Anthocyanin profiles in fruit from seminal primocane and floricane-fruiting Rubus cultivars
Berries from a group of seminal of floricane/primocane-fruiting blackberry and raspberry cultivars were analyzed for anthocyanin content and profile using high performance liquid chromatography.
Cyanidin-based anthocyanins were dominant in both blackberry cultivars Chester Thornless and Prime-Ark® 45 and raspberry cultivars Latham and Heritage. Primocane fruit from Prime-Ark® 45 or Heritage had about 35 and 15% less total anthocyanin than floricane fruit (67 vs. 104 and 100 vs. 115 mg 100 g‑1 fresh weight (FW), respectively). Floricane fruit had higher and lower proportions of cyanidin 3-glucoside (C3G) and cyanidin 3-rutinoside (C3R), respectively, than primocane fruit in Prime-Ark® 45. In contrast, the %C3G and cyanidin 3-sophoroside (C3So) were similar between floricane and primocane fruit of Heritage. Between cultivars, Chester Thornless floricane fruit had twice as much total anthocyanin as Prime-Ark® 45 floricane fruit (234 vs. 104 mg 100 g‑1 FW, respectively). The percentage of C3G, the dominant pigment, was similar between blackberry cultivars. Chester Thornless had less C3R but more cyanidin-3-malonylglucoside and cyanidin-3-dioxalylglucoside than Prime-Ark® 45. Compared to Latham, Heritage floricane raspberries had 30% more total anthocyanin than Latham (115 vs. 76 mg 100 g‑1 FW) and C3So.
In contrast, 27% of the total anthocyanin in Latham was cyanidin 3-glucosylrutinoside, compared to 4% in Heritage. Latham had less C3G and more C3R than Heritage. Cyanidin 3-sambubioside was detected in Latham but not in Heritage. Results indicate that anthocyanin profiles are conserved within primocane and floricane fruit in raspberry and blackberry.
Differences in total anthocyanin content and relative profiles of floricane fruit were found across cultivars, especially in raspberry.
Profiles between raspberry cultivars were quite different compared to the profiles of the two blackberry cultivars.
The marked difference in anthocyanin profiles between blackberries and raspberries may help with inheritance studies in Rubus.
