| 0 | PI 607513 | AS-A | Zea mays L. subsp. mays | Minnesota, United States | NC7 |  | | 1991 | DEVELOPED | | | | | | Breeding material | Yellow dent population developed from controlled six and eight-way crosses among 13 inbred lines (A90, A498, A508, A509, A513, CMD5, MS1334, ND203, W33, W59M, W65, W79A, W103). These crosses were randomly mated for six generations to produce the population. AS-A was used in a study of recurrent selection methods (Crop Sci. 11:658-661). AS-A is of AES300 maturity and has good stalk strength. | 1071504 | PI 607513 |
| 1 | PI 607514 | AS-B | Zea mays L. subsp. mays | Minnesota, United States | NC7 |  | | 1991 | DEVELOPED | | | | | | Breeding material | Yellow dent population developed from 12 inbred lines (A90, A498, A508, A509, A513, ND203, R5, V3, W33, W65, W79A, W103). Emphasis was placed on earliness in that W103 made up 5/16 of the base population. Controlled crossing among the inbred lines produced eight-way crosses which were randomly mated for six generations. AS-B has good stalk strength and is of AES200 maturity. | 1071505 | PI 607514 |
| 2 | PI 607515 | AS-D | Zea mays L. subsp. mays | Minnesota, United States | NC7 |  | | 1991 | DEVELOPED | | | | | | Breeding material | Yellow semident population developed from crosses involving eight inbred lines (A73, B14, CO106, ND255, Oh43, V3, WD, WF9). Selections from these crosses were randomly mated for six generations. The population was then subjected to several cycles of mass selection for early flowering and resistance to smut (caused by Ustilago maydis). AS-D is of AES100-200 maturity. | 1071516 | PI 607515 |
| 3 | PI 607516 | AS-DK(S)C3 | Zea mays L. subsp. mays | Minnesota, United States | NC7 |  | | 1991 | DEVELOPED | | | | | | Breeding material | Yellow floury population. Deep kernel variety of Peruvian origin, was crossed with 10 inbred lines (A90, A427, A495, A498, A509, A513, A556, CMD5, MS1334, ND203) to form AS-DK C0. Three cycles of recurrent selection for kernel depth were completed using the S1 progeny method, followed by three generations of random mating. Developed to provide a source of deep-kernel germplasm adapted to temperate latitudes. Kernels average 1.5 cm in depth. AES500 maturity. | 1071517 | PI 607516 |
| 4 | PI 607517 | AS-G | Zea mays L. subsp. mays | Minnesota, United States | NC7 |  | | 1991 | DEVELOPED | | | | | | Breeding material | Dark yellow flint population developed by crossing Netherlands and USSR introductions with early-flowering selections from early x late crosses among inbred lines of USA origin. These crosses were randomly mated for six generations. Very early population of AES100 maturity. | 1071528 | PI 607517 |
| 5 | PI 607518 | AS-3(HT)C3 | Zea mays L. subsp. mays | Minnesota, United States | NC7 |  | | 1991 | DEVELOPED | | | | | | Breeding material | Yellow dent population. AS-3(HT)C0 (formerly designated Minnesota Synthetic 3) was developed from random mating an eight-way cross of inbreds A73, A286, A295, A375, Oh5, Oh43, Oh51A, W22. Three cycles of half-sib recurrent selection for grain yield were completed with the tester Minnesota Synthetic 1 (Developed from intercrossing A71, A374, B164, Mich. 265, Mich. 401, SD100, W20, WR3). Effects of recurrent selection on genetic variability and performance of a synthetic maize variety were reported (Achmad Baihaki. 1973. M.S. Thesis, University of Minnesota, St. Paul). AS-3(HT)C3 is of AES500-600 maturity. | 1071529 | PI 607518 |
