Recurrent selection for divergent length of grain-filling period in the Colus maize population


, : Recurrent selection for divergent length of grain-filling period in the Colus maize population. Dissertation Abstracts International, B Sciences and Engineering 46(11): 3650B-3651B

Four cycles of recurrent selection for long and short grain-filling period (LGF and SGF, respectively) were applied. Material from each cycle was evaluated per se for 5 developmental traits, and testcrossed to inbred testers for the evaluation of a number of yield-related traits. The LGF and SGF selections diverged for several traits besides grain-filling period (GFP). The GFP of LGF selections increased by 0.36 days/cycle on a per se basis and 0.56 days/cycle on a testcross basis.

Understanding how the expression of transcription factor (TF) genes is modulated is essential for reconstructing gene regulatory networks. There is increasing evidence that sequences other than upstream noncoding can contribute to modulating gene...
