abstract: Sweet sorghum (Sorghum bicolor (L.) Moench) is an important crop in Chad that plays an economic role
in the countryside were stalks are produced mainly for human consumption without any processing.
Unfortunately, very little information exists on its genetic diversity and brix content. Studies
performed in 2014 and 2015 showed that there were significant variations (p < 0.001) for all assessed
quantitative traits. Potential grain yield (0.12–1.67 t ha−1), days to 50% flowering (68.3–126.3 days),
and plant height (128.9–298.3 cm) were among traits that exhibited broader variability. Brix content
range from 5.5 to 16.7% across accessions, was positively correlated to stalk diameter and plant
height, but negatively correlated to moisture content in fresh stalk and potential grain yield. Fresh
stalk yield range from 16.8 to 115.7 Mg ha−1, with a mean value of 58.3 Mg ha−1 across accession.
Moisture content in fresh stalk range from 33.7 to 74.4% but was negatively correlated to fresh
stalk yield. Potential sugar yield range from 0.5 to 5.3 Mg ha−1 across accession with an average of
2.2 Mg ha−1. Theoretical ethanol yield range from 279.5 to 3,101.2 L ha−1 across accession with an
average of 1,266.3 L ha−1 which is significantly higher than values reported under similar semiarid
conditions. Overall, grain yields were comparatively low. However, two accessions had grain yield of
more than 1.5 t ha−1; which is greater than the average 1.0 t ha−1 for local grain sorghum varieties in
Chad. These could have multi-purpose uses; grains, sugar and bioenergy production.
