Abstract
The present invention relates to a lettuce variety NUN 9044 LT (referred to as “REDGLACE”) having resistance against at least strains Bl: 1 to Bl: 26 of downy mildew (Bremia lactucae) and mature leaves which exhibit red color throughout their apical part. The invention further relates to methods for producing the new lettuce variety and representative seed having been deposited under Accession No. NCIMB 42228.
Claims22
A lettuce plant designated NUN 9044 LT, referred to as REDGLACE, a representative sample of seeds of which having been deposited under Accession Number NCIMB 42228.
A seed designated NUN 9044 LT, a representative sample of seeds having been deposited under Accession Number NCIMB 42228.
A progeny plant of lettuce variety designated NUN 9044 LT obtained by further breeding with said variety, wherein said progeny plant has at least the essential physiological and/or morphological characteristic of the variety designated NUN 9044 LT, a representative sample of seeds of which having been deposited under Accession Number NCIMB 42228 wherein said progeny further has black (grey-brown) seed color.
An Essentially Derived Variety of NUN 9044 LT having at least one, two or three physiological and/or morphological characteristics which are different from those of NUN 9044 LT and which otherwise has essentially all physiological and/or morphological characteristics of a lettuce plant designated NUN 9044 LT, a representative sample of seeds of which having been deposited under Accession Number NCIMB 42228.
A method of introducing a single locus conversion into a lettuce plant designated NUN 9044 LT comprising
- (a) crossing a plant of variety designated NUN 9044 LT with a second lettuce plant comprising a desired single locus to produce at least one F1 progeny plant;
- (b) selecting F1 progeny plant that has said desired single locus;
- (c) crossing the selected progeny plant NUN 9044 LT to produce backcross progeny plants;
- (d) selecting backcross progeny plant that has said desired single locus and at least the essential physiological and/or morphological characteristic of a plant designated NUN 9044 LT to produce at least one selected backcross progeny plant;
- and
- (e) repeating steps (c) and (d) one or more times in succession to produce at least one selected second or higher backcross progeny plant that comprises the single locus and otherwise comprises essentially all physiological and/or morphological characteristics of a plant designated NUN 9044 LT,
- wherein a representative sample of seeds of which having been deposited under Accession Number NCIMB 42228.
