Cotton variety st 6448glb2

Abstract

The cotton variety ST 6448GLB2 is disclosed. The invention relates to seeds, plants, plant cells, plant tissue, harvested products and cotton lint as well as to hybrid cotton plants and seeds obtained by repeatedly crossing plants of variety ST 6448GLB2 with other plants. The invention also relates to plants and varieties produced by the method of essential derivation from plants of ST 6448GLB2 and to plants of ST 6448GLB2 reproduced by vegetative methods, including but not limited to tissue culture of regenerable cells or tissue from ST 6448GLB2.

1 . A seed of cotton variety ST 6448GLB2, wherein a representative seed of said variety was deposited under ATCC Accession No. XXXXX. 
     
     
         2 . A plant, or a part thereof, produced by growing the seed of  claim 1 . 
     
     
         3 . A plant, or a part thereof, obtained by vegetative reproduction from the plant, or a part thereof, of  claim 2 , said plant, or a part thereof, expressing all the phenotypic characteristics of cotton variety ST 6448GLB2, a sample of seed having been deposited under ATCC Accession No. XXXXX. 
     
     
         4 . A process of vegetative reproduction of cotton variety ST 6448GLB2 comprising, culturing regenerable cells or tissue from ST 6448GLB2, a sample of seed having been deposited under ATCC Accession No. XXXXX. 
     
     
         5 . A cell or tissue culture produced from the plant, or a part thereof, of  claim 2 . 
     
     
         6 . A cotton plant regenerated from the cell or tissue culture of  claim 5 , said plant expressing all the phenotypic characteristics of ST 6448GLB2, a sample of seed having been deposited under ATCC Accession No. XXXXX. 
     
     
         7 . A method of producing a F1 hybrid cotton seed, comprising the steps of crossing the plant of  claim 2  with a different cotton plant and harvesting the resultant F1 hybrid cotton seed. 
     
     
         8 . A F1 hybrid cotton seed produced by the method of  claim 7 . 
     
     
         9 . A F1 hybrid cotton plant, or part thereof, produced by growing the hybrid seed of  claim 8 . 
     
     
         10 . A plant obtained by the vegetative reproduction of the cotton plant of  claim 9 . 
     
     
         11 . A method of producing a cotton seed comprising the steps of crossing the plant of  claim 10  with a different cotton plant and harvesting the resultant cotton seed. 
     
     
         12 . A method of introducing a desired trait into a cotton plant, the method comprising, transforming the plant of  claim 2  with a transgene that confers the desired trait, wherein the transformed plant retains all the phenotypic characteristics of cotton variety ST 6448GLB2 and contains the desired trait. 
     
     
         13 . The method of  claim 12 , wherein said desired trait is fiber quality, herbicide resistance, insect resistance, bacterial disease resistance or fungal disease resistance. 
     
     
         14 . A method of introducing a desired trait into a cotton plant, the method comprising transforming the plant of  claim 9  with a transgene that confers the desired trait, wherein the transformed plant retains all the phenotypic characteristics of cotton variety ST 6448GLB2 and contains the desired trait, seed of said variety having been deposited as ATCC Accession No. XXXXXYY. 
     
     
         15 . A cotton plant produced by the method of  claim 12 . 
     
     
         16 . A method of introducing a single locus conversion into cotton variety ST 6448GLB2 comprising:
 (a) crossing a plant of variety ST 6448GLB2 with a second plant comprising a desired single locus to produce F1 progeny plants;   (b) selecting F1 progeny plants that have the single locus to produce selected F1 progeny plants;   (c) crossing the selected progeny plants with at least a first plant of variety ST 6448GLB2 to produce backcross progeny plants;   (d) selecting backcross progeny plants that have the single locus and all physiological and morphological characteristics of cotton variety ST 6448GLB2 to produce selected backcross progeny plants; and   (e) repeating steps (c) and (d) one or more times in succession to produce selected second or higher backcross progeny plants that comprise the single locus and otherwise comprise all of the physiological and morphological characteristics of cotton variety ST 6448GLB2 when grown in the same environmental conditions.   
     
     
         17 . The method of  claim 16 , wherein the single locus confers a trait selected from the group consisting of male sterility; herbicide tolerance; insect or pest resistance; disease resistance; modified fatty acid metabolism; modified carbohydrate metabolism; and modified cotton fiber characteristics.
