Inbred ND291 (Reg. no. PL-305, PI 631393) is a yellow-dent maize (Zea mays L.) inbred line developed at the North Dakota Agricultural Experiment Station, North Dakota State University (NDSU), Fargo, ND. ND291 was released 15 Feb. 2002 because of its potential value as germplasm source in pedigree-selection breeding programs for the northern Corn Belt. ND291 was selected from NDSM(M)C1, a strain of NDSM that has undergone mass selection for increased grain yield and reduced stalk and root lodging. Thirteen inbred lines of approximately AES100 to AES300 maturity were intercrossed to develop NDSM (Cross and Wanner, 1991). These inbred lines were chosen for good general combining ability for grain yield and stalk lodging resistance.

The original S₀ plant was selected from an isolated planting of NDSM(M)C1 and advanced ear-to-row by five generations of self-pollination. ND291 [NDSM(M)C1-1-1-1-1-1-2] was identified in a testcross with an early B14 tester (CM105 x A665) at the S₆ generation. Late-generation testing of ND291 was performed in 1996 (three locations), 1998 (five locations), 1999 (one location), 2000 (six locations), and 2001 (six locations) with commercial check hybrids (2–5) included in each trial. The average grain yield of two and three-way hybrid combinations with ND291 (7.45 Mg ha^-1) across environments were statistically (P ≤ 0.05) similar to commercial check hybrids (7.36 Mg ha^-1). Crosses that included ND291 had also statistically similar grain moisture at harvest (181.0 vs. 171.0 g kg^-1), similar root lodging (3.7 vs. 3.2%), and similar stalk lodging (4.0 vs. 3.0%). ND291 hybrids had 10 g kg^-1 greater protein concentration and equal starch and oil concentration than commercial checks. ND291 has shown good combining ability with early Iowa Stiff Stalk Synthetic (BSSS) and unrelated testers. Molecular marker analysis indicates that ND291 is related to the BSSS heterotic group. Grain yield data, however, indicate that ND291 combines well with BSSS testers.

ND291 is a vigorous line with above average seedling emergence percentage in cold soils. It has average resistance to early infection by eyespot (caused by Kabatiella zeae Narita and Hiratsuka) and common rust (caused by Puccinia sorgui Schwein). ND291 has a medium, green plant color and plants have a tendency to develop more than one ear. Inbred trials have shown that ND291 had high seed yield (3.5 Mg ha^-1), average moisture content at harvest, above average root lodging resistance (1.8%), and above average test weight when compared with 32 elite North Dakota inbreds. ND291 has loose husks and its ears have 14 to 16 kernel rows. ND291 has intermediate pollen shed and silks two days earlier than ND284 (NDSU, 1998, Carena, 2001), 3 d earlier than LH176, and 4 d earlier than A641 at Fargo, ND. Maturity classification is AES 200-300.

Breeder seed will be maintained by the North Dakota Agricultural Experiment Station and is distributed on request (50 kernels per request) from the corresponding author, Plant Sciences Department, North Dakota State University, Fargo, ND 58105. U.S. Plant Variety Protection for ND291 will be requested.
