Screening of nonpathogenic disorder-resistant romaine lettuce cultivars for export and the introduction of labor-saving cultivation
Romaine lettuce is a vegetable that is eaten raw in salad and sandwiches in western countries, however it's both eaten raw and cooked in Taiwan. In the recent decade, the domestic trading quantity and export amount have increased year by year. At present, romaine lettuce has become a better option to expand market diversification for lettuce exportation in Taiwan. However, lacking an adequate cultivar and insufficient labor are still major obstacles for romaine lettuce production for exportation. In order to increase the product's quality and defect-free rate, the three varieties of romaine in previous trials will be evaluated for physiological disorder rates during storage, shelf life, edible rate and time of bolting. We also plan to establish a singular fertilization method for romaine in autumn and spring cultivation. By the end of 2019, we expect to develop a labor-saving cultivation of romaine with a longer shelf life.
