FOREWORD 
Yitis rotundifolia, tlie Muscadine grape, lias been the subject of in¬ 
vestigation by the Department of Horticulture of the North Carolina 
Agricultural Experiment Station for a number of years, with a view 
to the determination and the discovery of facts relating to its origin, 
its characteristics, and the laws which govern their transmission. The 
results of such research should serve as an addition to our plant-breed¬ 
ing knowledge and help to form a substantial basis for the improvement 
of this class of grapes. 
The results which have been accomplished are set forth in the follow¬ 
ing bulletins: 
1. “Scuppernong and Other Muscadine Grapes: Their Origin and 
Importance/’ by E. C. Reimer, Bulletin No. 201, N. C. Agr. Exp. Sta¬ 
tion. 1909. 
2. “Self-Sterility of the Scuppernong and Other Muscadine Grapes,” 
by F. C. Reimer and L. R. Detjen, Bulletin No. 209, N. C. Agr. Exp. 
Station. 1910. 
3. “Breeding Rotundifolia Grapes: A Study of Transmission of 
Character,” by F. C. Reimer and L. R. Detjen, Technical Bulletin No. 
10, N. C. Agr. Exp. Station. 1914. 
The present bulletin deals with the problems of transmission of sex 
and constitutes the fourth contribution to this series of reports of work 
accomplished. J. P. Pillsbury, 
Horticulturist.
