SCREENING OF SAFFLOWER GERMPLASM ACCESSIONS FOR RESISTANCE SOURCE AGAINST MACROPHOMINA ROOT ROT

Abstract

Fifty germplasm accessions of safflower procured from AICRP on safflower, Marathwada Krishi Vidyapeeth,
Parbhani, Maharashtra were screened for resistance source against Macrophomina root rot under glasshouse
condition. The screening revealed that 4 genotypes viz., GMU-3259, GMU-3262, GMU-3306, GMU-3316
were highly resistant (no seedling infection) whereas 3 genotypes GMU-3265, GMU-3285, GMU-3297 were
resistant and recorded upto 1-10% seedling mortality whereas 5 moderately resistant genotypes recorded 11-
30% seedling mortality. Fourteen genotypes were found moderately susceptible and indicated 31-50% seedling
mortality whereas rests of the accessions were found susceptible or highly susceptible.
