The present paper represents further studies on the inheritance of several forms of premature germination previously reported; the verification
of several hypotheses which had been tentatively presented; and
a study of new types more recently discovered. The studies reported here
were made at the CONNECTICUT EXPERIMENT STATION from 1921 to 1926
and at the TEXAS EXPERIMENT STATION from 1927 to 1929. Some of the
stocks used were found to be unadapted to Texas conditions and rather
than delay completion of the work until new stocks could be developed,
most of the F, progenies were grown in New Haven, the self-pollinated
ears being returned to Texas for classification. I take this opportunity of
thanking Doctor D. F. JONES and Doctor W. R. SINGLETON for their
kindness in growing and pollinating this F1 material. I wish also to acknowledge
the assistance of Mr. A. T. CHISHOLM in classifying some
54,000 individuals included in these studies.
