Fruit qualities of Lonicera caerulea advanced selections.

Utilizing Russian, Japanese and Kurile germplasm in breeding beginning in 2001 has resulted in a diversity of fruit characteristics. The breeding strategy involved controlled crosses to combine the three types of germplasm. In the last 3 years, 248 advanced selections were evaluated from over 15,000 seedlings in the current generation. This population of seedlings was created from 127 parents crossed in 459 combinations over 4 years. Fruit weights averaged from 1.2 to 3.6 grams. Sugar content averaged from 10.5 to 23.5o brix. Total acidity averaged from 1.0 to 3.8 % meq malic acid. Anthocyanin content was more variable than flavonoid content which was more variable than phenolic content. Anthocyanins were correlated with flavonoids and phenolics with R2 values of 0.740 and 0.764 respectively. The correlation of flavonoids and phenolics had an R2 value of 0.907. Anthocyanin testing is recommended as an initial screen for nutraceutical value due to the low cost, ease and speed of the tests. A wide range of fruit shapes was observed in the seedling population but advanced selections were mostly stretched ovals.
