Zea mays

Iowa, United States
Historic
2003
DEVELOPED
2002
Breeding material
Vigorous inbred line developed from the F2 population developed from a cross of B97 and B99. Flowers about 80 days after planting and would be classified for the AES 700-800 Maturity Group. Hybrids that include B116 as one parent have exhibited consistently high grain yield in trials conducted in Iowa and the North Central Region. Yellow, dent kernels are produced on large ears with pink-to-red cobs. Yield of B116 per se is greater than for most parental inbreds. Above average tolerance to 1st and 2nd generation European corn borers (Ostrinia nubilalis Hubner), northern corn leaf blight (Exserohilum turcicum Pass.), and gray leaf spot (Cercospora zeae-maydis Tehron and Daniels).

1992
DEVELOPED
Breeding material
Developed from population of Iowa Corn Borer Syn. No. 1 (BSCB1) after nine cycles of reciprocal recurrent selection [BSCB1(R)C9-2]. Tall, vigorous line with above average resistance to first- and second-generation European corn borer (Ostrinia nubilalis) infestation, excellent stalk and root strength, and above average stay green after physiological maturity of grain. Ears have 14 rows of large, yellow dent kernels on intermediate length ears with red cobs. Tassels good pollen producers. Maturity classification is AES700

Breeding material
Endosperm yellow. Cob red. Relative maturity similar to C103 with better kernel type than C103. Easier to maintain in Missouri than C103. Resistance to leaf blight (Helminthosporium turcicum) and stalk quality similar to C103. Pollinates itself readily under semi-drought conditions. Maturity AES800.
