Field evaluation of medium duration finger millet (Eleusine coracana (L.) Gaertn.) genotypes against leaf blast and lesion number caused by Pyricularia grisea (Cke.) Sacc.

摘要

A study was conducted to evaluate the severity of P. grisea [Magnaporthe grisea] infection in 36 finger millet genotypes. Quick blasting cultivars were GE-228, GE-296 and GE-300, showing 10.87, 18.22, 19.00 and 23.55%; 10.55, 19.77, 24.66 and 32.22%; and 10.66, 18.33, 27.00 and 33.00% at 50, 55, 60 and 65 days after sowing, respectively. A gradual increase in lesion number was observed up to 50, 55 and 60 days after sowing. No sudden increase in lesion number from 60 to 65 days was observed in GE-228 (13.88, 14.99, 16.00 and 16.88); GE-239 (13.55, 14.11, 15.00 and 16.88); GE-240 (14.55, 15.22, 17.00 and 18.44); and GE-242 (15.88, 16.11, 16.22 and 16.77) at 55, 60 and 65 days after sowing, respectively.
