Many of the sorgo varieties used in the breeding work of the U. S. Department of Agriculture, centered at Meridian, Miss., do not notmally produce seed there. It is necessary to maintain viable seed supplies of these varieties for use as breeding material. Seed increase, however, in the greenhouse in the winter is very limited and rather expensive. Previous experience had indicated that fall planted sorghum at the Division's station at Canal Point, Fla. would produce an abundance of seed early enough in the spring to be used at Meridian that same spring. The short days coupled with the mild winters there caused even the very late varieties to bloom and develop seed. It was necessary, however, to determine the best time in the fall to plant sorghum in order to have seed mature in March or April the next spring. Consequently, a date of planting test was outlined and conducted at Canal Point, Fla. in order better to utilize that Station in the breeding program and to obtain some information on the differential response of sorgo varieties to that environment
