Wiki Draft

Indigo Gem is a University of Saskatchewan haskap cultivar in the Indigo series. It belongs to the Lonicera caerulea breeding work described in the program's 2012 final report. It was tested as 9-15 before naming. It was one of the Row 9 selections named in winter 2011 after propagators and growers asked for names for numbered plants. The Indigo name was chosen because indigo is a color linked with haskap. "Blue" was avoided because it was already common in Russian introductions sold by Northwoods Nursery in Oregon. [S1]

The packet gives no direct parentage for Indigo Gem. It places the cultivar within the University of Saskatchewan Row 9 and Indigo series material. It is discussed closely with Indigo Treat and Indigo Yum, and in program context with Borealis and Tundra. The Indigo plants were released experimentally in case Borealis and Tundra were hard to propagate or developed field problems. [S1]

Indigo Gem had the smallest berries among the Row 9 selections discussed. The report says Indigo series fruit could be hard to identify by appearance alone. The fruit had slight chewiness, which the source suggests may indicate better durability. In sorting line tests, Tundra still ranked best for durability. [S1]

The original Indigo Gem bush was the most productive Row 9 plant. Some growers said it grew more upright and faster than related selections. It was also the only variety in that Indigo comparison reported as susceptible to leaf mildew. The others were classified as highly resistant. [S1]

For commercial production, Indigo Gem is discussed as a possible main variety for mechanical harvesting. Tundra and possibly Indigo Gem are described as more durable in machinery. The report also records Indigo Gem as one of the University of Saskatchewan named varieties used in 2010 crosses with Japanese germplasm selections and with Elwood. These are later breeding uses, not stated parentage. [S1]

No direct hardiness zone is given for Indigo Gem in the supplied evidence. Its documented context is the University of Saskatchewan haskap breeding program in Saskatchewan. The packet does not provide a cultivar specific winter survival or zone statement. [S1]
