Narrative
B77 is a yellow dent inbred line that was selected from Pioneer Two-Ear Composite (PHPRC), a synthetic developed by crossing southern prolific germ plasm and Corn Belt lines. Pioneer Two-Ear Composite [BS11(FR)C0] was used as one of the populations for the reciprocal full-sib selection program described by Hallauer (Crop Sci. 7:192-195; Crop Sci. 14:341-342). Selection for a two-ear plant type has given a genotype that produces good second ears on nearly 100% of the plants at densities up to 38,000 plants/ha. Pollen production is satisfactory, silks emerge 1 to 2 days after the first shedding of pollen, and seed set is good on both ears. Seed is relatively small and shallow dented. The line has intermediate resistance to first brood European corn borer and common fungus leaf diseases and high resistance to maize chlorotic dwarf, but it is moderately susceptible to maize dwarf mosaic. Evaluations for yield in single crosses in Iowa for 4 years have shown B77 to have the highest average general combining ability of all the lines included in the tests. Its contribution to root and stalk strength in hybrids is adequate, but not outstanding. Although the line is late in silk emergence, grain moisture at harvest shows evidence of a fast-drying characteristic in single-cross hybrids. Extensive evaluation has shown that B77 is adapted to southern and south-central Iowa. Maturity classification is late AES800. B77 was evaluated extensively and released because of potential value to the hybrid corn seed industry and for further use in breeding programs.
