Identification of Garlic Genotypes for Resistant Sources against Purple Blotch Disease

Garlic is an herbaceous annual bulbous plant in the family Amaryllidaceae grown for its pungent and edible bulb. Among various biotic factors hindering production productivity, purple blotch plays a predominant role changing crops morpho-physiological characters, thus deteriorating metabolic activity turn affecting yield considerably. Fungicides have been recommended control of disease, however use fungicides expensive not eco-friendly. The best approach to disease by using resistant genotypes. Hence, 37 genotypes were field screened at AINRPOG (All India Network Research Project on Onion Garlic), MARS (Main Agricultural Station), Dharwad against under artificial epiphytotic conditions during Kharif year 2019 identify sources. results revealed that twenty found be (1-10%) five immune (0%) however, ten moderately (11-20%) reaction. remaining two viz., HRG Local DOGR409 susceptible (21-40%) with maximum grade 3 (0-5) scale. None showed or highly reactions blotch. Breeders can make these identified lines developing high varieties.
