Evaluation of garden pea genotypes for yield and screening against downy mildew incidence under mid hill conditions of Jammu region

Abstract

Downy mildew caused by [Peronospora viciae (Berk.) Casp.] is one of the most prevalent disease of garden
pea and under mid hill conditions of Jammu region downy mildew causes severe economic losses to farmers.
Twenty genotypes of garden pea were evaluated and screened against downy mildew disease at RARS, Rajouri,
SKUAST-Jammu during rabi seasons of 2007-08 and 2008-09. Based on the results obtained from pooled
data of two years, all the genotypes were grouped into five groups (Group I, II, III, IV and V). Among all the
genotypes, P-89 was found to be the most suitable genotype with minimum downy mildew incidence (10.3%)
and highest yield (217.5 q/ha) under mid hill conditions
