The 22 entry (1987) IPMSN was conducted at one location in India and two in West Africa. The across location mean smut severities for the test entries varied from 1-38% compared with 61% and 56% for the susceptible checks BJ 104 and ICMH 83202, respectively. Eleven entries were highly resistant with across location means of 1%, with a maximum of 2% at any one location. Six of the 11 smut resistant entries were also resistant to downy mildew (10%). In three years (1985-87) of multilocational testing at three to six locations every year, five of the common entries (ICMPS 100-5-1, ICMPS 601-6-1-4, ICMPS 601-6-3-1, ICMPS 601-6-6-3, ICMPS 900-9-3) showed mean smut severities of not more than 1% indicating stability of resistance in these entries. ICRISAT variety, ICMV 82132, derived from smut resistant composite, showed stability of resistance in three years of testing.
