 note = {A new inbred line, "Ho57", was developed as a parental line of silage maize. Ho57 was reg-istered as "Maize Norin Kou Oya 55" by the Japanese Ministry of Agriculture, Forestry and Fisheries in 2002. Ho57 was developed from Pioneer 3389, a hy-brid introduced from the U.S. Sib-crossing among the F_1 plants was performed, and S_0 seeds were obtained in 1986. Beginning with the S_0 line and continuing through to the S_6 generation, the inbred line was developed by selection and self-pollination in an ear-to-row system. Selection was made for improving the resistance to lodging and for improving ear performance. Ho57 is classified into the extremely late ma-turing group in Hokkaido. Its level of lodging resistance is high. Its resistance to northern corn leaf blight (Setosphaeria turcica) and southern corn leaf blight (Cochliobolus heterostrophus) is weak, but it has strong re-sistance to common smut (Ustilago maydis). The early growth of Ho57 is relatively good. Ho57 has a long and relatively thin stalk and medium ear height. The ear is long and rela-tively thin and has nearly 12 rows. The seed yield of Ho57 is high and its degree of pollen shedding is medium. Ho57 shows high com-bining ability with flint inbred lines. A new single cross hybrid cultivar, "Ohzora", was de-veloped using Ho57 as seed parent.},
