Variety Description

Variety used for comparison: '5700PR'

Summary: At the 5 to 9 tiller stage, 'HY995' has a semi-erect to intermediate growth habit whereas it is erect to semi-erect in '5700PR'. The sheath glaucosity on the 'HY995' flag leaf is medium whereas it is absent or very weak on the '5700PR' flag leaf. The culm of 'HY995' has weak curvature whereas '5700PR' has medium curvature. The lower glume of 'HY995' has a sloping to slightly sloping shoulder that is very narrow whereas the shoulder is slightly sloping to straight and medium width in '5700PR'. The kernel of 'HY995' has a light-red to red colour whereas that of '5700PR' has an amber colour. The width of the crease of the kernel of 'HY995' is medium to wide whereas it is narrow to medium in '5700PR'.

Origin & Breeding History: 'HY995' (experimental designation '04S3031-1') was developed from the cross of '99S3144-7' / '5701PR', made in Berthoud, Colorado, USA in 2004. In 2005, individual head selections were taken from an F2 population screened for height, maturity and disease resistance at the Syngenta Canada, Inc. breeding nursery in Rosebank, Manitoba. Single seed descent was used to advance these selections through F3 and F4 generations in the greenhouse and in the summer of 2006, F5 head-rows were individually bulked. In 2007, the individual bulks in the F6 generation were screened for agronomic performance and resistance to Leaf Rust, Leaf Disease Complex and Fusarium Head Blight and selected from nurseries in Rosebank and Souris, Manitoba. One of the bulk selections designated '04S3031-1' was selected and tested in research plots in 2008 and 2009. During the 2010 to 2012 growing seasons, '04S3031-1' was tested as 'HY995' in the High Yield Bread Wheat Cooperative trials for agronomic performance, disease resistance and quality parameters.

Tests & Trials: The trials for 'HY995' were conducted in Rosebank, Manitoba during the summers of 2012 and 2013. Plots consisted of 7 rows spaced 18 cm apart. The plot size was approximately 1.2 metres wide by 3.0 metres in length, containing 2400 plants per plot. There were 3 replications arranged in a RCB design. In 2012 and 2013, the measured characteristics were based on 20 measurements with the exception of 10 plant height measurements taken in 2012.
