0PI 634206Mo48Zea mays L. subsp. mays Missouri, United StatesNC7KERNELS2003DEVELOPEDBreeding materialDark green, medium-wide leaf blades angled open at about 60 degrees. Cob white, anthers yellow, trace color on the glumes and no glume bar. Has 19 to 21 tassel branches with a 23 cm spike. Has few tillers and floral synchrony is good. In 1999, at least as resistant to European Corn Borer as the resistant checks in replicated trials in MO, NE, IA, and MS. In 2002, tested for reaction to ECB2 damage in three replication in 10 tests in MO, MS, NE, IA,IL, OH, and DE for a total of 11 ECB1 locations evalued and 10 for ECB2. Mo48, Mo49, B73, Mo17, Mo47 (resistant check) and DE811 (resistant check) had 13.1, 10.9, 35.4, 28.2, 11.2, and 22.6 cm of stalk tunneling, respectively. This line responded better for yield on Mo17 tester (two yrs. and five MO trials-18 replications total) and its hybrids are more resistant to ECB2 damage than B73/Mo17 (5.7 cm and 4.1 cm vs. 8.4 cm, respectively).1649989PI 634206
1PI 634207Mo49Zea mays L. subsp. mays Missouri, United StatesNC7KERNELS2003DEVELOPEDBreeding materialMedium green leaves possibly with a lesion mimic syndrome. Leaves medium in width and angled upright at about 30 degrees. Cob white, anthers purple, glumes striped and there is a glume bar. Has 5 to 11 tassel branches with a 30.5 cm spike. Sometimes produces a few tillers and silking is slighly delayed. In 1999, at least as resistant to European Corn Borer as the resistant checks in replicated trials in MO, NE, IA, and MS. in 2003, tested for reaction to ECB2 damage in three replication in 10 tests in MO, MS, NE, IA, IL, OH, and DE for a total of 11 ECB1 locations evaluated and 10 for ECB2. Mo48, Mo49, B73, Mo17, Mo47 (resistant check) and DE811 (resistant check) had 13.1, 10.9, 35.4, 28.2, 11.2, and 22.6 cm of stalk tunneling, respectively. Responded better for yield on a Mo17 tester (two yrs. and five Missouri trials-18 replications total) and its hybrids are more resistant to ECB2 damage than B73/Mo17 (5.7 cm and 4.1 cm vs. 8.4 cm, respectively).1649990PI 634207
