Narrative
Recurrent selection for field cold-tolerance in early spring plantings and earliness of silking for 4 cycles was followed by 3 cycles of progeny test selection using seedling growth in growth chambers at 10 deg. C (4.5 deg.-15.5 deg. daily range). Some of the latter tests were for general combining ability for cold-tolerance in diallele and topcrosses, including the use of the Swiss variety Rheintaler. Some of these topcrosses were incorporated into the breeding pool, and the result of this recombination became ESCT-1 (E=Colorado, S=Synthetic, CT=Cold Tolerant). The Syn 1 generation was produced in 1978 and Syn 2 in 1979. This synthetic is about 80 day relative maturity and has some susceptibility to lodging.

Pedigree
Description:
During 1969-1978 several cycles fo recurrent selection were performed at Colorado State University on a germplasm base of U.S., Andean, and European corn and named Cold Tolerant Composite, CTC-1. Phenotypic recurrent selection from 1969-1978 resulted in a new synthetic.
