HIGH TEMPERATURE GERMINATING LETTUCE SEEDS

摘要

The present invention relates to lettuce plants (Lactuca sativa L.) which may comprise a genetic determinant, which when homozygously present in a seed, provides the seed in an unprimed state with the capability to germinate at a high temperature, which genetic determinant is obtainable from a lettuce plant which may comprise said genetic determinant, representative seed which was deposited with the NCIMB under accession number NCIMB 41914, NCIMB 41915, NCIMB 41916, NCIMB 41917, NCIMB 41918, NCIMB 41919, NCIMB 41922, NCIMB 41923, and NCIMB 41926.

主权项

1. A seed lot of the species Lactuca sativa L. wherein the seeds belonging to the seed lot comprise a genetic determinant, which when homozygously present, provides the seeds in an unprimed state with the capability to germinate at a high temperature, and which seed lot is characterized in that the GT50 Dark of said seed lot is at least 6.2° C. higher than the GT50 Dark of a seed lot of seeds not comprising the genetic determinant, and wherein said genetic determinant is as present in seeds of which a representative sample has been deposited under accession number NCIMB 41914, NCIMB 41915, NCIMB 41916, NCIMB 41917, NCIMB 41918, NCIMB 41919, NCIMB 41922, NCIMB 41923, and NCIMB 41926.
