The rice genotypes differed significantly for leaf blast disease severity for all dates (Figure 1). Initially,
the differences in blast severity among the rice genotypes were not so pronounced, but over time, it
progressed faster in Masuli and CO39 compared to other genotypes (Figure 1). The blast progress in
Radha 11 was slower than Masuli and CO39, but faster in comparison to other genotypes, which was
reflected by its lower AUDPC than Masuli and CO39 but higher than other genotypes (Table 2). Radha
7 and NR 1558 exhibited intermediate disease progress over time. The rest of the genotypes had 5.0%
terminal disease severity values, indicating their higher level of partial resistance.
