Exploring novel resistant sources for chilli leaf curl disease in Capsicum annuum L. germplasm for genetic enhancement.

ABSTRACT: Chilli, as a vegetable and spice, is an important constituent of Indian food. The major constraint that hampers chilli production is Chilli leaf curl disease (ChiLCD). It often leads to heavy yield losses as a result of which the farmers do not prefer chilli cultivation. Therefore, the present investigation has been undertaken to screen and evaluate chilli germplasm conserved in National genebank of India and identify lines resistant to ChiLCD. We screened 500 chilli accessions for four consecutive years (2021-2024) to identify the resistant lines. In the 2021 screening, 16 accessions were found highly resistant, 40 resistant, 33 moderately susceptible, 23 susceptible, and 388 highly susceptible. Accessions showing symptoms of Chilli leaf curl disease in each season were discarded, whereas
