Abstract ‘Grasslands Lakota’ prairie grass (Bromus
catharticus Vahl.) was selected from 72 Bromus breeding lines
and accessions evaluated in Oregon and Pennsylvania, United States, between
1995 and 1998. The aim was to produce a cultivar of B. catharticus
that was better adapted to the northern regions of the United States than
the currently available cultivar ‘Grasslands Matua’. From 1996, all 72 lines
were screened in New Zealand for seed production, and for uniformity and
distinctness. In March 1998, the data at all three sites were collated and
Cb 1307 was selected as the preferred line. It was discovered in a sandframe
at Palmerston North, but the ancestry is unknown. Since 1998, this selection
has been certified and commercialised, and has been named ‘Grasslands Lakota’.
(In the United States it will be registered simply as ‘Lakota’.) It was given
Plant Variety Rights in New Zealand in 1999 and Plant Variety Protection
in the United States in 2001. Compared with the standard New Zealand cultivar
‘Grasslands Matua’, ‘Grasslands Lakota’ is less erect, and later to head.
It also has a wider and more open crown, a feature that may help to explain
the much lower susceptibility to powdery mildew (Blumeria graminis
(DC) Speer) in the United Sates.
Keywords ‘Grasslands Lakota’; prairie grass; Bromus
catharticus Vahl.
