Registration of 'Manny' barley.

'Manny' barley (Hordeum vulgare L.) (Reg. no. CV-314, PI 633981) is six-rowed, hulled, and rough-awned spring barley with strong straw that is adapted to western Canada. Manny was developed at the Field Crop Development Centre (FCDC) of Alberta Agriculture, Food and Rural Development (AAFRD), and was approved for registration in February 2003 by the Prairie Registration Recommending Committee for Grain--Barley and Oats Subcommittee. Manny was registered in Canada (Reg. no. 5675) on 21 July 2003. Manny was named after Manuel (Manny) J. Cortez, the late FCDC germplasm scientist involved in the early development of this and many other barley cultivars from FCDC. Manuel worked at FCDC for 14 years developing and evaluating a wide range of germplasm and maintaining the germplasm database.

Manny was evaluated as H90013004Z in the FCDC-AAFRD barley field tests and starting in 2001 as BT 562 in the Western Co-operative Six-Rowed Barley Tests. Manny was derived from the 1990 cross of lines BT 538 and BT 636. The line BT 538 was derived from a [F.sub.2] introduction into the FCDC breeding program from the International Maize and Wheat Improvement Center (CIMMYT) in 1979. Through generations, this introduction was tested, screened, and selected under the designation M78156005. The pedigree of M78156005 is 11012.2-MZQ(PRO-TOLIxCER2-TOLI/DWG1/API/POR/ C58.1-4407-1Y). The line BT 636 originates from Agriculture and Agri-Food Canada (AAFC) at Lacombe. The pedigree of BT 636 is LA659-207/BT 324. LA659-207/BT 324 is a sister line of 'Diamond' (Kaufmann and Kibite, 1985), originating from the cross of 'Galt'/'Unitan' (Harder and Legge, 2000; Martin et al., 1991). Galt (Wells, 1967) is a Canadian cultivar and Unitan (Eslick and Hockett, 1965) is an introduced cultivar from the United States. BT 324 is from the cross of NDB 135/Br. 6355-14. NDB 135 is a North Dakota six-rowed feed barley developed in the 1960s that was noted then for its good leaf disease resistance. The pedigree of NDB 135 is Dickson/ 3/CIho 4738//Traill/UM 570 (Peterson et al., 1968; Lambert, 1958). The pedigree of UM 570 is Newal (CIho 6088)/Peatland (CIho 2613)//Montcalm (CIho7149). Br. 6355-14 is a line developed in 1963 at AAFC Brandon (likely a six-rowed malt cross) whose pedigree has been lost.

A modified pedigree-bulk breeding procedure was used to propagate early generation progeny of the breeding line H90013. The [F.sub.1] generation was grown as increase plots in a winter nursery (1990-1991) near El Centro, CA. The [F.sub.2] seed from California was grown in field plots at FCDC, Lacombe in 1991. Seeds from approximately 500 randomly selected spikes from [F.sub.3] plants were harvested in bulk and sown in the California winter nursery. The [F.sub.4] to [F.sub.6] generations were grown as bulk plots at FCDC from 1992 to 1994. The [F.sub.6] generation plants were selected to grow out as 200 individual [F.sub.7] headrows. The line H90013004Z was selected from the headrows based on grain yield, test weight, 1000-kernel weight, lodging resistance, and resistance to diseases such as scald [caused by Rhynchosporium secalis (Oudem.) J.J. Davis] and smuts (caused by several Ustilago spp.). Manny has good feed quality (determined by near-infrared spectroscopy) such as digestible energy and digestible proteins. The line H90013004Z was first yield tested in a single replicated trial located at FCDC in 1996, followed by replicated yield trials at multiple locations from 1997 to 2001. Purification of H90013004Z took place during this time, resulting in 196 [F.sub.12] headrows that were selected to form the Breeder seed.

