One-hundred and five cultivars representing s species of Capsicum were screened at constant 13, 16, 18°C and greenhouse temperatures. Daily observation on emergence were made for 60 days following seeding in flats.Using a calculated emergence index as the criterion for emergence at low temperatures, the various cultivars were classified by species. Within the C. annum group significant differences were found between cultivars for the lowest and highest index suggesting heritability of this trait. The fowest indexes for all temperatures was a cultivar from the C. baccatum v. pendulum group.
