By DEU146: Field experiment in Gatersleben. Sown into pots in the greenhouse on 10/3/2009 and later transferred to trays. Planted: 15/5/2009. Row length 200cm and row distance 40 cm. Per accession 5 + 6 plants were planted in 2 rows. Harvest maturity mostly reached in June. Some damage by wireworms. Soil: Tschernosem (black earth, weak sandy clay). No irrigation.	ECPGR CCDB Lettuce data from AUT046, DEU146, GBR006, GBR017, NLD037 and SVN019 extracted 2018-12-03.

By GBR006. Seeds were sown in seed compost (26/2) and pricked out into medium grade horticultural compost in 7cm pots (15/3). Plants were transplanted into a Dutchlight frame (29/4) containing sandy loam enhanced using horticultural compost. The planting design was 5 rows of 3 plants with 40cm between rows and plants 30cm apart.	ECPGR CCDB Lettuce data from AUT046, DEU146, GBR006, GBR017, NLD037 and SVN019 extracted 2018-12-03.
