0PI 693347CI 3AZea mays L. subsp. mays Maryland, United StatesNC7KERNELS2000DEVELOPED1945Breeding materialInbred CI.3A is a yellow inbred that traces its ultimate heritage to Boone County White and an Illinois 2-ear strain obtained by the USDA from H. A. Wallace in 1926. CI.3A differs from CI.3 by having a more intense yellow kernel color. CI.3A is somewhat more susceptible to root and stalk lodging than CI.3. It was released in 1945 to replace CI.3 in hybrids US 99, US 262, US 265, US 282, and US 357.1606091PI 693347

2PI 693398M14Zea mays L. subsp. mays Illinois, United StatesNC7KERNELS1964DEVELOPEDPRE 1932Breeding materialBen Moews (Moews Seed Company, Granville IL) developed M14 in the 1930s and donated it to the University of Illinois. It was one of the first commercially usable "Convergent Improved" inbreds. When released, M-14 was the only inbred listed in the Illinois Crop Improvement Association bulletin that was not produced by the USDA (from: http://www.moews.com/history.htm).

It was developed from a single cross (BR10 x R8) and was used in double cross hybrids in the 1930s and 1940s (Bob Lambert, 2011, personal communication)

Liu et al. 2003 (supplemental table S1: Pedigrees for Maize Inbreds) obtained three separate and conflicting pedigrees for M14 (a.k.a. Gn2; Don Duvick and Stan Jensen from Pioneer both indicated that Gn2 was derived from M14). (1) According to Bob Lambert at the University of Illinois (and Clarion Henderson of Illinois Foundation Seeds and Gerdes et.al., 1993), the pedigree is BR10 X R8, where BR10 is from Funk's Yellow Dent and R8 is from Texas Surecropper. (2) According to Tom Gocken at DeKalb, the pedigree is Lancaster X A, where A is a line from Funk's Yellow Dent. (3) According to records at Pioneer Hi-Bred, the pedigree is Lancaster X B21, where B21 is Fe2 X Steen 665. Ralph Hart of Moews Hybrids (Ben Moews developed M14 in the early 1930's) says that their existing records do not go back past 1966. Pioneer acquired Gn2 from Charlie Gunn of DeKalb Agricultural Research in 1935. DeKalb's records of it go back to 1932 (Tom Gocken, personal communication).

Another source states:"This line was developed in our corn breeding program and has been assigned a formal designation be cause it appears to have value in hybrid combination." Inbred Lines of Corn Released to Private Growers from State and Federal Agencies 4/18/60. Small kernel, 16-18 rows.

A description from Indiana in the Second Corn Improvement Conference Report of 1938 states: "Parent is BR10 X R8. It is from Ben Moews. It is early with fair pollen, short sturdy erect stalks with good roots. Ears are large with dark yellow smooth kernels.

The Fourth and Fifth Corn Improvement Conferences Report for 1940 and 1941 describes M14 at Illinois having dark green leaves, a stiff short stalk anad ears poorly covered. The poor ear trait is transmitted to crosses. Ears are low on the pang and ear shanks are long. Ear length is good and grain is of good quality. It combines will with WF9 and 187-2.

Plants raterh tall with ears of medium height; chlorophyll medium green; few suckers; strong root system but stalks tend to break after maturity; ears rather long, grain of fair quality" "Short stalk, long ears, stands fairly well. Excellent pollinator under the best conditions, but very temperamental. Also temperamental as to seed setting, though again under the right conditions sets well."1888188PI 151091

Plants usually have 13 to 15 leaves with 5 or 6 above the upper ear. Leaves dark green and erect. Moslty single eared. Silks green, glumes red, anthers red, stalk base dark red. Sheds pollen abundantly and is very productive. Highly resistant to corn earworm. A recovered strain of 33-16 with yellow endosperm color. The nonrecurrent parent was L317.

Mr. Pfister's inbred line 187-2 was developed from the Krug variety. The inbred has short, stocky plants with long ears and long shanks. It contibutes good combining ability and lodging resistance to hybrids. It is highly susceptible to leaf blights.1879513PI 146372
