Narrative
`Snowstorm' forage kochia (Bassia prostrata [L.] A.J. Scott) (synonym=Kochia prostrata [L.] Schrad.) was released in March 2012 by the USDA-ARS and the Utah Agricultural Experiment Station. Snowstorm was extensively compared to 'Immigrant', currently the only other forage kochia cultivar. In field comparisons, Snowstorm was similar to Immigrant in establishment and adaptation on semiarid rangelands, but was 64% taller (77 versus 47 cm), produced 68% more forage (2526 versus 1504 kg ha-1), had 22% higher protein content (79 versus 65 g kg-1), and 4% higher digestibility (674 versus 648 g kg-1) (P <= 0.05). DNA fingerprinting showed that Snowstorm, Immigrant, and experimental populations were genetically unique and distinct from each other. Snowstorm reaches full seed maturation in early- to mid-November in northern Utah (2 weeks earlier than Immigrant); however, is prone to seed shattering with approximately 50% seed shatter by early December. Snowstorm November seed yield (13.5 g per plant) was not significantly different than Immigrant (18.8 g per plant), but it's 100-seed wt (0.140 g) was higher (P <= 0.05) than Immigrant (0.086). Descriptively, Snowstorm would be classified as subspecies grisea versus Immigrant being subspecies virescens. Typical differences between the subspecies are evident including Snowstorm is more pubescent giving it a more grayish-blue appearance during the summer as opposed to the less-pubescent, darker green color of virescens types; and Snowstorm stems turn grayish green to yellow at seed maturity as opposed to the reddish color of virescens types. Ploidy analysis confirmed that Snowstorm is a tetraploid (2n=36) as opposed to diploid Immigrant (2n=18). Snowstorm is named as such because it is a new, taller, more productive, more nutritious forage kochia cultivar capable of increasing carrying capacity and nutritional content of fall and winter grazinglands, including where snow cover had limited forage kochia use in the past.

Pedigree
Description:
Snowstorm was developed as a synthetic cultivar using two cycles of phenotypic recurrent selection for stature, forage production, and adaptation to semiarid environments. Snowstorm traces it parentage to germplasm collected by Dr. Waldron in Uzbekistan (NPGS#, PARL 418), which included seed from remnant plants of the Uzbek landrace/population called Otavny. Otavny was described as an ecotype-specific population of the subspecies grisea, originating from the foothills of the Kirgizia region.
