Genetic diversity, introduction, production, selectionAbstract
Romaine lettuce is a type of introduced vegetable gaining popularity in Indonesia. There are not many romaine lettuce varieties that are suitable to be grown in the lowlands to fulfil the demand. The study aimed to determine the growth and morphological characteristics of six romaine lettuce varieties grown in the lowland area. This study was conducted from February to April 2024 on a house rooftop in Bojongsari, Depok, West Java. The study used a randomized complete block design (RCBD) with treatment of various varieties of romaine lettuce consisting of six different varieties: Green Romaine, Red Romaine, Parris Island, Dacosta, Maximus, and Tiberius. The results showed that the Tiberius variety had the highest growth variables (crop height, number of leaves, leaf length, leaf width, gross weight, and consumption weight). All six varieties had the diversity of head shape, leaf color, leaf shape, leaf tip shape, and leaf attitude.References
