Hordeum vulgare var. nudum
This variety of hulless barley is one of 9 heirloom varieties I trialed in 2014. The majority of the seed came from The KUSA Seed Society. These are all human consumption types that are easily threshed and dehulled. Most barley grown here in Northern Indiana is raised for animal feed, forage, and straw. Barley is fairly susceptible to cereal diseases brought on by wet conditions during flower pollination. Sumire Mochi had few issues with lodging.
Sumire Mochi is a spring planted, 6 row, variety from Japan. I chose this variety for the fact that it has a Glutinous trait which is rare in food-barleys. The kernels contain amylopectin starch, and are very nutritious. I found this variety to be one of the easiest to dehull using low-tek methods. The plants tiller (production of seed bearing side shoots) vigorously. I planted April 1st and harvested on July 3rd. Packets contain 7 grams (approx. 150 seed).
I planted a bed of Sumire Mochi in the Fall of 2017. It survived my winter with no problems and was the earliest harvested cereal grain I have ever had (June 12th). I do not know the cold hardiness for this variety in regions colder than Northern Indiana. I am a zone 5b. I would recommend planting a trial plot to see if this variety is suitable for your region.
