Wiki Draft

Sungold is an apricot cultivar, listed as Prunus armeniaca L. It was released in 1961 by the Minnesota Agricultural Experiment Station Fruit Breeding Farm and is grouped with the relatively winter-hardy apricots Moongold and Sungold in the University of Minnesota source, citing Brooks and Olmo, 1997 [S1].

The same source records several experimental observations for Sungold seed and seedlings. In one field comparison, non-scarified seed germination reached 66.7%; in Experiment II, average field germination was 54.2% after 26 months of storage and 64.6% after 13 months [S1]. Greenhouse Experiment II reported 66.7% non-scarified germination and 83.3% scarified germination [S1].

Other recorded measurements include high pollen stainability, mostly 95% to 98% across storage intervals, and Experiment III survival of 86% in greenhouse conditions and 94% in the field [S1]. The supplied source also lists the collection or source code as HRC, but the packet does not expand that abbreviation [S1].
