Registration of 'Pennell' lentil.

'Pennell' (Reg. no. CV-19, PI 634209) is a large-seeded yellow-cotyledon lentil (Lens culinaris Medik.) developed by the USDA-ARS in cooperation with the Washington Agricultural Research Center, Pullman, WA, the Idaho Agricultural Experiment Station, Moscow, ID, the North Dakota Agricultural Experiment Station, Fargo, ND, and released in 2003. Pennell has absence of seed coat mottling, upright plant habit and high yield.

Pennell, selection LC460197, originated as an F6 selection from the cross of LC660194/'Brewer' made in 1990 to combine large seed size with upright plant habit. LC6600194 is a selection from PI 299321 made in 1986 for large seed size and upright plant habit. Brewer (PI 508090) was released in 1984 as a large-seeded, yellow-cotyledon, high-yielding cultivar (Muehlbauer, 1987). The cross was advanced to the [F.sub.6] by the bulk method, single plant selections were made in 1993, and grown in progeny rows in 1994. The [F.sub.7] progeny-row that led to the development of Pennell was selected in 1994. Preliminary screening tests for yield and plant traits were conducted in 1995 and Pennell was entered in the preliminary yield trial at Pullman in 1996. Pennell was evaluated in advanced yield trials at 15 site-years from 1997 to 2000. The average yield of Pennell was comparable to Brewer; however, Pennell yielded 9.1% higher than 'Mason' (PI 619099) (Muehlbauer, 2002), the comparable cultivar for seed size.

Compared with Brewer, Pennell was 1cm taller, flowered an average of 2 d later, and matured 1 d later. Plants of Pennell are strongly branched at the base, which imparts a bushy structure that enables the canopy to remain somewhat erect during the growing season. Pennell has uniform large seeds (100 seeds weigh an average of 6.6 g compared with 6.0 g for Brewer and 6.5 g for Mason). Pennell seeds have yellow cotyledons and its light green seed coats lack mottling. These seed features should appeal to markets in the USA and internationally. Cooking time tests in 2000 and 2001 indicated that both Pennell and Brewer required 21 min for cooking.

Pennell had lower scores for virus infection, mainly pea enation mosaic, when compared with Mason. Scores for resistance to Aphanomyces root rot (caused by Aphanomyces eutieches Drechs.) were similar to those for Mason and Brewer.

Plant variety protection will not be sought for Pennell. Breeder and Foundation seed of Pennell will be maintained by the Washington State Crop Improvement Association under the supervision of the Department of Crop and Soil Sciences, College of Agriculture Research Center, Washington State University; and the USDA-ARS, Pullman, WA 99164-6434. Small quantities of seed of Pennell for research purposes may be obtained from the corresponding author for at least 5 yr. Recipients of seed are asked to make appropriate recognition of the source of Pennell if it is used in the development of a new cultivar, germplasm, parental line, or genetic stock.
