Search by Crop & Variety: Lenetah Spring Barley


Overview

Lenetah is a two-rowed hulled, spring barley with a moderately lax spike which nods at maturity. The spike has smooth awns, long rachilla hairs, glume hairs that are banded, and glume awns equal in legnth to the glume. Laterals are sterile with a barbed apex. The kernel has white aleurone, veins with few barbs, and a crease that is open to slightly flaring. The hull is adhering, slightly wrinkled, tending to smooth. The rachis is glabrious to very few hairs.
‘Lenetah’ (Reg. No. CV-338, PI 652440) two-rowed spring feed barley (Hordeum vulgare L.) was tested under the experimental line number 01Ab11107 and developed by the USDA-ARS and the Idaho Agricultural Experiment Station. It was publicly released in December 2007 due to its superior yield across Idaho, but especially in northern Idaho, and under dryland conditions. It was evaluated in the three northern Idaho counties of Lewis, Nez Perce, and Latah and was named for these three counties. Lenetah was selected from the cross 94Ab12981/ 91Ab3148. 94Ab12981 has the pedigree 85Ab2323/‘Camas’. 85Ab2323 has the pedigree 79Ab19042/‘Crystal’ (Wesenberg et al., 1991) and is also a parent of ‘Tetonia’ (Obert et al., 2008). Camas, released by the University of Idaho but not registered, is a selection from the cross ND5976/ND7159. ND5976 has the pedigree ‘Maris Concord’/‘Klages’//ND2679-4, and ND7159 has the pedigree Klages/ND1244/3/ND2685/ND1156//‘Hector’ (Wells, 1973). 79Ab19042 is a selection from the cross Klages/ Hector. Klages (Wesenberg et al., 1974) was the two-rowed malting standard for many years and is the progenitor of the majority of current two-rowed malting barleys. 91Ab3148 has the pedigree ‘Gallatin’/‘Targhee’//‘Bowman’. Gallatin (Hockett et al., 1987) and Bowman (Franckowiak et al., 1985) are both two-rowed barleys that have performed well in Idaho. Targhee (Wesenberg et al., 1995) is a two-rowed spring feed barley best adapted to Idaho
Lenetah was developed using a pedigree selection procedure with all early generation population and line development done under irrigation at Aberdeen, ID. The cross between the two parents was made in January 1997; F1 seed was planted in April 1997 as a single 3.1-m row, and F2 seed was harvested in bulk. In April 1998, F2 seed was planted in four 3.1- by 1.4-m plots with 35-cm row spacing. Fifty F3 spikes, 5 from each of 10 rows, were harvested in 1998 and planted as individual progeny rows in 1999. Of these 50 F3 rows, 5 spikes from 10 superior rows, were individually harvested and planted in the spring of 2000 as F3:4 rows. Selection of superior rows was based on favorable maturity, height, and resistance to lodging.
Lenetah was evaluated across 43 location-years from 2004 to 2007. Of these, 21 were conducted by the ARS– Aberdeen breeding program. The remainder of the trials consisted of the WRSBN (10), WRDSBN (7), and University of Idaho Extension trials (5). Across all location-years, Lenetah yielded 103% of Baronesse. In dryland trials, Lenetah yielded 108.1% of Baronesse (Table 2) and 108.5% of Baronesse in trials conducted in northern Idaho and eastern Washington (Table 3). Under irrigation the performance of Lenetah has been equal to Baronesse, Tetonia, and Spaulding for yield, test weight, and plump kernels. In the 2007 WRDSBN and WRSBN trials, Lenetah ranked second and eighth, respectively. For within-year analyses, Lenetah was in the top statistical grouping in both the irrigated and dryland trials, while Baronesse was in the top statistical group only in the irrigated trials. Lenetah was in the top statistical grouping at all locations in the dryland test except at Hettinger, ND. In the irrigated trial, Lenetah and Baronesse were not in the top statistical group at Aberdeen, Langdon, ND, and Williston, ND. In addition, Lenetah was not in the top group at Powell, WY, and Saskatoon, SA. Baronesse was not in the top group at Idaho Falls, ID and Pullman, WA.
