Abstract

Certain aspects of the present disclosure relate to upright heading iceberg lettuce plants including a space between the base of the head and the top of the ground, wherein the space includes an increased length of core outside of the processing material of the head (i.e., external stem). The increased external stem lengths of the upright heading iceberg lettuce plants of the present disclosure make them suitable for machine harvesting. Other aspects of the present disclosure relate to methods of generating and selecting upright heading iceberg lettuce plants. New upright heading iceberg lettuce varieties designated ‘E01E.70111’ Lot A, ‘E01E.70111’ Lot B, ‘E01E.70168’ Lot A, and ‘E01E.70168’ Lot B are described.
