Registration of ‘Price’ Barley

Abstract

Registration of 'Oklee' Wheat relatively early maturing and produces spikes 1.3 d earlier 'Oklee' is a hard red spring wheat (Triticum aestivum L.) than 2375 and 0.6 d earlier than Oxen (PI 596770), the most (Reg. no. CV-963, PI 634553) developed and released by the widely grown cultivar in Minnesota since the late 1990s. Oklee Minnesota Agricultural Experiment Station in cooperation is a semidwarf cultivar and averages 75 cm, the same height with USDA-ARS in January 2003. It was named after a town as Oxen, and is 3 cm shorter than 2375 in Minnesota trials. in its region of adaptation in northwest Minnesota. Oklee was In 35 Minnesota trials conducted from 1998 through 2002, released on the basis of its high grain yield, high grain volume Oklee yielded 3664 kg ha Ϫ1 compared to 3482 kg ha Ϫ1 for weight, high grain protein content, and early maturity. In addi-2375 and 3825 kg ha Ϫ1 for Oxen. Oklee was evaluated in tion, Oklee has moderate resistance to Fusarium head blight 29 environments in the Uniform Regional Hard Red Spring (FHB, caused primarily by Fusarium graminearum Schwabe). Wheat Nursery in 1998 and 1999 and yielded an average of Oklee was derived from the cross '2375'/SBF0670, made 3456 kg ha Ϫ1 compared to an average of 3470 and 3503 kg by the former Pioneer Hi-Bred spring wheat breeding program ha Ϫ1 produced by the check cultivars, 2375 and Verde (PI in the USA. The cultivar 2375 (PI 601477, syn. Pioneer 2375) 592561, Busch et al., 1996), respectively. Oklee has moderately has the pedigree Olaf//Era/Suqamuxi 68/3/Chris/ND487//Lark strong straw and a lodging rating of 2.3 when scored on a and was widely grown in Minnesota during the mid-1990s due scale of 0 (erect) to 9 (lodged) in 21 environments at which to its moderate resistance to FHB. SBF0670 is an unreleased lodging occurred from 1998 thru 2002. By comparison, the line whose pedigree contains hard red spring lines once promicultivars 2375, Oxen, and Verde had lodging ratings of 3.5, nent in the region including 'Chris' (CItr 13751, Heiner and 2.6, and 2.1, respectively. Johnston, 1967), 'Era' (CItr 13986, Heiner and McVey, 1971), Oklee has moderate resistance to FHB in misted, inoculated and 'Butte'. field nurseries, similar to the resistance of 2375. In 11 FHB The F 2 population producing Oklee was selected for leaf nurseries from 1998 through 2001, Oklee averaged 23.6% disrust (caused by Puccinia triticina Eriks.) and stem rust (caused eased spikelets, 16.7% visually scabby kernels (VSK), and by Puccinia graminis Pers.: Pers.) resistance in a field planting 8.8 mg kg Ϫ1 of the mycotoxin deoxynivalenol (DON). The at St. Paul in 1993. The F 3 generation was advanced by single cultivar 2375 averaged 22.7% diseased spikelets, 17.5% VSK, seed descent in a greenhouse. The selection resulting in Oklee and 9.8 mg kg Ϫ1 DON. In the same trials, the resistant check was selected from a single plant in an F 4 headrow in 1994 and 'BacUp' (PI 596533, Busch et al., 1998) and the susceptible this seed was increased in a winter nursery in Arizona during check ...

Registration of ‘Doyce’ Hulless Barley

“…On average (14 station years), head emergence of Doyce is similar to that of ‘Wysor’, 3 d later than hulless cultivar H585, 2 d later than ‘Nomini’ and ‘Price’, and 5 d later than ‘Callao’ (Starling et al, 1987; 1994; Price et al, 1996b; Brooks et al, 2005). Average (10 station years) plant height of Doyce (81 cm) is similar to that of Price, 5 cm shorter than H585, 18 cm shorter than Nomini, and 5 cm taller than Callao.…”

Registration of ‘Thoroughbred’ Barley

“…On average (22 station years), head emergence of Thoroughbred in Virginia is 2 d later than ‘Wysor’ and 4 d later than ‘Nomini’ (Starling et al, 1987, 1994). Average (19 station years) plant height of Thoroughbred (91 cm) is 8 to 10 cm taller than ‘Callao’ and ‘Price’, and 8 to 10 cm shorter than Wysor and Nomini (Price et al, 1996; Brooks et al, 2005). On the basis of Belgian lodging score (0.2 = no lodging, 10 = completely lodged), average (24 station years) straw strength of Thoroughbred (1.4) is similar to those of Price (1.5) and Nomini (1.7), and better than those of Wysor (2.8) and Callao (5.0).…”

Registration of ‘Secretariat’ Winter Barley

“…Marchal]. Secretariat has expressed higher levels of resistance to leaf rust than the cultivars ‘Atlantic’ (PI 665041; Brooks et al, 2014), ‘Price’ (PI 632708; Brooks et al, 2005a), and ‘Callao’ (PI 592800; Price et al, 1996) and is more resistant than ‘Thoroughbred’ (PI 634933; Brooks et al, 2005b) to powdery mildew and leaf rust. In addition to good kernel physical characteristics, Secretariat has a mean starch concentration (56.9%) similar to Price and Callao and a protein concentration (9.8%) similar to Atlantic, Thoroughbred, Price, and Callao.…”
