Abstract

Eighty-seven groundnut (Arachis hypogaea L.) genotypes were tested in the field for resistance to rust caused by Puccinia arachidis over two years. Resistant germplasms belonged to ICGS (FDRS) category, specifically nos. 4, 10, 23, and 43. Of these, ICGS (FDRS)-4 and 23 and five moderately resistant cultivars (ICGS-47, ICGS(E)-18 and C-115, 99, and 1706) showed stability of resistance.
