Cultivar 1941: Jri9-6

Jri9-6 appears in the University of Saskatchewan haskap program as selection JR19-6. It was an advanced haskap selection of Lonicera caerulea. In 2010, it was evaluated against Borealis and other breeding selections. The report calls JR19-6 very promising. It had one of the largest bushes in Block 6 and was among the most productive plants there. [S1]

JR19-6 was also used as a female parent for open-pollinated seed collected in 2010. The seed came from advanced selections and was kept for possible experiments, grower distribution, or new plantings. [S1]

JR19-6 had large fruit in the trial. Table 23 lists berry dimensions of 24.8 mm long, 15.4 mm wide, and 12.2 mm deep, with a berry weight of 2.5 g. The report also says JR19-6 had the heaviest berry weight among the selections discussed on the previous narrative page. [S1]

Fruit quality was favorable. On a 1 to 5 scale, where 5 was best and a bitterness score of 5 meant no bitterness, JR19-6 scored 3 for texture, 3.5 for bloom, 4.5 for sweetness, 3 for sourness, 5 for bitterness, 4 for aroma, and 3.8 overall. Its soluble solids were 14.7 brix, with pH 3.38 and total acidity of 1.58% citric acid. The report says JR19-6 had one of the best sensory evaluations. Its sugar content was only average, but still higher than Borealis. [S1]

Winter survival was the main weakness. When pollen was collected in spring 2011, JR19-6 had winter killed very badly. The report says wet conditions may have contributed. Because few plants in the field showed winter damage in 2011, JR19-6 was not considered worth releasing as a new variety. It was used further in breeding instead. [S1]

The available source does not give direct parentage. It places JR19-6 in the University of Saskatchewan haskap breeding program and in advanced selection work involving Russian, Japanese, and Kurile germplasm. The packet does not establish its exact cross or species ancestry beyond haskap, Lonicera caerulea. [S1]
