Origin & Breeding History: 'SV1893GH' (experimental designations 'NAVC6V1200' and '12-NAV-1200') is a dry, edible bean in the navy bean market class, developed by pedigree breeding selection. It originated from a hand pollinated cross conducted in the spring of 2003 between the variety 'Regent' and the breeding line 'RWR2381'. The breeding work was conducted under the direction of Kenneth Kmiecik at the Seminis Vegetable Seed, Inc. breeding stations located in Filer, Idaho, and De Forest, Wisconsin, USA. From 2004 to 2006, plant type and visual yield were used as selection criteria for selection from the generations F2 to F6. Additionally in 2004, selection for resistance to Aphanomyces was conducted on the F3 generation. From 2007 to 2009, plant type and yield were used as selection criteria for selecting from the F6 generation. Additionally in 2009, selection for resistance to Bean Common Mosaic Virus (BCMV) and rust was conducted on the F6 generation. During the summer of 2010, a foundation seed crop was planted in an open field in Filer, Idaho, to assess yield. 200 single plants were harvested, bulked and subjected to yield trials in Filer, Idaho; De Forest, Wisconsin; Grand Marsh, Wisconsin; and Red River Valley, North Dakota and Manitoba. During the summer of 2011, foundation seed was planted as progeny rows in an open field in Filer, Idaho, and inspected for off-types and uniformity. Any suspect rows were removed. Seed from these progeny rows was then bulked and given the commercial name 'SV1893GH'.

Tests & Trials: The comparative trials for 'SV1893GH' were conducted during 2016 and 2017 at the University of Guelph, Ridgetown Campus in Ridgetown, Ontario. A four replicate, randomised complete block design was planted with each replicate consisting of one row per variety. Each row was 3 metres long and spacing between rows was 0.75 metres. The plants were spaced 0.075 metres within the rows. The number of plants per variety was 80 X 4 replicates.
