Abstract
The present invention relates to a Lactuca sativa seed designated 79-110 RZ, which exhibits resistance to downy mildew (Bremia lactucae) races B1:1 to B1:28 and Ca-I to Ca-VIII, resistance to currant-lettuce aphid (Nasonovia ribisnigri), as well as an extraordinary high number of substantially equally sized dark green leaves. The present invention also relates to a Lactuca sativa plant produced by growing the 79-110 RZ seed. The invention further relates to methods for producing the lettuce cultivar, represented by lettuce variety 79-110 RZ.
Claims34
Lettuce plant exhibiting a combination of traits including resistance to downy mildew (Bremia lactucae) races B1:1 to B1:28 and Ca-I to Ca-VIII, resistance to currant-lettuce aphid (Nasonovia ribisnigri), as well as an extraordinary high number of substantially equally sized dark green leaves, representative seed of which having been deposited under NCIMB Accession No. 42132.
Lettuce plant designated 79-110 RZ, representative seed of which having been deposited under NCIMB Accession No. 42132.
A method of producing a lettuce cultivar containing a combination of traits including resistance to downy mildew (Bremia lactucae) races B1:1 to B1:28 and Ca-I to Ca-VIII, resistance to currant-lettuce aphid (Nasonovia ribisnigri), as well as an extraordinary high number of substantially equally sized dark green leaves, 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 (Bremia lactucae) races B1:1 to B1:28 and Ca-I to Ca-VIII, resistance to currant-lettuce aphid (Nasonovia ribisnigri), as well as an extraordinary high number of substantially equally sized dark green leaves, and, selfing said selected F2-plants to produce F3 progeny seed;
- selecting F3-plants for exhibiting resistance to downy mildew (Bremia lactucae) races B1:1 to B1:28 and Ca-I to Ca-VIII, resistance to currant-lettuce aphid (Nasonovia ribisnigri), as well as an extraordinary high number of substantially equally sized dark green leaves, optionally followed by more selfing and selection steps.
Lettuce plant having morphological and/or physiological characteristics of a lettuce plant, representative seed of which having been deposited under NCIMB Accession No. 42132.
A method of introducing a desired trait into a plant of lettuce variety 79-110 RZ comprising:
- (a) crossing a plant of lettuce variety 79-110 RZ, representative seed of which having been deposited under NCIMB Accession No. NCIMB 42132, 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 79-110 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 79-110 RZ, when grown in the same environmental conditions.
A method for producing a seed of a 79-110 RZ-derived lettuce plant comprising (a) crossing a plant of lettuce variety 79-110 RZ, representative seed of which having been deposited under NCIMB Accession No. NCIMB 42132, with a second lettuce plant, and (b) whereby seed of a 79-110 RZ-derived lettuce plant form.
