FLORES-NAVEDA, Antonio et al. Agronomic performance of sorghumseed production lines. Agron. Mesoam [online]. 2013, vol.24, n.1, pp.111-118. ISSN 2215-3608.

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.
