plant to produce F2 progeny seed;
- growing said F2 progeny seed to produce F2-plants;
- selecting said F2-plants for exhibiting resistance against downy mildew (Bremia lactucae Regel) races B1:1 to B1:28, CA-I, CA-IIA, CA-IIB, CA-III, CA-IV, CA-V, CA-VI, CA-VII, CA-VIII, and strains E138, and BGAU1, currant lettuce aphid (Nasonovia ribisnigri) biotype Nr:0, corky root rot (Sphingomonas suberifaciens), as well as broad base leaves, and slow bolting, and, selfing said selected F2-plants to produce F3 progeny seed;
- growing said F3 progeny seed to produce F3-plants;
- selecting F3-plants for exhibiting resistance against downy mildew (Bremia lactucae Regel) races B1:1 to B1:28, CA-I, CA-IIA, CA-IIB, CA-III, CA-IV, CA-V, CA-VI, CA-VII, CA-VIII, and strains E138, and BGAU1, currant lettuce aphid (Nasonovia ribisnigri) biotype Nr:0, corky root rot (Sphingomonas suberifaciens), as well as broad base leaves, and slow bolting, optionally followed by more selfing and selection steps.
A lettuce plant having morphological and/or physiological characteristics of a lettuce plant, representative seed of which having been deposited under NCIMB Accession No. NCIMB 42155.
A method of introducing a desired trait into a plant of lettuce variety 41-132 RZ comprising:
- (a) crossing a plant of lettuce variety 41-132 RZ, representative seed of which having been deposited under NCIMB Accession No. NCIMB 42155, 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 41-132 RZ, to produce backcross progeny and (d) selecting backcross progeny comprising the desired trait and the physiological and morphological characteristic of a plant of lettuce variety 41-132 RZ, when grown in the same environmental conditions.
A method for producing a seed of a 41-132 RZ-derived lettuce plant comprising (a) crossing a plant of lettuce variety 41-132 RZ, representative seed of which having been deposited under NCIMB Accession No. NCIMB 42155, with a second lettuce plant, and (b) whereby seed of a 41-132 RZ-derived lettuce plant form.
