Abstract: The present invention relates to a Lactuca sativa seed designated 79-82 RZ, which exhibits resistance against downy mildew (Bremia lactucae) strains BL:1- (Bremia lactucae), currant-lettuce aphid (Nasonovia ribisnigri) and lettuce mosaic virus (LMV) as well as blond, thin, deeply-incised, nicely-frilled leaves. The present invention also relates to a Lactuca sativa plant produced by growing the 79-82 RZ seed. The invention further relates to methods for producing the lettuce cultivar, represented by lettuce variety 79-82 RZ.

Abstract: The present invention relates to a Lactuca sativa seed designated 79-163 RZ, which exhibits resistance to downy mildew (Bremia lactucae Regel.) races B1:1 to B1:28, and which has an extraordinary high number of red-colored, oakleaf-shaped leaves of substantially equal size. The present invention also relates to a Lactuca sativa plant produced by growing the 79-163 RZ seed. The invention further relates to methods for producing the lettuce cultivar, represented by lettuce variety 79-163 RZ.

Abstract: The present invention relates to a Lactuca sativa seed designated 79-41 RZ, which may exhibit resistance to downy mildew (Bremia lactucae Regel.), currant-lettuce aphid (Nasonovia ribis-nigri) and Lettuce Mosaic Virus (LMV), and which may have light green, moderately glossy, deeply-incised, strongly undulated leaves. The present invention also relates to a Lactuca sativa plant produced by growing the 79-41 seed. The invention further relates to methods for producing the lettuce cultivar, represented by lettuce variety 79-41 RZ.

Abstract: The present invention relates to a head-forming lettuce plant of the species Lactuca sativa having red leaves throughout the head, including the heart. The red leaves in the heart are red even in the absence of radiation with wavelengths shorter than 400 nm, wherein the absence of radiation with wavelengths shorter than 400 nm is in the growing environment during the complete period from sowing until observation. The ratio between anthocyanin and chlorophyll is between 4 and 50, preferably between 9 and 27. The invention also relates to progeny of the plant.
