Abstract:
Bottle gourd is an important annual summer cucurbit and a herbaceous climber native to tropical Asia and Africa. The crop remained prone to a number of fungal, bacterial and viral diseases, out of which important and devastating ones are mainly seed borne diseases incited by fungi. Anthracnose disease caused by Colletotrichum lagenarium (pass) Ellis and Halstd is an important fungal disease in bottle gourd crop growing areas of Haryana, which imposed losses to the extent of 25%. In order to manage seed borne pathogens of bottle gourd, resistant varieties serve as an eco-friendly approach. For screening of bottle gourd genotypes against this disease a study was conducted in research farm & laboratory of Department of Plant Pathology. Bottle gourd germplasm lines viz., GH 32, GH 33, GH 34, GH 35, GH 36, GH 37, GH 38 & local variety were screened to find out resistant sources against anthracnose of bottle gourd. Disease intensity (%) for bottle gourd germplasm lines was calculated 60 days after sowing. Screening of germplasm lines revealed that minimum disease intensity of 23.33% was observed in GH 35 followed by 37.04, 44.44 and 44.44%, GH 32, GH 36 and local variety, respectively. None of the line was found completely resistant against anthracnose.
