Discovery and utilization of sorghum genes (
Methods and composition for the production of non-flowering or late flowering sorghum hybrid. For example, in certain aspects methods for use of molecular markers that constitute the Ma5/Ma6 pathway to modulate photoperiod sensitivity are described. The invention allows the production of plants having improved productivity and biomass generation.
1. A method of screening a sorghum plant for a Ma5 allele comprising:
a) obtaining a sorghum plant; and
b) assaying the sorghum plant for a genetic marker genetically linked to the Ma5 allele, wherein said Ma5 allele is located on chromosome 2 between coordinates 67923811 to 68393290 bp.
2. The method of claim 1 , wherein the genetic marker is selected from the group consisting of sequence variants revealed by direct sequence analysis, restriction fragment length polymorphisms (RFLP), isozyme markers, allele specific hybridization (ASH), amplified variable sequences of plant genome, self-sustained sequence replication, simple sequence repeat (SSR) and arbitrary fragment length polymorphisms (AFLP).
