Abstract
A total of 5218 sorghum accessions was evaluated for their reaction to Puccinia purpurea in field experiments at Patancheru, India, during the post-rainy season of 1991-92; of these, 15 were rated 2 and 107 were rated 3-4 (on a scale of 1 to 5, resistant to susceptible) and were reassessed during 1993-94 in a field experiment where high humidity was maintained by sprinkler irrigation and resistance to Exserohilum turcicum [Setosphaeria turcica] was also evaluated. The 51 accessions that were rust-free or resistant to rust were rescreened during 1993-94 for resistance to both pathogens. Accessions IS 2300, IS 3443 C40, IS 31446, IS 18758 C242, IS 18758 C603 and IS 7023 demonstrated high levels of resistance to P. purpurea, with a further 9 accessions showing moderate to high resistance; these 15 accessions also showed moderate to high resistance to S. turcica. It is thought significant that 10 of these accessions are purple-coloured as sorghums with purple pigmentation are generally susceptible to rust.
