Abstract:

Bottlegourd is prone to various fungal, bacterial and viral diseases. Among various fungal diseases, anthracnose, downy mildew and cercospora leaf spot are prevalent in different bottlegourd growing areas. Anthracnose caused by Colletotrichum lagenarium (Pass) Ellis. and Halsted is of major economic importance. The pathogen is seed borne in nature but initiation as well as spread of disease largely depends upon the environmental factors. This disease is widespread under both greenhouse and field cultivation resulting in poor fruit quality and yield. Keeping its economic importance, the experiment was under taken to study the survey among major growing areas and screening of different genotypes under field conditions. During survey minimum per cent disease intensity on leaves was observed in Arjaheri village of Karnal district, whereas on fruits per cent disease intensity was minimum in Dadupur village of Karnal district in Haryana. A total of 24 cultivars/germplasm lines were screened under artificial inoculation conditions created at Plant Pathology farm of CCS HAU, Hisar (Haryana). All the bottlegourd germplasms were sown on 30th June 2016. Two plants per cultivars/germplasm line were maintained and inoculated with a standard spore suspension (3×104 conidia ml-1) at 4-5 leaf stage. Per cent disease intensity was recorded 15 days after inoculation. The entries/germplasms/cultivars and categorized as per the status of disease intensity. Three genotype viz., K-92420, GH-3 and GH-11 were found resistant to anthracnose of bottlegourd whereas, genotypes K-92426 and Gh-18 were moderately resistant to anthracnose and remaining genotypes were susceptible to the disease.