Manny is a medium height cultivar with strong straw and lodging resistance. Manny has a juvenile growth habit between erect and intermediate. As a juvenile plant, it has a wide, long, and upright flag leaf with white auricles. It has short spikes with long awns that are slightly purple tipped. The kernels of Manny are short in length and medium in width with clasping lodicules and incomplete horseshoe-shaped basal markings.

In the 2001 and 2002 Western Co-operative Six-Rowed Barley Test, average grain yield for Manny from 34 locations was 4467 kg [ha.sup.-1] compared to 4538 kg [ha.sup.-1] for 'AC Lacombe' (Kibite, 1994) and 4854 kg [ha.sup.-1] for 'AC Rosser' (Therrien, 1998). From the FCDC yield data based on 50 station years, Manny had an overall mean yield of 6766 kg [ha.sup.-1] compared to 6522 kg [ha.sup.-1] for AC Lacombe. Manny out-yielded the check cultivar AC Lacombe by 4 to 9% in the Western Black Soil Zone (five locations) in the 2001 and 2002 Western Co-operative Six-Rowed Barley Test. This trend was reflected in the High Yield Class (6.0-8.0 t [ha.sup.-1]) of FCDC Tests based on 27 station years. Manny matures in 90 d. This is 1 to 3 d earlier than AC Lacombe or AC Rosser. This is based on the average of 44 station years at FCDC tests and 27 locations in two years of the Western Co-operative Six-Rowed Barley Test. Results of the FCDC Tests show Manny had an average 1000-kernel weight of 38.0 g compared to 41.6 g for AC Lacombe (29 station years), and a test weight of 61.5 kg [hL.sup.-1] (49 station years), which is similar to AC Lacombe. Manny had a higher plump seed percentage of 69% compared to 59% for AC Lacombe. The biomass yield (taken at the soft dough stage for ensiling) of Manny (12 557 kg [ha.sup.-1]) was higher compared to that of AC Lacombe (11 651 kg [ha.sup.-1]) by 7% in four station years at FCDC. Manny shows better water use efficiency than the moderately drought-tolerant check cultivars AC Lacombe and 'Harrington' (Harvey and Rossnagel, 1984). The water-use efficiency (the ratio of dry matter production to water consumption) was determined from simulated rain shed experiments that were conducted at the FCDC. Manny showed a tendency of yielding relatively higher dry matter compared to the check cultivars under simulated drought conditions.

Manny has good field resistance to scald, as shown in combined data from the Western Co-operative Six-Rowed Barley Test and CIMMYT. In Mexico under high scald pressure, BT 562 was rated as R (resistant) in both 2000 and 2001, and TR (trace resistant) in 2002. In inoculated tests for smut in 1996 to 1999 at FCDC, H90013004Z was shown to be resistant to loose smut [caused by Ustilago nuda (Jens.) Rostr.]. In the Western Co-operative Six-Rowed Barley Tests, BT 562 had good resistance to covered smut [caused by U. hordei (Pers.) Lagerh.]. Manny has moderate resistance or tolerance to false loose smut [caused by U. nigra Tapke (syn. U. avenae (Pers.) Rostr.)], and further testing has shown 60% of the lines to be resistant while the remaining lines are susceptible to loose smut. Manny is moderately susceptible to the both net form of net blotch (caused by Pyrenophora teres f. teres Drechs.) and the spot form of net blotch (caused by P. teres f. maculata Smedeg.). Manny is susceptible to common root rot [caused by Cochliobolus sativus (Ito & Kurib) Drechster ex Dastur.] and is moderately susceptible to stem rust (caused by Puccinia graminis f. sp. tritici Eriks & E. Henn.). Manny is susceptible to both spot blotch [caused by C. sativus (Ito & Kurib) Drechster ex Dastur.] and to Septoria speckled leaf blotch (caused by Septoria passerinii Sacc.). Manny is moderately susceptible to Fusarium head blight (scab) {mainly caused by Fusarium graminearum Schwabe [telemorph Gibberella zeae (Schwein.) Petch]}.
