Sumario: The objective of the study was to evaluate the agronomic performance of A, B isogenic lines and R grain sorghum lines which restore androfertility of sorghum for grain production. This work was performed during the spring-summer 2010 in Marin Nuevo Leon under drip irrigation. Days to flowering, seed yield per plant, brix degrees and weight of 1000 seeds were measured. The statistical analysis with the benchmark test of averages with independent samples was realized in A, B sorghum lines to days to flowering, seed yield per plant, brix degrees and weight of 1000 seeds. In R lines the analysis of variance and DMS (P<0.05%) test was performed. A an B lines were not completely isogenic; there are A and R lines that may be crossed to produce commercial sorghum grain seed. B and R lines might be used as varieties and A, R parental lines planting splits were defined to produce hybrid sorghum seed.
