Search by Crop & Variety: Transit Spring Barley


Overview

‘Transit’ (Reg. No. CV-348, PI 660128), a two-rowed, spring, high ?-glucan barley, was developed and submitted for release in 2009 by the USDA-ARS, Aberdeen, ID in cooperation with the University of Idaho Agricultural Experiment Station. Transit is a selection from the cross 10/‘Azhul’//‘CDC Alamo’. 10 is a selection from composite cross XXXII. Azhul is a six-rowed, high beta-glucan cultivar released by the ARS and Arizona Agricultural Experiment Station and is the progenitor of most high beta-glucan cultivars and germplasm. Azhul was developed by the mutation of line 76-19-7 with diethyl sulfate. Line 76-19-7 has the pedigree CCXXXII/‘Arimont’//‘Westbar’. CDC Alamo, tested as HB340, has the pedigree SB85750/Azhul. Transit has a reduced yield potential compared with the best feed and malting types, but its high level of beta-glucan provides enough added value to allow it to be economically competitive with current malting-barley cultivars. The release of Transit will provide producers with a variety having improved yield potential and beta-glucan content compared with the current varieties CDC Alamo and Azhul. Transit is expected to be adapted to both irrigated and rainfed regions in Idaho.
Across 18 locations from 2007-09, ten rain-fed and eight irrigated, Transit averaged 111% of CDC Alamo and 66% of Baronesse. Across 12 locations from 2007-09, size of both irrigated and rain-fed, Transit averaged 72% of Salute. Across ten irrigated locations in 200709, Transit averaged 116% of CDC Alamo and 70% of Baronesse. Across seven irrigated locations from 2008-09, Transit averaged 77% of Salute. Across eight rain-fed locations from 2007-09, Transit averaged 103% of CDC Alamo and 60% of Baronesse. Across seven rain-fed locations from 2008 -09, Transit  averaged 64% of Salute.
For Maturity, Transit  is similar to CDC Alamo, as both averaged 185 to heading. Transit was significantly later than Baronesse which averaged 180 days, and Salutre which averaged 179 days. Straw strength is similar to CDC Alamo, Baronesse, and Salute, as none had significant levels of lodging.
It is requested that appropriate recognition of source be given when this cultivar contributes to research or development of new germplasm or cultivar.
