Abstract
One hundred and four sorghum genotypes were screened under field conditions for loose smut using
the hypodermic stem injection artificial inoculation method and laid on a randomized complete block
design with two replications. Results showed that, of the 104 sorghum genotypes screened for loose
smuts, there was marked reduction in growth parameters in 26 (diseased) plants compared to healthy
or non- infected (78) plants. Similarly, number of day to 50% heading as well as grain yield/hectare were
significantly (P<0.05) affected in loose smut infected plants than in healthy plants, with the former
usually having less number of days to heading, as well as less yield than the latter. However, day to
50% flowering was not significantly (P>0.05) affected even among the diseased plants. The present
study have confirmed the fact that in loose smut, plants showing symptoms usually matured earlier and
produced less grain yield but did not confirm the hypothesis that the affected plant flowers earlier than
the healthy ones.
