Observation of flowering in different LcFT1 promoter types of litchi cultivars in 2017. ‘Guiwei’, ‘Nuomici’ and ‘Maguili’, three homozygous difficult-flowering type of LcFT1 promoter litchi cultivars (D, E, F), could not be flowering owing to the lack of low-temperature in winter of 2016, whereas ‘Sanyuehong’, ‘Feizixiao’ and ‘Lanzhu’ (three homozygous easy-flowering type of LcFT1 promoter litchi cultivars (A, B, C)) and ‘Ruanzhizaohong’, ‘Dahongpao’ and ‘Jinzhong’ (three heterozygous LcFT1 promoter litchi cultivars, G, H, I) could be flowering well. (A ‘Sanyuehong’, B ‘Feizixiao’, C ‘Lanzhu’, D ‘Guiwei’, E ‘Nuomici’, F ‘Maguili’, G ‘Ruanzhizaohong’, H ‘Dahongpao’, and I ‘Jinzhong’)
