Abstract
Provided relates to a crop Lisianthus (Eustoma grandiflorum) plants that do not require cold treatment (vernalization) for the inductions of bolting and flowering, and to means and methods for producing same.
Claims21
-33. (canceled)
An ornamental Eustoma grandiflorum (E. grandiflorum) crop plant comprising a genetic element comprising QTL derived from linkage group 2 of Eustoma exaltatum or a part thereof, wherein the QTL or part thereof confers vernalization independence to the ornamental E. grandiflorum crop plant.
The ornamental E. grandiflorum crop plant of claim 33, said plant bolts without receiving a cold treatment that is required for bolting in an ornamental E. grandiflorum crop plant devoid of said QTL or part thereof.
The ornamental E. grandiflorum crop plant of claim 33, wherein the QTL or part thereof conferring the vernalization independence is associated with at least one marker located on E. exaltatum linkage group 2 between about 25 cM and about 45 cM.
The ornamental E. grandiflorum crop plant of claim 33, wherein the genetic element is incorporated within linkage group 2 of said ornamental E. grandiflorum crop plant.
The ornamental E. grandiflorum crop plant of claim 33, wherein the QTL or part thereof further confers an increase in the number of flower stems during a second flowering flush compared to the stem number during the second flowering flush in a corresponding ornamental E. grandiflorum crop plant lacking the introduced QTL or parts thereof.
The ornamental E. grandiflorum crop plant of claim 33, said plant is devoid of deleterious genetic drags originated from the E. exaltatum linkage group 2.
A seed of the ornamental E. grandiflorum crop plant of claim 33, wherein a plant grown from the seed comprises a genetic element comprising QTL derived from linkage group 2 of Eustoma exaltatum or a part thereof, wherein the QTL or part thereof confers vernalization independence to the plant.
A cell or a tissue culture obtained from the plant of claim 33, wherein a plant developed from the cell or tissue culture comprises a genetic element comprising QTL derived from linkage group 2 of Eustoma exaltatum or a part thereof, wherein the QTL or part thereof confers vernalization independence to the plant.
An isolated polynucleotide comprising a nucleic acid sequence conferring vernalization independence, wherein the nucleic acid sequence is derived from a segment of E. exaltatum linkage group 2 located at from about 25 cM and 45 cM on linkage group 2, or a part thereof.
A method for producing an ornamental E. grandiflorum crop plant independent on vernalization requirement for bolting, the method comprises introducing into an ornamental E. grandiflorum crop plant a genetic element comprising QTL derived from linkage group 2 of Eustoma exaltatum or a part thereof, wherein the QTL or part thereof confers vernalization independence to the ornamental E. grandiflorum crop plant, thereby producing ornamental E. grandiflorum crop plant independent on vernalization requirement for bolting and/or flowering.
