tailieunhanh - Identification of host plant resistance to leaf curl in chilli (Capsicum frutescens L.)

Seventy eight bird chilli genotypes were screened against leaf curl virus. Leaf curl disease scoring was done at 30th, 60th and 90th days after planting (DAP) based on visual symptoms of each observational plant. Initial screening was done under field conditions based on vulnerability index score (0 to 4 scale), disease reaction to each genotype was assigned based on Leaf pubescence which can be observed on the youngest mature leaves and it was classified as sparse (3), intermediate (5) and dense (7). | Identification of host plant resistance to leaf curl in chilli Capsicum frutescens L.
