Subject: SWEET SUDAN FACTUAL DATA 
AND SPECIFIC ADVANTAGES 
GENERAL: Sweet Sudan is a new variety of Sudan Grass developed 
by the Texas Agricultural Experiment Station through hybridizing 
Leoti sweet sorghum and Common Sudan Grass. After crossing the 
two parents, appropriate backcrosses and selections were made to 
incorporate into the new variety the sweet and juicy stem, non- 
shattering seed, disease resistance, and sienna glume color of the Leoti 
parent while at the same time retaining the grassy characteristics of 
Sudan Grass. Sweet Sudan is quite resistant to several foliage diseases 
common to the sorghums, although it is not as resistant as Tift Sudan. 
It is resistant to chinch bugs and also more resistant to charcoal rot 
than Common Sudan. Sweet Sudan is slightly later than Common, 
which, together with its sweet and juicy stalks and resistance to plant 
diseases, enables it to remain green and growing over a longer season, 
and to furnish more grazing of better quality. The palatability of graz- 
ing does not deteriorate with maturity so much as it does with Common 
Sudan, and the mature stalks, when cut for bundles, still remain 
palatable. Numerous grazing tests have demonstrated that the sweet 
and juicy characters make Sweet Sudan more palatable than Common 
Sudan. Livestock will graze down the heavier stems of Sweet Sudan 
before eating more than the tenderest leaves of Common Sudan. Thus 
there is more complete utilization of Sweet Sudan pasture with cor- 
responding greater and faster gains in livestock. 
The amount of weight gain or milk production on pasture is determined, 
largely, by the quantity of food consumed. A greater amount of Sweet 
Sudan can be consumed because of its high degree of palatability. Also, 
because of its palatability, a higher percentage of Sweet Sudan rough- 
age is consumed in comparison to Common Sudan.

profitable to feed. 
SEED DESCRIPTION: The distinc- 
tive sienna or reddish brown seed 
color of Sweet Sudan permits ready 
detection of Johnson Grass contami- 
nation and distinguishes it from 
other varieties of Sudan Grass. How- 
ever, Sweet Sudan seed may have a 
small percentage oe chocolate, ma- 
hogany, purple, or red Sudan seed 
and still be Sweet Sudan. At present 
plant breeders have not completely 
eliminated the dominant darker 
colors and genetical purity is not 
completely stabilized.
