Narrative
The parallel selected tropical synthetic (TropicS) of maize is a collection of location-specific lineages derived from a common base population (TropicS-G0) which were systematically selected for early flowering time at eight locations spanning 28 degrees latitude in the USA. Seven tropical inbred lines were used as parents (CML10, CML258, CML277, CML341, CML373, Tzi8, Tzi9) to create TropicS-G0. These lines have high yield potential in topcrosses with U.S-adapted hybrids. However, due to their late flowering time in temperate environments, with long day-lengths during the growing season, the parental lines per se are poorly adapted to most of North America.After recombining the parental lines to create TropicS-G0, multiple generations of artificial truncation selection for early flowering time were performed at eight locations: Madison, WI; Boone, IA; Newark, DE; Clayton, NC; Lubbcok, TX; Caldwell, TX; Homestead, FL; and Santa Isabel, PR. To minimize genetic drift during selection, in each generation a large population was evaluated (10,000 plants) and a large number of individuals were selected and intercrossed (500 of the earliest flowering plants). The parallel selected TropicS collection was developed as a public resource for breeders and those seeking to investigate crop adaptation. This was developed as part of the Agriculture and Food Research Initiative Grant No. 2011-67003-30342 from the USDA-NIFA (Agriculture and Natural Resources Science for Climate Variability and Change Program).
