Abstract
Twenty one genotypes of garlic (Allium sativum L.) were screened for yield and purple blotch susceptibility under field conditions for two years. Reaction of genotypes to purple blotch disease differed significantly during both years but the pooled analysis revealed that most of the variations were due to genotype × environment interaction. Nine genotypes viz., G-1, G-50, G-323, PGS-4, PGS-14, G-313, PGS-99-1, PGS-98 and PGS-99-2 fell into the category of resistant, five showed moderately resistant reaction to disease (PGS-13, PGS-17, KGS-1, HG-17 and PGS-99-3), four were mild susceptible (G-41, DG-2, DARL-52 and DARL-53) whereas three (G-282, DG-1 and RAUC-5) were susceptible. Genotype PGS-313 exhibited maximum yield (199.6 quintal/ha) followed by PGS-99-2 (154.9 quintal/ha). A strong and negative correlation was observed between purple blotch incidence and bulb weight at genotypic level (-0.99). Key words: Garlic, purple blotch, correlation, yield, genotype × environment interaction.
