Fertility Restoration and Yields in Maize1
- G. H. Stringfield2
Tests of 30 maize cultures in the Texas (cms) cytoplasm and segregating for fertility restoring genes gave a significant advantage in yield for the restored plants. Apparently normal fertiles and restored fertiles are different in productiveness. Working hypotheses are: (1) Restorer genes have a pleiotropic vigor-producing effect, (2) The Texas cytoplasm is superior to the more common United States cytoplasms, and (3) A heterotic genotype × cytoplasm interaction was operating.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
