Abstract

The study aimed to obtain sorghum mutant lines from the Numbu variety resistant to 3 major diseases (leaf rust, leaf spot, and anthracnose). The research was conducted at the ICERI Experimental Garden. The treatments were arranged using a Randomized Block Design with 3 replications with materials tested were five mutant lines derived from a Numbu variety (lines MM-5, MB-3. MB-5. MM-3, MM-4) and resistant comparison varieties (Kawali and Numbu) and check susceptibility lines (Super 2 and line SRN48-1) as a comparison for each disease. The results showed that the five test genotypes had high resistance to 3 main sorghum diseases. The MB-3 and MB-5 mutant lines were resistant to leaf rust and leaf spot Cercospora, and moderately resistant to anthracnose. The lowest infection rate of leaf rust disease was in the MB-5 line, which was 0.0019. This illustrates the low development of rust disease in this line. While the other 3 strains (MM-3, MM-4, and MM-5) consistently reacted moderately resistant to the 2 main diseases of sorghum (rust and anthracnose).
