Abstract

‘Cedar Creek’ (Reg. no. CV-290, PI 700113) switchgrass (Panicum virgatum L.) was selected for increased winter survivorship for three cycles, using surviving plants from ‘Kanlow’. The first two cycles were conducted at multiple locations in Wisconsin, and the third cycle was conducted at the Cedar Creek Ecosystem Science Reserve, East Bethel, MN. All seed production and increases were conducted by either Illinois State University or the University of Illinois. Field evaluations of the third-cycle population were conducted at five locations in Wisconsin between 2017 and 2021, located within USDA hardiness zones 3–5. Field experiments were planted in both 2016 and 2017. Averaged over the five locations and all trial years, Cedar Creek had 91% ground cover, compared with 96% for Cave-in-Rock, 95% for Shawnee, and 91% for Liberty. Biomass yield of Cedar Creek averaged 12.17 Mg ha⁻¹, which was 20% higher than Liberty, 30% higher than Cave-in-Rock, 31% higher than Shawnee, and 520% higher than Kanlow. Cedar Creek is a high-biomass lowland-type of switchgrass and is the first lowland-type adapted to USDA hardiness zones 3–5. Cedar Creek was released to the public by USDA-ARS in 2021.

“雪松溪”柳枝稷注册

“雪松溪”(Reg.)不。选择CV-290, PI 700113)柳枝稷(Panicum virgatum L.)，利用‘Kanlow’的存活植株，增加了三个周期的冬季成活率。前两个周期在威斯康星州的多个地点进行，第三个周期在明尼苏达州东伯特利的雪松溪生态系统科学保护区进行。所有的种子生产和增加都是由伊利诺伊州立大学或伊利诺伊大学进行的。2017年至2021年期间，在威斯康星州的五个地点对第三周期种群进行了实地评估，这些地点位于美国农业部抗寒区3-5内。在2016年和2017年进行了田间试验。在五个地点和所有试验年份的平均值中，Cedar Creek的地面覆盖度为91%，而Cave-in-Rock的覆盖率为96%，Shawnee的覆盖率为95%，Liberty的覆盖率为91%。杉木溪的平均生物量产量为12.17 Mg ha−1，比Liberty高20%，比Cave-in-Rock高30%，比Shawnee高31%，比Kanlow高520%。雪松溪是一种高生物量的低地型柳枝稷，是第一个适应美国农业部抗寒区3-5的低地型。Cedar Creek于2021年由USDA-ARS向公众发布。

期刊介绍： The Journal of Plant Registrations is an official publication of the Crop Science Society of America and the premier international venue for plant breeders, geneticists, and genome biologists to publish research describing new and novel plant cultivars, germplasms, parental lines, genetic stocks, and genomic mapping populations. In addition to biomedical, nutritional, and agricultural scientists, the intended audience includes policy makers, humanitarian organizations, and all facets of food, feed, fiber, bioenergy, and shelter industries. The scope of articles includes (1) cultivar, germplasm, parental line, genetic stock, and mapping population registration manuscripts, (2) short manuscripts characterizing accessions held within Plant Germplasm Collection Systems, and (3) descriptions of plant genetic materials that have made a major impact on agricultural security. Registration of plant genetic resources, item (1) above, requires deposit of plant genetic material into the USDA ARS National Plant Germplasm System prior to publication.
