Narrative
BS20(S)C2 is a yellow dent synthetic that was derived from BS20 (originally designated as Iowa Late Rootworm Synthetic). A large number of inbred lines were evaluated as inbreds per se and in hybrid combinations for corn rootworm tolerance and several root traits. Twelve inbred lines were selected as parent lines for a late synthetic, BS20, to be used in further studies of resistance or tolerance to corn rootworms. These lines were: B14A, B53, B57, B64, B67, B69, A73, N6, N28, R101, HD2286 (BSSS sel.), and 38-11. As a group, these inbred lines would contribute root characteristics believed required in a maize population for good tolerance to corn rootworm larval damage. Six of these lines originated from BSSS (Iowa Stiff Stalk Synthetic), and B64 derived from a backcross program in which B14 was the recurrent parent; consequently, BS20CO obtained more than 55% of its genes from BSSS. An evaluation of BS20CO in a synthetic diallel showed that it was superior in general combining ability for yield and resistance to root and stalk lodging (Euphytica 25:117-127). Recurrent selection based on the evaluation of S1 lines in replicated experiments was used for two cycles, resulting in the C2 population. The first cycle evaluation was of 234 S1 lines, and 24 were selected for recombination to give the Cl. In the second cycle, 123 S1 lines were evaluated and 20 were selected and recombined to give the C2. Traits evaluated in both cycles were resistance to root lodging, root damage by larval feeding, root system size, and secondary root development. The C2 population has a vigorous plant with an extensive root system; thus, it is expected to be an excellent source from which breeders may develop inbred lines. The maturity classification is approximately AES800.

Description:
BS20(S)C2 was developed by two cycles of S1 selection in BS20 (originally called Iowa Late Rootworm Synthetic) that was formed by intermating 12 inbred lines: B14A, B53, B57, B64, B67, B69, A73, N6, N28, R101, HD2286 (BSSS sel.), and 38-11.
