‘Provena’ short-strawed hulless-seeded spring oat (Avena sativa L.) (Reg. no. CV-371, PI 595902), was developed cooperatively by USDA-ARS and the Idaho Agricultural Experiment Station. It was formally released by these agencies in June 2000. Provena is adapted to production throughout the western USA.
Provena is from a cross of ‘Pennlo’/PI 447276. Pennlo (GP-23) was developed by ARS scientists at Pennsylvania State University, University Park, PA, (Marshall et al.,1983). PI 447276, equivalent to ‘Yung 492’, originated in Inner Mongolia and was introduced to the USA from the Peoples Republic of China in 1980. The cross of Pennlo/PI 447276 was made by ARS scientists at Pennsylvania State University. Selections were made at Aberdeen, ID, from early generation seed shared with ARS scientists stationed at the University of Idaho Aberdeen Research and Extension Center. Provena originated at Aberdeen, ID, as a F4 head row selection in 1988 and was identified as 88Ab3073 before release. Breeder seed of Provena originated as a bulk from 100 uniform head rows grown at the Aberdeen Research and Extension Center in 1991, and subsequently grown at the Tetonia Research and Extension Center in 1992.
Provena is a midseason, short-strawed, hulless spring oat with equilateral panicles, hulless kernels, and blue-green foliage. Juvenile plant growth is erect. Occasional plants appear in the field that are typically 5 to 10 cm taller than the norm, but otherwise similar in appearance.
Provena was first tested in replicated trials in Idaho in 1990. It has been widely tested in both irrigated and dryland trials in Idaho and other western states since regional testing in the Uniform Northwestern States Oat Nursery was initiated in 1992. It also has been tested in trials in western Canada as well as the Cooperative Naked Oat Test, the latter including several locations in the Midwest, the eastern USA, and eastern Canada. Provena is the shortest strawed hulless oat cultivar currently available that is adapted to production in the western USA. It has a good yield record in Idaho and other locations in the West, especially compared to other short-strawed hulless cultivars. In six station-years of testing in irrigated trials at Aberdeen, ID, in 1993 through 1998, Provena averaged 5190 kg ha-1 in grain yield with an average of over 97% hulless kernels, resulting in a groat yield of about 5146 kg ha-1. Groat yields for other cultivars in the same trials were 5944 kg ha-1 for Monida, 5330 kg ha-1 for Ogle, 5696 kg ha-1 for Paul, and 3824 kg ha-1 for Pennuda. Monida and Ogle are hulled cultivars and Paul and Pennuda are hulless cultivars. In 4 station-years of testing in irrigated trials at Tetonia, ID, in 1995 through 1998, Provena averaged 4190 kg ha-1 and Paul averaged 3677 kg ha-1. In 4 station-years of testing in dryland trials at Tetonia, ID, in 1995 through 1998, Provena averaged 2760 kg ha-1 and Paul averaged 2570 kg ha-1.
Provena is shorter in height than Monida, ‘Otana’, and Paul, (13, 23, and 23 cm, respectively, in trials at Aberdeen). Provena is superior to both Otana and Monida in lodging resistance. Provena headed about two days earlier than Monida. Test weight is a lesser issue in hulless oats relative to hulled cultivars, but, nevertheless, Provena has very good test weight, averaging 622 kg m-3 in 6 yr of testing under irrigation at Aberdeen. The groat protein content of Provena is typically equal or superior to other adapted oat cultivars in trials in southern Idaho, averaging 18.4% under irrigation at Aberdeen (seven trials), 18.0% in irrigated trials at Tetonia (four trials), and 21.1% in dryland trials at Tetonia (four trials).
Provena offers the option of a well-adapted, short-strawed oat for producers interested in hulless oat production and marketing in Idaho and in other western states. Provena is expected to favorably compete with existing spring oat cultivars, especially hulless oat cultivars, in irrigated and higher rainfall dryland environments in Idaho and in other western states with its short straw and good lodging and shattering resistance, combined with its good expression of the hulless trait. Producers should be aware the groats of hulless oat cultivars typically have a high frequency of exposed trichomes or hairs that cause skin irritation during harvest and handling operations. Hulless oats also have a greater tendency to plug some handling equipment.
Genetic material of this release has been deposited in the USDA-ARS National Plant Germplasm System where it will be available for research purposes, including development and commercialization of new cultivars. Breeder and Foundation seed of Provena will be maintained by the Idaho Agricultural Experiment Station, Foundation Seed Program. Requests for Breeder and Foundation seed should be directed to the Coordinator, Foundation Seed Program, Kimberly Research and Extension Center, 3793 N 3600 E, Kimberly, ID 83341.
