| Abstract: | Cacao is an important tropical economic crop, however, the current main varieties are limited in China. The critical task is to identify the excellent cacao strains and cultivate new cacao varieties. The comparison experiment was performed to investigate the different performance of botanical, agronomic and quality traits among the six cacao strains/varieties (XYS-1, XYS-2, XYS-3, XYS-4, XYS-5, ‘Reyin No.4’ in Wanning, Hainan. XYS-5 had the longest fruit ripening period, up to 192 days, while the shortest fruit ripening period was XYS-1, only 162 days. The average fruit length for XYS-4 was 218.27 mm, and significantly higher than other five strains/varieties. XYS-2 showed highest yield, with dry seed weight per fruit of 46.48 g and fruit number per plant of 59. There were no big differences between XYS-2 and ‘Reyin No.4’, but there were significant differences between XYS-2 and others. Cocoa butter content for XYS-5 was 51.27%, significantly higher than that of ‘Reyin No.4’ variety, while XYS-1 had the lowest cocoa butter content with 43.67%. Among the six strains/varieties, XYS-2 and XYS-4 which showed better performance in plant growth potential, yield and quality, and suitable to popularize and cultivate in Hainan island. |
