A field study was conducted in the Constanza Valley [1234 m (4048.6 ft) above sea level, loam soil, average temperature 14.7 to 25.0 °C (58.46 to 77.00 °F), photoperiod 11.2 to 12.6 hours] in the Dominican Republic, to compare the head characteristics, damage caused by diamondback moth larvae (Plutella xylostella), yield, and earliness of cabbage (Brassica oleracea Group Capitata) hybrids 'Bravo', 'Blue Vantage', 'Express', 'Genesis', 'Green Cup', 'Head Start', SW 2007, 'Hildur' (SW 2008), 'Gretania' (SW 2010), 'Hampus' (SW 2011), and XPH 847, to the industry standard 'Izalco'. 'Genesis' had the highest yield among all the hybrids tested, including 'Izalco'. The yield of 'Izalco' did not significantly differ from the yield of 'Blue Vantage', 'Green Cup', 'Express', XPH 847, SW 2007, and 'Bravo'. However, 'Bravo' and 'Express' were more damaged by diamondback moth larvae. 'Head Start', XPH 847, SW 2007, 'Gretania', 'Hildur', and 'Hampus' were either significantly less productive or more susceptible to damage by the diamondback moth larvae than 'Izalco'. In terms of yield, earliness, head shape, and losses due to the diamondback moth larvae, 'Green Cup', 'Blue Vantage' and 'Genesis' were comparable or superior to 'Izalco'. [ABSTRACT FROM AUTHOR]
