Abstract
ABSTRACT
The present investigation titled “Morphological Characterization and Disease
Reaction in Chilli” was carried out at the Experimental Farm, Department of Vegetable
Science, Dr YS Parmar University of Horticulture and Forestry, Nauni, Solan, (HP) during
kharif season of 2019. Twenty genotypes replicated thrice were evaluated for morphological
(DUS), yield traits and disease reaction against Phytophthora blight and Colletotrichum fruit
rot. The experiment was laid out in RCBD in plots of size 2.25 m × 1.80 m. Morphological
characterization for nearly 48 phenotypic attributes based on IPGRI descriptors was carried
out along with disease reaction studies in chilli. The studies resulted in the development of a
comprehensive data set in respect of 20 genotypes of chilli available in the Department. In
addition, significant differences were observed for several yield contributing traits in chilli
genotypes evaluated in the present study. Disease reaction studies revealed that no genotype
was resistant or tolerant to Phytophthora blight and Colletotrichum fruit rot. However, wide
variation in disease incidence/severity and incubation period does indicate some degree of
underlying tolerance towards these diseases in some genotypes.
